Colorectal cancer (CRC) is a serious disease that can be deadly, but the good news is that it is also one of the most preventable types of cancer. By getting screened, we can find and remove small growths (polyps) before they turn into cancer. Screening is not just about finding cancer early—it can actually stop it from developing in the first place.
Why Screening Matters
Screening helps find colorectal cancer early when it is easier to treat. It also helps doctors remove polyps, which are small growths that could turn into cancer. If cancer is found early, the treatment works much better. In fact, people with early-stage colorectal cancer have a 90% chance of living five years or more after diagnosis (American Cancer Society, 2024). But since many people hesitate to get screened or avoid it, only 40% of cases are found this early. This is why regular screening is so important.
Different Screening Tests
There are several ways to get screened for colorectal cancer. Here are the most common tests we recommend:
- Colonoscopy – This is the best screening test. It is a procedure that allows your provider to look inside your entire colon and remove polyps right away if they are present. It is done once every 10 years for most people.
- Stool DNA Test (e.g., Cologuard) – This test looks for cancer-related DNA and blood in your stool. It is done at home every three years.
- Fecal Immunochemical Test (FIT) – This test looks for hidden blood in your stool. It is simple and done at home once a year.
When to Start Screening
Providers recommend that most people start getting screened at age 45. If you have a family history of colorectal cancer or other risks, you may need to start earlier. Talk to your provider to find out what is best for you.
Making Screening Easier
Some people avoid screening because they are scared, don’t know enough about it, or think it is too much trouble. With at-home options like the FIT and stool DNA test (Cologuard), getting screened is easier than ever. If you are worried, talk to your provider—they can help you choose the best test for you.
