Standard Calcium Offers Prolonged Protection From Colorectal Adenomas

Calcium Offers Prolonged Protection From Colorectal Adenomas

Calcium supplements decrease the risk of colorectal adenomas 5 years after treatment ends, according to study results published in the January 17 JNCI.
Dr. John A. Baron of Dartmouth Medical School and colleagues followed participants of the Calcium Polyp Prevention Study, a double-blind, placebo-controlled, randomized trial of calcium supplements for subjects with a previous colorectal adenoma from 1988 to 1992. Researchers sent participants annual follow-up questionnaires that addressed medical events, including colonoscopies, as well as use of medication, vitamins, and dietary supplements. They obtained posttreatment information from 1999 to 2003 for 822 of the original 930 subjects.
