With Dr. Gordon Arakawa

In the United States, colorectal cancer is the third most common cancer found in men and women. Colorectal cancer happens when cells in the colon or rectum grow out of control. March is Colorectal Cancer Awareness Month, and it’s a good time to get a screening. Here are a few things you need to know.

What is a colorectal cancer screening? Why is it important?

A colorectal cancer screening is when your doctor checks to see if you have any precancerous polyps (small clumps of cells) or signs of colorectal cancer. The screening is used to check for disease even if you don’t have any symptoms. It is important to check for cancer through regular screenings, because early treatment works best to help prevent serious health issues.

Am I at risk for colorectal cancer?

Colorectal cancer is most commonly found in adults ages 65 to 74. However, there has been an increase in colorectal cancer in adults 40 to 49 years old.

You might be more likely to develop colorectal cancer if:

  • You have inflammatory bowel disease.
  • Someone in your family has had colorectal cancer or polyps.

There are other parts of your lifestyle that can affect your risk level for colorectal cancer, including diet, exercise, and use of alcohol and tobacco products.
