Calcium May Help Prevent Colon Cancer in Older Adults

Between 1995 and 1996, more than 500,000 AARP members from California, Florida, Pennsylvania, New Jersey, North Carolina, Louisiana and Atlanta, Georgia and Detroit, Michigan filled out a questionnaire that asked participants to provide answers about their lifestyles and diets, including information about dairy consumption. Responses from the 198,903 women and 293,907 men, ages 50 to 71, were then compared with state cancer registries, allowing researchers to see which of the study participants developed some form of cancer over the years. Researchers then analyzed their findings, comparing the amounts of calcium consumed by study participants with cancer diagnoses up to 2003. They found that women that had reported consuming higher levels of calcium (1,300 mg/daily) reduced their risk of colon cancer by about 23 percent, compared to those that reported consuming the least amounts of calcium. In addition, the study supports that women that consumed higher levels of calcium also lowered their overall cancer risk, although there were no additional benefits found for women consuming more than 1,300 milligrams of calcium each day. Men that had reported higher levels of calcium (1,500 mg/daily) in their diets lowered their risk of developing colon and other digestive cancers by 16 percent when compared with those that consumed the lowest levels (500 mg/daily) of calcium. However, there was nothing found in the study to suggest that higher calcium intakes in men reduces overall cancer risk.

The study, which was published in the Archives of Internal Medicine, had to be carefully conducted to avoid involving other factors in the findings. Modifications were made to be sure that cancer risks were lowered by calcium consumption alone, since participants with higher calcium intakes were most often white, college-educated adults that were more physically active and tended to drink and smoke less, which also lower cancer risks. Experts have suggested that calcium may reduce the risk of colon and other digestive cancers because it adheres itself to fatty acids and bile, which can cause damage to the large intestine. Preventing this damage may lessen the development of abnormal cells, lowering a person's risk of cancer in these areas. Additional studies are still necessary to establish a solid link between calcium intake and reduced cancer risk. Still, this study’s findings may lead to additional research, resulting in improved cancer prevention methods. Cancer treatment is most effective when the cancer is caught early on.
