Study Reveals New Factor Linking Colorectal Cancer Risks and Vitamin D Deficiency

New evidence gives the correlation between the deficiency in vitamin D and risk rate of colorectal cancer is distinct- age factor, older age could reduce the risk of colorectal cancer.

A new study was carried out by researchers at the University of California San Diego on a strong correlation between level of vitamin D and colorectal cancer. It was reported that deficiency in vitamin D leads to a higher risk rates of colorectal cancer. The main and regular source of vitamin D is sunlight. People experiencing lower UVB rays from sun usually experience deficiency in vitamin D that lead to increase in rate of colorectal cancer risk.

The new study approached towards an exposure of UVB rays at the global level across 186 different countries. The researchers came across several confounding factors to determine the risk of colorectal cancer with respect to deficiency in vitamin D. Such factors are skin pigmentation and smoking that increases the risk of colorectal cancer. Another factor was detected by researchers was the age factor. The age factor plays as vital role in the rate of risk of colorectal cancer. There is a bemusing correlation of distinct-age with UVB exposure and colorectal cancer. There is a large impact of the UVB light exposure on people especially over age of 45 as compared to the younger individuals.

The researchers stated that the older individuals, above the age of 45, are accounted to the large amount of UVB rays of sunlight and could gain more amount of vitamin D than younger ones. The researchers claimed that there are preliminary evidences that older individuals may reduce the risk of colorectal cancer by correcting vitamin D deficiencies. They hypothesised that the increase in rate of colorectal cancer risk could be an outcome of deficiency in vitamin D in people caused due to less exposure to UVB light. Moreover, the researchers suggest to be exposed to UVB light or provide vitamin D supplements to people to reduce the colorectal cancer risk.
