Multivitamin use doesn't impact colon cancer outcomes, study finds

Patients with colon cancer who used multivitamins during and after being treated with post-surgical chemotherapy did not reduce the risk of the cancer returning or their dying from it, according to researchers. In a study of 1,038 patients with stage III colon cancer, the researchers found that while multivitamin use had no beneficial effect on patients' outcomes, it also did not have a detrimental effect.
