Vitamin D Can Reduce Endometrial Cancer Risk in Obese Women

Endometrial cancer is most commonly diagnosed in women between the ages of 55 and 65. It is the most frequently occurring cancer in the female genital tract in the United States with 35,000 cases reported every year. Obesity is among the main risk factors associated with this type of cancer. It increases the risk by two times and raises the chance of recurrence by six. In 70-75 percent of cases, the symptoms are diagnosed in stage 1 itself. Being diagnosed with this kind of cancer it is followed by surgery which is the primary treatment for this ailment.

Researchers at the Georgetown Lombardi Comprehensive Cancer Center have found that intake of Vitamin D supplements can reduce the risk of this cancer in obese women. The results of their study are published in the September 2010 issue of the online journal Cancer Prevention Research. It was funded by grants from the National Cancer Institute and the Department of Defense.

How Endometrial Cancer Risk is Reduced by Vitamin D

  • The experiment was carried out on experimental obese mice in a laboratory.
  • Feeding a vitamin D enriched diet to obese mice reduced the risk of this cancer by 25 percent.
  • When these mice were not fed with this diet, the risk increased by 67 percent.
  • The exact mechanism of how vitamin D is so beneficial against this cancer in obese women is yet to be understood and is the topic of further research.

More than 50 percent of women in America are overweight or obese and depend on a progesterone drug to prevent endometrial cancer. Progesterone is also notorious for its breast cancer causing side effect. Sunlight is a natural source of vitamin D. It is for this particular reason that the researchers believe exposure to sunlight on a daily basis can prove beneficial for obese women.
