Vitamin D may help reduce the risk of colon cancer, study

Posted:  Friday, January 23, 2015

A new study has found that high blood levels of vitamin D may reduce the risk of colon cancer by interacting with the immune system.

The observations were published in the journal Gut. The study enrolled 318 people who had developed colorectal cancer, and 624 people for the control group. All of the participants had their vitamin D levels measured before cancer development.

The researchers observed that the higher the levels of vitamin D, the lesser the chances of developing colorectal tumours. They believe that vitamin D interacts with the immune system to prevent the growth of these malignant tumours.

A tumour not only consists of cancer cells but also other cells including T lymphocytes or T cells that modulate its rate of division. Vitamin D seems to upregulate these cells, which translates to a better prognosis.

Commenting on the study, the lead researcher Dr. Shuji Ogino said, “This study really shows that vitamin D has an effect on immunity and this is the first study to show that in a human population. Vitamin D boosts immunity not just in cancer, but in fighting infections as well.” Although further studies are required to support this data, it is indeed good news to the ears of all.
