4 ANTI-CANCER SPIRULINA TREATMENT APPROACHES

1. SPIRULINA FOR CANCER PREVENTION

Many people have reason to worry about cancer - spirulina can help protect you from this deadly killer. >>CLICK HERE TO LEARN MORE<<

Who is at greatest risk?

1. People with a genetic predisposition or family history of cancer
2. Smokers and ex-smokers, as well as people exposed to second-hand smoke
3. People exposed to toxins and toxic heavy metals (read more)
4. People exposed to radioactivity and electromagnetic radiation including cellphone radio waves, microwaves, infrared radiation, sunlight, ultraviolet radiation, X-rays, and gamma rays.
5. People that have experienced or continue to experience extreme mental stress or trauma.
6. Athletes - Strenuous exercise can cause elevated levels of Reactive oxygen species (ROS) - a major cause of cancer.
A daily dose of fresh spirulina can help reduce the risk of cancer by attacking cancer cells at the earliest stage when they are most vulnerable.
2. SPIRULINA FOR ALTERNATIVE CANCER TREATMENT

Spirulina offers an alternative treatment that attacks cancer cells, while promoting robust health in non-cancer cells. >>CLICK HERE TO LEARN MORE<<

Cancer chemotherapy and radiation therapy kills healthy cells as well as cancer cells, leading to a host of ‘side effects’ that can destroy your quality of life during treatment and for decades after.
One of the benefits of spirulina treatment is that it can be started immediately and the dosage adjusted according to results. Being a natural functional food, there is no risk of overdose.
Spirulina will not interfere with your quality of life or cause side effects during or after treatment. It can be used together with other treatments.
3. SPIRULINA FOR COMPLEMENTARY CANCER TREATMENT

Spirulina combines well with chemotherapy, increasing patient tolerance, maintaining blood cell production, and improving treatment outcomes - see research below. >>CLICK HERE TO LEARN MORE<<

Spirulina helps to maintain healthy cell health during and after radiation therapy, helping to increase radiation tolerance and repair DNA damage to healthy cells. It has been shown to improve radiotherapy outcomes in difficult cancer cases. 
interesting facts from research studies below on this page:

- Combining spirulina treatment with chemotherapy reduced the need for chemotherapy treatment modification (patients tolerated treatment better), reduced myelosuppression, and improved patient immune function after chemotherapy. 
- Chemotherapy patients treated with spirulina experienced less weight loss, maintained better nutrition and quality of life, and sustained better hemoglobin levels. 
- Complementary spirulina therapy can reduce radiation dosage to alleviate side effects while building health in non-cancerous cells to reduce treatment-induced damage to the body. 
- Spirulina treatment is effective in helping healthy cells to restore patient health after damage by chemotherapy and radiation therapy. It could also help repair DNA damage caused by treatment, thereby reducing tumour spread and metastasis.
4. SPIRULINA FOR CANCER SURVIVORS

Science shows that cancer cells can remain in a dormant state for long periods – even decades - before re-emerging - Spirulina treatment can help prevent this. >>CLICK HERE TO LEARN MORE<<

Spirulina treatment helps to rebuild and maintain vibrant health - while working to destroy dormant cancer cells and tumours to reduce the risk of cancer recurrence.
Dormant cells are characterized by a general metabolic slowdown as they sleep and hide from the immune system. This is an ideal time for spirulina therapy to locate and destroy cancer cells and tumours.

Research: Spirulina Compound Phycocyanin Prevents Metastasis, Effective Against Multi Drug Resistant Cancers

Phycocyanin in spirulina may help prevent and counter adenocarcinoma, AML leukemia, brain cancer, breast cancer, colon cancer, histiocytic sarcoma, liver cancer, lung cancer, nose cancer, oral cancer, ovarian cancer, pancreatic cancer, prostrate cancer, sinus cancer, skin cancer, squamous carcinoma, stomach cancer, throat cancer, and thyroid cancer tumors.

