Can Diarrhea Be a Symptom of Colon Cancer?

Jeffery Nelson, M.D., FACS, FASCRS, is an experienced colorectal surgeon who serves as Surgical Director of The Center for Inflammatory Bowel and Colorectal Diseases, part of The Melissa L. Posner Institute for Digestive Health and Liver Disease at Mercy. Dr. Nelson recently responded to a query from Best Life magazine regarding whether diarrhea can be a symptom of colon cancer and what preventive steps can best be taken.

"Overall, any change in bowel habit, such as diarrhea, can be a sign of colon cancer. Diarrhea can be either a secretory process (the tumor leaks fluid) or from partial obstruction and overflow around the tumor. Sudden constipation or difficulty passing stool along with bleeding are seen more commonly. Abdominal pain and anemia are of concern, as well.

Colon cancer is an insidious tumor and grows very slowly, typically presenting when it is more advanced. It can take 10 to 15 years before it may cause symptoms. Because of this reason, people should get colorectal cancer screening starting at age 45. You should know your family history, especially any history of colorectal cancer or polyps in any first-degree relatives (parents and siblings). One of the best ways to prevent colon cancer is to eat a high fiber diet and avoid using alcohol and tobacco products."
