The Vitamin D receptor is found in colon cancer cells. When Vitamin D binds to the receptor in the cancer cells, it may stop cancer cells from growing abnormally and may cause cancer cell death. Vitamin D has been used in other research studies and information from those other research studies suggests that Vitamin D may help in the treatment of colon cancer. Participants will receive either high-dose vitamin D or standard-dose vitamin D. The study drug will be given 14-28 days prior to your surgery. The number of days will depend on when the surgery is scheduled.2014-07-152169218NCT02172651