Phycocyanin - a major component of spirulina - has been shown to be effective in cancer treatment. 
This research investigates the main mechanisms of action and explores its role in the resistance of cancer cells to chemotherapy.
An extensive examination of the literature shows that phycocyanin has no single specific target, but acts on the cancer cell membrane, cytoplasm, and nucleus with different mechanisms of action.
We show that Phycocyanin targets the MDR1 gene, cytoskeleton proteins, and COX-2 enzyme , making it capable of killing cells resistant to chemotherapy.

CANCER DRUGS NO LONGER SATISFACTORY
The drugs currently available for cancer treatment, such as vinca alkaloids and taxanes, are not satisfactory in their effectiveness, because of the resistance developed by cancer cells, a major factor in the failure of treatment.
The rapid mutation of cancer cells have led to many becoming multi-drug resistant to chemotherapeutic drugs. 
Many chemotherapies are toxic to healthy tissues, impairing the quality of life, weakening the immune system, and sometimes generating irreversible damage to the recovery power of the patient.

PHYCOCYANIN FROM SPIRULINA
Phycocyanin has been verified to have significant effects on the multiplication of uterine cervix carcinoma cells (HeLa) with no negative effects on healthy non-cancer cells.
The recombinant b-subunit of phycocyanin is toxic to metastatic cells with no negative impact on non-cancer cells.
Hence, phycocyanin can be regarded as an agent for the prevention of metastasis.

EFFECTIVENESS OF PHYCOCYANIN FROM SPIRULINA
Researchers have reported the antiproliferative and cytotoxic capacity of phycocyanin with anti-tumor effects against histiocytic sarcoma (thyroid and brain cancers) acute myeloid leukemia (aml) (blood and bone marrow cancers) adenocarcinoma (breast, stomach, prostate, lung, pancreatic and colorectal cancers) squamous carcinoma (throat, mouth, sinuses, nose and neck cancer) colorectal adenocarcinoma (colon and rectum cancers) estrogen-responsive breast cancer hepatocellular cancer/hepg2 (liver cancer) lung adenocarcinoma/a549 (lung cancer) ovary adenocarcinoma/skov-3 (ovarian cancer) mcf-7 - human breast cancer tpa-induced skin tumorigenesis (skin cancer), and lung cancer.

PHYCOCYANIN ANTI-CANCER MECHANISMS OF ACTION
Phycocyanin does not have a single mechanism of action. 
Based on existing evidence, we hypothesize that it has a diversity of effects. 
The mechanisms by which phycocyanin generates its antitumor effects: 
- Cell cycle arrest in specific phases 
- Modification of the cellular redox state through the modulation of enzymatic and non-enzymatic antioxidants COX-2 
- Induction of apoptosis and necrosis Intracellular accumulation and potentialization of the effects of doxorubicin (a traditional anticancer drug)
Phycocyanin is a strong candidate for overcoming chemoresistance. 

CONCLUSIONS 
The studies in this paper have undeniably shown the chemotherapeutic potential of phycocyanin. 
In addition to its inhibition of cell proliferation, which is a basic requirement, it has the important ability to circumvent multi drug resistance and the lack of specificity of current anticancer drugs.

Research: Phycocyanin from Spirulina Shown in 25 Studies to Dramatically Reduce Cancer Tumors within Hours - 2021

Combined results of 25 independent research studies show that phycocyanin from spirulina dramatically reduces tumors in Skin, Prostrate, Pancreatic, Lung, Liver, Colon, Cervical and Breast Cancer as well as the spread of Leukemia and Histiocytic cancer. 

Using phycocyanin together with existing anti-cancer drugs could improve the therapeutic outcome while reducing unpleasant treatment-related side effects.
This independent research review studied the effects of phycocyanin from spirulina on various tumor cells.
The results are summarized in this research document.

SAFETY
Studies of spirulina have not revealed any toxic effects on kidney, liver, reproductive system, or body physiology during or after the administration of acute or chronic doses.

