What to know
- You can take steps to lower your risk of getting colorectal cancer.
Screening for colorectal cancer
Colorectal cancer usually starts as an abnormal growth in the colon or rectum called a polyp. You can have polyps for years before they turn into cancer. They may not cause any symptoms.
Colorectal cancer screening can find polyps so they can be removed before they turn into cancer. In this way, colorectal cancer is prevented. Screening can also find colorectal cancer early, when treatment works best.
Other steps you can take
You can also lower your risk of getting colorectal cancer by:
- Getting enough physical activity.
- Keeping a healthy weight.
- Not using tobacco.
- Limiting the amount of alcohol you drink or not drinking alcohol at all.
