Vitamin D and cancer

Christer Sundqvist

Vitamins are absolutely essential for the body’s metabolism to function. The role of vitamins in the emergence of cancer has been studied very carefully. All vitamins are important but especially a deficiency of vitamin D can cause cancer to occur. It is therefore important to ensure that you get plenty of vitamin D daily (Sources: sun, fish, eggs, fungi, vitamin D fortified foods, dietary supplements).


The most important thing is that the vitamins are taken in as natural a form as possible. A versatile diet is preferred, but it can be recommended that vitamins and antioxidants should be taken as a dietary supplement.


The research shows that vitamin D provides a 20-60% protection against, among other things, breast cancer, colon cancer, uterine carcinoma, brain tumor, myeloma etc. Canadian Cancer Society (CCS) recommends all adults to take vitamin D supplements. The decision was made after several research results suggested that the vitamin provides protection against many types of cancer. The MD Anderson Cancer Center puts the thumbs up for vitamin D for cancer patients, but calls for more research.


It has been found that people who develop cancer often have low levels of vitamin D in their blood. “We hope for progress in preventing cancer through these recommendations,” says Heather Chapell, who is responsible for the CCS cancer prevention program. Low levels of vitamin D are associated with survival following surgical removal of colon cancer as shown in a new study. Low vitamin D levels were associated especially with colon cancer and breast cancer, according to a 20-year cohort study.


In the scientific journal British Medical Journal, a study was recently published in which vitamin D had a protective effect against cancer. High levels of vitamin D in the blood gave a 20 percent lower risk of developing cancer, both in women and men. The risk of liver cancer decreased as much as 50 percent, especially in men.