PHYCOCYANIN
This study focused on an ingredient of spirulina: phycocyanin is an active ingredient of spirulina and was shown to have therapeutic properties, including anti-oxidant, anti-inflammatory, immune-modulatory and anti-cancer activities.
Medical applications of phycocyanin are of interest due to its anti-inflammatory, anti-viral, anti-cancer, immunostimulatory and anti-oxidant properties.
Recent anti-cancer studies of phycocyanin revealed a significant inhibitory effect on the growth of cancer cells.
Multiple mechanisms have been found, including the induction of apoptosis, cell cycle arrest, inhibition of DNA replication and the generation of reactive oxygen species (ROS).
Cancer cell death was significantly increased, with no damage to cells from healthy tissues, which makes it a candidate for chemotherapeutic applications.

Research: Phycocyanin Compound in Spirulina Kills Dangerous Histiocytic Sarcoma Cancer in Days

Histiocytic sarcoma is difficult to treat and extremely dangerous. Phycocyanin from spirulina was shown to kill histiocytic cancer cells in hours.

Histiocytic sarcoma is a rare and difficult to treat cancer that is extremely dangerous. It arises in the subcutis, with invasion to adjacent tissues and metastasizes to one or more distant sites (including the lungs, liver, bone marrow, uterus, lymph nodes, gastrointestinal tract, soft tissues, and the spleen and other abdominal organs). 
Histiocytic sarcomas can involve any site within the central nervous system, including the brain parenchyma, spinal cord, and meninges.
Untreated, the clinical course of disseminated histiocytic sarcoma is rapid and fatal. 
Overall, response rates to treatment are poor and survival times are short (3-4 months).

Phycocyanin Treatment of Histiocytic Sarcoma
Independent research into the effect of phycocyanin on a AK-5 histiocytic tumor line showed phycocyanin-induced apoptotic death in AK-5 cells starting just 12 hours after treatment, with 80% cell death achieved after 72 hours.

Research: Spirulina Stops the Proliferation of Lung Cancer Cells - 2021

Powerful antioxidants in spirulina stop the proliferation of human non-small cell lung cancer cells while protecting healthy non-cancerous cells. 

Independent research verifies that Spirulina could be a promising treatment of cancer cells.
- Spirulina has a concentration-dependent antioxidant effect
- Spirulina damages cancer cells by disrupting the cell cycle
- Spirulina protects normal cells through its antioxidant activity
- Spirulina forces cancer cells to apoptose (self-destruct) through biochemical alterations

Lung cancer is the third most common cancer among men and the fourth common cancer among women. 
It is divided into two main groups: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC includes more than 85% of lung cancers.

OXIDATIVE STRESS
Oxidative stress is caused by am imbalance in the body's redox status which causes free radicals to increase and cause cell and DNA damage. 
Oxidative stress leads to cancer, metastasis, and invasion. 
ROS can react with DNA which leads to miscoding during replication. 
This can lead to irreversible mutations in the genome that lead to cancer. 

ANTIOXIDANTS 
Antioxidants are compounds which reduce the damage done by reactive oxygen species. 
Spirulina is a rich source of powerful antioxidant compounds including phycocyanin, chlorophyll, myxoxanthophyll, beta-carotene, zeaxanthin and xanthophyll. 
These compounds activate cellular antioxidant enzymes, inhibit lipid peroxidation and DNA damage, scavenge free radicals, and increase the activity of superoxide dismutase and catalase. 

This study investigated the anti-cancer effects of Spirulina on the human non-small cell lung cancer A549 cell line. 
Results showed that Spirulina extract had a remarkable effect on the lung cancer cell cycle – it arrested the cell cycle in phase G2 so cells didn't enter phase M and the proliferation of cancer cells was prevented. 
Results showed that the greater the dose of spirulina antioxidants, the less viable the cancer cells became. 
These results confirm previous studies’ results that Spirulina has significant inhibitory effects on cancer cells while at the same time protecting healthy cells.

