Colorectal cancer is the second leading cause of cancer death in the U.S., but it is often treatable when detected early. Colorectal surgeon Dr. Ulrik Wallin says the cancer of the colon or rectum usually starts out with a small, precancerous polyp that can then develop into cancer. In its early stages, there are often no symptoms. “But as it grows, you can develop symptoms such as bleeding, abdominal pain, changes in stool consistency, sometimes also weight loss,” Dr. Wallin said. The three main risk factors of colorectal cancer are age, family history and lifestyle factors. These include high red meat consumption, increased alcohol consumption and smoking. You can lower your risk by making lifestyle changes, and regular screenings do save lives. “Screening is actually something we know can detect early stages, and it can remove precancerous polyps,” Dr. Wallin said. “In that way, we can reduce our risk to develop colorectal cancer.” Colonoscopy screenings should start at age 45 without other risk factors. If you have a family history of colorectal cancer, you should talk to your healthcare provider about when to start screenings. “We know that the actual prognosis is going to be significantly affected if you detect it early,” Dr. Wallin said. “Early stages are associated with a better prognosis, whereas later stages such as it spreads to other organs, have much worse prognosis.” Dr. Wallin says if you have a normal colonoscopy, you’ll need one every seven to 10 years. If you have polyps, you’ll need one more frequently as directed by your doctor. “Screening with a colonoscopy is very, very important,” he said. “I know this is something that doesn’t sound pleasant. It is something that is very safe. It is something that can actually prevent colorectal cancer.” To learn more about your healthcare options, visit the Optum Care Washington website.
