Lifewatch: Vitamin D

BOSTON -- A new study from the Dana-Farber Cancer Institute says Vitamin D may extend the lives of people who have colon and rectal cancer.

Doctors checked Vitamin D levels in more than 300 people diagnosed with the cancers.  Patients with higher levels of the vitamin were 50% less likely to die from their cancer during the study.

The study's lead author says Vitamin D should definitely be studied further to see if it has any benefit to treating colorectal cancer.

Previous studies have linked Vitamin D to lowering the risk of other illnesses like breast cancer and peripheral artery disease.

It's known as the sunshine vitamin because the body produces it when it's exposed to sunlight.

The study appears in the Journal of Clinical Oncology.
