If you’re like many of us, the death of actor Chadwick Boseman, star of "Black Panther," hit you hard. Only 43, he died of colon cancer.

Most of us associate cancer with old age, but it can strike at any time. Colorectal cancer, which begins in the colon or rectum, is the third-most deadly cancer in the U.S. Colorectal cancer often has no symptoms in the early stages, but it can be prevented or stopped from progressing with timely screenings.

“Colonoscopy is the one tool that is proven to prevent colon cancer in patients,” said Pawan Rastogi, M.D., gastroenterologist at NewYork-Presbyterian Medical Group Hudson Valley and assistant professor of medicine at Columbia University Vagelos College of Physicians and Surgeons. “That’s not always the case for other types of cancers. But with a colonoscopy, you’re able to detect and test polyps and have them removed before they become cancer.”

Screening Saves Lives

The latest guidelines from the American Cancer Association say that you should begin screenings at age 45, but if there is a family history of colon cancer or other risk factors, screenings may need to start earlier. Colonoscopy is the most common and most highly recommended screening modality for colon cancer.

“I know that sometimes, especially in our younger patients, reading about a colonoscopy can spark a lot of fear,” Dr. Rastogi said. “It’s important to know there are alternative screening options. Your physician can help you decide when screening is right for you.”

Living a Healthy Lifestyle

You can take positive steps to reduce your risk of colon cancer.

“First and foremost, abstain from any sort of tobacco use,” Dr. Rastogi said.

Diets high in red meat and processed food, along with excessive alcohol use, are also risk factors for colon cancer. Cut out saturated fats, reduce your salt intake, and select high-fiber foods like whole grains and colorful fruits and veggies instead.

“This is a cancer that we can all prevent together as long as we continue with screenings and healthy living,” Dr. Rastogi said.