Research: Spirulina Reduces Endometrial Cancer Tumors and Inhibits Metastasis - 2022

Phycocyanin from spirulina can inhibit tumor growth and repress metastasis of Endometrial cancer (EC) - sometimes called uterine cancer or cancer of the uterus - the most common gynecological malignancy worldwide.

Advanced endometrial cancer, with aggressive features, has a very poor five-year survival rate of less than 30%, with a high recurrence rate.
Metastasis is a major challenge in cancer treatment accounting for tumor metastasis and a high risk of recurrence.

Spirulina components phycobiliprotein, phycocyanin, allophycocyanin, and C-phycocyanin are powerful nutraceutical compounds with the ability to inhibit tumor growth and metastasis.
Recent studies have confirmed that spirulina compounds can inhibit the growth and spread of different cancer cells, including breast cancer, lung cancer, esophageal squamous cell carcinoma, and colon cancer.

This research found that spirulina compounds inhibited the TGFβ1-induced migration of human endometrial cancer cells and suppressed peritoneal dissemination in vivo.
Research studies have also found that spirulina compounds strengthen the effect of chemo-or radiotherapy and minimize dose-related side effects, thereby improving the efficacy of cancer therapy. 

CONCLUSION
Spirulina compounds can be considered a nutraceutical with the ability to inhibit endometrial cancer tumor growth and metastasis providing an effective therapeutic strategy for metastatic endometrial cancer.

Research: Spirulina Substantially Decreased Proliferation of Pancreatic Cancer

Spirulina substantially decreased proliferation of pancreatic cancer due to potent antioxidant activity, inhibition of mitochondrial production of reactive oxygen species and subsequent changes in intracellular redox status. 

Inhibition of pancreatic cancer growth was evidenced from the third day of treatment.
Pancreatic cancer - sometimes called the silent killer - is among the most deadly forms of cancer globally, with one of the lowest survival rates.
Spirulina has been found to trigger cell death in a variety of tumor cells.
The aim of this study was to evaluate possible anticancer effects of spirulina and spirulina-derived tetrapyrroles.
The anti-proliferative effects of spirulina were shown in vivo, where inhibition of pancreatic cancer growth was evidenced from the third day of treatment. 
These effects were at least partially due to their potent antioxidant activity, inhibition of mitochondrial production of reactive oxygen species and subsequent changes in intracellular redox status.
This data supports a chemopreventive role for spirulina with promising potential for its broad use in the chemo-adjuvant treatment of cancer diseases.
This assumption of more generalized use of spirulina in cancer chemoprevention is supported also by recent data demonstrating anti-cancer potential of this algae on liver as well as breast carcinogenesis.

Research: Spirulina Treatment Stopped Breast Cancer Cell Proliferation After 24 hours

Breast cancer is the most common malignant disease in women worldwide, and its incidence is steadily increasing, particularly in developing countries (World Health Organization).
While conventional medicine has made progress in the treatment of breast cancer, pharmacological interventions are fraught with complications, including many known and unknown legal and ethical issues. 
Also, breast cancer cells quickly acquire resistance to chemotherapeutic drugs via different cell signaling mechanisms.
Various studies have demonstrated anticancer effects of spirulina and its active ingredients both in vitro and in vivo, and our research group has reported a chemo-preventive action of spirulina in liver carcinogenesis.
To our knowledge, the present study is the first to demonstrate an in vivo chemo-preventive effect of spirulina against DMBA-induced mammary carcinogenesis.

We show that spirulina clears breast tumors, a finding confirmed by histological analysis and microscopic observations. 
In vitro studies revealed that spirulina treatment of MCF-7 breast cancer cells resulted in cell growth arrest 24 hours after treatment and cell death after 48 hours.

The researchers conclude that spirulina exhibited remarkable antitumor activity by inhibiting cell proliferation and that spirulina clears tumor cells from the mammary gland and contributes to the formation of a newer epithelial layer.

