A new study has shown remarkable association between vitamin D and colorectal cancer. According to the researchers at the Dana-Farber Cancer Institute, vitamin D can help in the prevention of colorectal cancer in some people.
This is the first stance when the association between vitamin D and the response of immune system against cancerous cells has been established in a sizable human population.
The researchers explain vitamin D helps in boosting the functioning of immune system in some people against cells in tumors.
For the study, the researchers collected the data from 170,000 individuals and used two long-term research projects related to health-tracking, the Nurses’ Health Study and the Health Professionals Follow-up Study. Out of the total participants, 318 had colorectal cancer and 624 persons had no cancer. The researchers collected blood samples from all participants and then they were tested for 25-hydroxyvitamin D, which is a substance produced from liver and is derived from vitamin D.
The findings showed that the participants having high levels of the vitamin D-derived substance possessed below-average risks of developing colorectal cancer with tumors teeming with cells from the body’s immune system.
Senior study author Shuji Ogino said, “This vindicates basic laboratory discoveries that vitamin D can interact with the immune system to raise the body’s defenses against cancer.”
Ogino further added that it may be possible in the future to say how boosting the levels of vitamin D in the body and the increased functioning of immune system will be able to lower the colorectal cancer risks.
The study was detailed in the journal Gut and was funded by the Paula and Russell Agrusa Fund for Colorectal Cancer Research, the Bennett Family Fund, the Friends of Dana-Farber Cancer Institute, the Entertainment Industry Foundation and the National Institutes of Health.
