Selenium reduces chances of colorectal cancer in women

Although people only need a small amount of selenium, this essential micronutrient found in soil plays a key role in metabolism, has antioxidant properties, and may help prevent colorectal cancer.

Doctors in this study measured circulating levels of selenium in 966 men and women with colorectal cancer and in 966 similar men and women without colorectal cancer. While there was no link between selenium levels and cancer in men, women who had the highest circulating levels of selenium were 36 percent less likely to develop colorectal cancer compared to women with the lowest selenium levels.