This independent research confirms the anti-cancer activity of spirulina and strongly supports the chemopreventive properties of spirulina.
Spirulina has a high concentration of primary and secondary health-promoting metabolites.
It contains lipids (linolenic, linoleic, oleic, stearidonic, eicosapentaenoic, docosahexaenoic, and arachidonic acids), vitamins (B, D, E, ascorbic acid), minerals (primarily potassium but also calcium, chromium, copper, iron, magnesium, manganese, phosphorus, selenium, sodium, and zinc), and bioactive compounds (chlorophyll a, xanthophyll, β-carotene, zeaxanthin and phycobiliprotein complexes such as C-phycocyanin or allophycocyanin) that have anticancer activity.

Lung cancer and respiratory tract carcinomas are the most common cancers and the main cause of cancer deaths among males and females in developed countries.

This research studies the anticancer potential of spirulina against human non-small-cell lung carcinoma.
The effect of spirulina on cell viability, proliferation, and morphology and the influence on regulation of the lung cancer cell cycle, induction of apoptosis, and expression of cell cycle/apoptosis-related proteins was evaluated.

Results
Our studies revealed that spirulina significantly reduced lung cancer cell viability and proliferation, which was accompanied by cell cycle inhibition in the G1 phase, induction of cancer cell death, and prominent morphological changes.
The results obtained provide evidence of the anti-cancer activity of spirulina against lung cancer cells and strongly support the knowledge of the chemopreventative properties of spirulina.

Research: Spirulina Lowers Cancer Risk and Prevents Tumors in Humans - 2021

Independent studies reveal that Spirulina reduces the risk of developing breast cancer, pancreatic cancer, skin cancer and squamous cell carcinoma. 

Spirulina can can prevent tumor formation, prevent oxidative damage of DNA often responsible for cancer, and enhance the repair of DNA damaged by radiation.

This 2021 review explores spirulina's anti-oxidative, anti-microbial, anti-inflammatory, anti-hypertensive, anti-tumor, anti-obesity, immuno-modulatory and probiotic health benefits and how these can improve public health.

Free radicals formed in our body scavenge electrons from other molecules, resulting in cell and DNA damage that can lead to cancer. 

Antioxidants in Spirulina can neutralize free radicals and hence prevent cell damage. 

Carotene and phycocyanin are among the major anti-cancer spirulina components.

Studies show that Spirulina antioxidants lower the risk of developing various cancers in humans. 

Adverse effects that arise from cancer therapies may be more dangerous than cancer. 

Spirulina can reduce the after effects from chemotherapy and existing treatments. 

Various studies have confirmed the effectiveness of Spirulina in inhibiting cancers by acting on the human immune system and through a DNA repair mechanism. 

Spirulina contains phycobiliproteins - C-phycocyanin, allophycocyanin and phycoerythrin - which have bioactive properties against cancer. 

Other research showed that polysaccharides in Spirulina enhanced repair activity of radiation damaged DNA. 

Further studies showed a significant reduction in the viability and effects of carcinoma, with the arrest of the G1 phase of the cell cycle. 

In human breast adenocarcinoma cell lines MDA-MB-231, the mitogen-activated protein kinase (MAPK) signalling pathway was inhibited by phycocyanin from spirulina, revealing its anti-cancer effect. 

Research concluded that spirulina carotenoids, chlorophyll and phycocyanin provide pronounced biological functional properties including the prevention of tumor formation and enhancement of the immune system.

Research: Spirulina Improves Chemotherapy Outcomes in Cancer Patients with Malignant Tumors - 2019

This study sought to confirm whether Spirulina can limit the side effects of chemotherapy in patients with malignant tumors.

Chemotherapy Side Effects can Interfere with Treatment

Chemotherapy is non-specific and targets not only cancer cells, but is also toxic to non-cancer cells.

Because of this toxicity, patients often experience side-effects - including myelosuppression, granulocytopenia, febrile neutropenia, thromboembolic events, and neurosensory toxicity. 

These can interfere with treatment, necessitating skipped chemotherapy sessions, alternative chemotherapy regimens, or even discontinuation of chemotherapy.

