Colon cancer screening: when to get tested and why it matters
Colorectal cancer, often called colon cancer, is one of the most common cancers in the United States. The good news is that it is also one of the most preventable and treatable when found early. According to the Centers for Disease Control and Prevention (CDC), regular screening plays a key role in detecting colon cancer before symptoms appear.
Getting screened for colon cancer can help detect issues early and even prevent cancer from developing. Many colorectal cancers begin as precancerous polyps, which can be found and removed during screening. Understanding when to get screened and how often to follow up can help you take an important step toward protecting your health.
Key facts about colon cancer screening
- Colon cancer screening can detect cancer before symptoms appear
- Screening can find precancerous polyps so they can be removed before they turn into cancer
- Most people should begin screening at age 45, according to the U.S. Preventive Services Task Force
- Early detection greatly improves treatment outcomes
What is colon cancer screening?
According to the CDC, colon cancer screening is a test used to detect colorectal cancer or precancerous growths before symptoms begin. Many colorectal cancers start as polyps, which are abnormal growths in the colon or rectum.
Screening tests can find these polyps early, and in some cases, remove them before they develop into cancer. They can also detect cancer at an earlier stage, when treatment is more likely to be successful.
When should you get screened for colon cancer?
According to the CDC and the U.S. Preventive Services Task Force (USPSTF), most adults should begin regular colon cancer screening at age 45 and continue through age 75. After age 75, screening decisions should be made in consultation with your doctor.
The timing and frequency of screening can vary depending on your health history and risk factors. Some people may need to be screened earlier or more often.
How often should you get screened?
The frequency of colon cancer screening depends on the type of test used and your individual risk level.
For example, a colonoscopy (one of the most common screening methods) is typically recommended every 10 years for people at average risk, according to the USPSTF. Other screening options may be done more frequently.
Talk with your doctor about which screening option is right for you and how often you should be tested.
Who may need to start screening earlier?
Some people may need to or be screened more frequently or begin colon cancer screening before age 45.
According to the CDC, certain risk factors may require earlier or more frequent scanning. You may be at higher risk if:
- You have a genetic syndrome such as familial adenomatous polyposis (FAP) or Lynch syndrome
- You have inflammatory bowel disease, such as Crohn’s disease or ulcerative colitis
- You have a family history of colorectal cancer or polyps
If any of these apply to you, talk with your doctor about when to begin screening and which test is best for your situation.
What else can you do to lower your risk?
While screening is the most effective way to detect colon cancer early, certain lifestyle choices may help lower your overall risk.
According to the American Cancer Society, steps that may help reduce risk include:
- Keeping a healthy weight
- Increasing physical activity
- Eating a diet rich in fruits, vegetables, and whole grains and low in animal fats.
- Limiting alcohol consumption
- Quitting smoking and tobacco use
These habits support overall health and may help reduce your risk of developing colon cancer over time.
