Withholding these vitamin supplements helps to control prostate cancer

Oncologists in Whittier, California successfully controlled prostate cancer in a 71-year-old patient whose case had been diagnosed as untreatable. They simply had the man stop taking extreme amounts of vitamin B12 and folic acid.

Case study
The doctors have described their noteworthy medical success in the Journal of Medical Case Reports. Having found an increased concentration of the 'prostate cancer protein' PSA in their patient's blood, they subsequently diagnosed prostate cancer by means of a puncture biopsy. The Gleason score was 3+4=7, which means that, although the cancer cells were spreading throughout the prostate itself, they had not yet spread further.

The doctors first treated the patient with cocktails of anti-androgens, but he failed to respond; despite this treatment, his PSA continued to rise. They then began chemotherapy and administered docetaxel.

Once again, the patient failed to respond, and his PSA rose even higher.

Supplementation
The patient was also taking the supplement Intrinsi B12/Folate manufactured by Metagenics. Each tablet contains 800 micrograms of folic acid/folate and 500 micrograms of vitamin B12 in addition to a complex of substances intended to improve the absorption of the vitamins. The man took 10 pills each day, amounting to 8 milligrams of folic acid and 5 milligrams of vitamin B12 daily.

Two weeks after he had stopped taking such a very large dose, his PSA began to decrease.

Folic acid & cancer
In biomedical science, the fact that large amounts of synthetic folic acid increase the risk of cancer is not a new one.

As early as 1946, Science published an animal study in which hefty doses of synthetic folic acid - which was then called "liver Lactobacillus casei factor" - accelerated tumor growth. [Science. 1946 Nov 8;104(2706):436.]

Two years later, in 1948, a study appeared in the New England Journal of Medicine in which administration of a drug that neutralized folic acid in children with leukemia slowed the development of the disease. [N Engl J Med. 1948 Jun 3;238(23):787-93.]

Cells that divide quickly need folic acid. This also applies to quickly dividing cancer cells.

Cabbage can help prostate cancer survival Quercetin boosts inhibitory effect of green tea for prostate cancer Metastudy: selenium helps prevent prostate cancer

Cabbage can help prostate cancer survival
This study suggests that prostate cancer sufferers can halve the rate at which the disease develops if they eat cabbage nearly every day.

Quercetin boosts inhibitory effect of green tea for prostate cancer
Men in the early stages of prostate cancer may be able to slow down the course of their disease by drinking five cups of green tea and taking one gram quercetin daily.

Metastudy: selenium helps prevent prostate cancer
This discovery was made by nutritionists at the University of East Anglia, who compared and reanalysed data from 12 epidemiological studies of more than 13,000 men.