Myelosuppression Disrupts Treatment, Health, and Post-Chemo Quality of Life

Myelosuppression (bone marrow suppression) causes a decrease in the production of blood cells responsible for providing immunity, carrying oxygen, and those responsible for normal blood clotting.

Myelosuppression increases the risk of blood disorders like anemia, infections and bleeding issues. 

The Research

100 cancer patients randomized into control or treatment groups received four cycles of chemotherapy.

The treated group consumed Spirulina for the first two cycles while the control group did not.

Cancer Types

Cancer patients in the study included cases of colorectal cancer, lung cancer, breast cancer, pancreatic cancer, gastric cancer, esophageal cancer, bladder cancer, and gallbladder carcinoma.

Roughly half the patients tumours had metastasized - this did not impact on the positive results achieved.

Results During Treatment 

- Neutrophil (a type of white blood cell that act as your immune system's first line of defense) levels were higher in the treated group after Cycle1 and Cycle2.

- Patients who received spirulina treatment had a significantly lower rate of severe myelosuppression

- Less modification of the chemotherapy regimen was necessary for spirulina treated patients

Results After Treatment 

- IgM level and number of CD8+ T cells increased in the treatment group but decreased in the control group

- Spirulina reduced myelosuppression and improved immune function after chemotherapy in patients with malignant tumors

These results are in line with previous studies demonstrating the benefit of Spirulina supplementation in chemotherapy patients.

Conclusion 

The results support the hypothesis that Spirulina reduces myelosuppression and improves immune function after chemotherapy in patients with malignant tumors.

Research: Anti-Cancer Activity of Spirulina - Lung Cancer and Pancreatic Cancer - 2022

Spirulina's unique potential for cancer treatment lies in its significant inhibition of cancer cells while protecting normal healthy cells. 

The anticancer effect of Spirulina is associated with suppressive effects on the migration and invasiveness of tumor cells with different antiangiogenic characteristics.
Spirulina is a functional food that stands out for its rich composition of bioactive compounds such as chlorophylls, carotenoids, phycocyanins, phenolic compounds, and natural antioxidants that support anticancer, neuroprotective, probiotic biological activities and stimulate the human immune system.
Spirulina increases the human immune system and response by inducing tumor necrosis, phagocytosis, and the production of interleukin – mechanisms that result from the wide range of sulfate groups, sulfate esters, and amines found in spirulina polysaccharides.
The powerful antioxidant activity of spirulina affects the cell cycle of lung cancer, increasing the production of reactive oxygen species and cell membrane lipid peroxidation.
Spirulina demonstrated inhibitory effects on the migration and invasion of pancreatic cancer, allowing the regulation of mRNA and VEGF-A protein expressions in tumor cells, inhibiting ERK activation and suppressing the expression of ERK-regulated proteins.

Conclusions
Spirulina's potential for cancer cell treatments lies mainly in the significant inhibitory effects on cancer cells while protecting normal cells. 
The anticancer effect of Spirulina is associated with suppressive effects on the migration and invasiveness of tumor cells with different antiangiogenic characteristics.

 

Trusted Source: Spirulina Effective Against Liver, Testicular, Oral, Melanoma and Colon Cancer

This article summarizes extracts from Examine.com - the largest database of nutrition and supplement research on the Internet.

Independent research shows spirulina reduced DNA fragmentation in induced liver cancer by 72% and in testicular cancer by 91%. 
Oral cancer in tobacco users was significantly reduced, melanoma cancer cells had a 50% reduced invasion and reduced migration, and spirulina provided protection against colon cancer.
In studies that measure DNA fragmentation in healthy cells in response to toxins (a carcinogenic process), spirulina reduced DNA fragmentation from a 31.2% increase to just 8.8% in the liver, and from a 10.2% increase to just 0.9% in the testes.
Spirulina appears to have the capacity to reduce tumor size or otherwise retard tumor growth rates.
Low dose spirulina treatment has been noted to decrease the rate of oral lesions in tobacco users.
An in vitro study investigating spirulina polysaccharide noted that B16-BL6 Melanoma cells had 50% reduced invasion and reduced migration.
Spirulina compound phycocyanin is associated with protecting from colon cancer in part due to its ability to inhibit excessive production of COX-2 in colon cells, which tends to be increased in colon cancer cells.

