The most common symptom of early-stage colorectal cancer is often no symptom at all. Unfortunately, symptoms don’t always appear until the cancer has spread or reached an advanced stage. When colorectal cancer is caught early, it’s one of the most curable cancers.

Dr. Michael Lajin, board-certified gastroenterologist at Sharp Grossmont Hospital, explains 6 ways to prevent colorectal cancer.

The most important thing you can do is get screened. There are several different tests, but a colonoscopy screening is considered the gold standard.

Besides detecting cancer, a colonoscopy screening helps doctors identify any abnormal growths — called polyps — that can occur in the colon and rectum. Doctors also can remove polyps during the same procedure. Polyps can sometimes turn cancerous, so removing them early can prevent cancer before it starts.
