The Journey from Polyp to Cancer
Most colorectal cancers start as small growths called polyps in the colon or rectum. These adenomatous polyps can grow larger and turn cancerous over time, often taking about 10 years to do so. Regular screening can catch these polyps before they become cancerous, which is why it's so important.
Why Screening is Crucial
Screening for colorectal cancer can save lives by catching the disease early when it's easier to treat. It can also prevent cancer by removing precancerous polyps. Although screening tests vary in accuracy, they all help reduce the number of deaths from colorectal cancer. Tests like fecal occult blood tests and colonoscopies are vital tools in this fight.
Who is at Risk?
Some people have a higher risk of developing colorectal cancer due to factors such as family history, certain genetic syndromes, and inflammatory bowel disease. It's important to know your risk level because it influences when you should start screening. Those at average risk are usually advised to start screening at age 45.