LIterature Review: Cancer Prevention with Spirulina - An Overview

This independent overview of spirulina protection against cancer highlights the chemo-protective and radio-protective capability, and the benefits of enhanced tumoricidal NK activation. 

Specific studies highlight the impact of spirulina in preventing Carcinoma, Melanoma and Fibrosarcoma Oral Cancer, Leukemia, Liver Cancer, Stomach Cancer, Skin Cancer, Colon Cancer and Breast Cancer.

A great deal of research has confirmed Spirulina’s promise in the prevention and treatment of various cancers.
The anti-cancer research has been conducted on dried spirulina as well as on compounds isolated from Spirulina and examined a variety of cancers in different organs.
Spirulina cancer research began in 1998 with a study showing significant inhibition of carcinoma, melanoma and fibrosarcoma. 
Further research has also shown that Spirulina compounds ‘have chemo-protective and radio-protective capability’, with a later study showing spirulina significantly increased the levels of interleukins 1 and 3 and tumor necrosis factor alpha.
Several recent studies show cancer related benefits.
Two studies have shown an effect against oral cancer and a third demonstrated enhancement of antitumor natural killer cells.
A study of particular interest concluded that orally administered spirulina enhanced tumoricidal NK activation and inferred a potential for antitumor immunotherapy.

Further research has also shown
- a 49% decrease in the proliferation of leukemia cell lines
- a 50% decrease in the proliferation of hepatocellular carcinoma (liver cancer) cell lines
- a significant decrease in HeLa cells in vitro compared to control cells
- the inducement of apoptotic features including cell shrinkage in HeLa cells
- impedance of the reproduction of HeLa cells • potent antiproliferative agent against human melanoma cells and human breast adenocarcinoma MCF-7 cells

Many researchers find the spirulina compound phycocyanin to be a truly exciting compound with potent antioxidant, anti-inflammatory and anti-cancer properties. 
This compound is only found in spirulina and a few other algae.
An interesting study compared the activity of spirulina with Vitamin E and germanium-132 in pre-cancerous crypts in the colon. 
While all three compounds had some inhibitory effects, after 9, 13 and 16 weeks the number of aberrant crypts was significantly less in the spirulina group.
Another study found spirulina inhibited skin and stomach tumors.

Fresh spirulina provides hundreds of beneficial compounds that are lost during the processing and storage of dried spirulina powder or tablets.
Fresh spirulina provides up to 8 times more nutrients and 20 times more antioxidants and anti-cancer substances than found in dried spirulina powder or tablets.
Almost any dose of fresh spirulina will provide more benefits than shown in the research studies - almost all the research was conducted with dried spirulina.

Dosage Control: Spirulina Portions (SP)

We measure fresh spirulina in Spirulina Portions, written as SP-1 (single portion), SP-2 (Double portion), SP-3 (Triple portion), and so on.
SPRU Shots contain SP-1.5 (One and a half Portions), while frozen Stix are available in Sp-1, SP-2, and SP-3 strengths.

Fresh Spirulina Dosage for Cancer Prevention & Treatment

One to two portions (SP-1 to SP-2) of fresh spirulina daily should help prevent cancer development for predisposed adults and children.
A similar dosage may help to control and suppress dormant cancer in survivors.
Consider double- or triple-dosing for a week or two when starting with SPRU - and periodically thereafter - to bolster anti-cancer benefits. 
People in cancer treatment may wish to greatly increase their dosage. Cancer clinics in the United States regularly prescribe SP-15 to SP-30 daily doses of fresh spirulina. 
You can't take too much - people on fresh spirulina fasts consume SP-15 to SP-30 every day for thirty to a hundred days and experience remarkable health benefits.
