Since 1950, the rate of colon cancer among young adults has quadrupled. The reason for this dramatic increase, according to Dr. David Sherer, anesthesiologist and author of Bottom Line’s What Your Doctor Isn’t Telling You blog, is the change in diet and exercise among this group. Young people today are more likely to eat a poor diet full of fat and refined carbohydrates than their predecessors…and they are likely to get less exercise, both of which can potentially lead to cancer. Dr. Sherer suggests that not only should young adults eat a healthier diet and engage in more physical activity, they also should watch for signs of cancer—including any changes in bowel habits and abdominal pain—and contact their doctors if they have any concerns.

David Sherer, MD, is an American physician, inventor, and author. He currently practices anesthesiology in the suburbs of Washington D.C. and is a tireless advocate for hospitalized patients.
