Screening for colorectal cancer is a key preventive measure that can both detect the disease early and stop it before it starts.

How Screening Works
Screening involves various tests that can spot early signs of colorectal cancer or even prevent it by finding and removing precancerous polyps. Some common screening methods include colonoscopy, fecal occult blood tests, and CT colonography. These tests help identify potential issues before they develop into cancer.
Different Tests for Different Folks
The best screening test is one that you're able to do. Colonoscopies are thorough but not always available or feasible for everyone, so alternatives like fecal immunochemical tests (FIT) or multitarget stool DNA tests can be used. Each test has its pros and cons, but all aim to catch problems early.
Weighing the Risks and Benefits
While screening has clear benefits, it's not without risks. Procedures like colonoscopy carry a small risk of complications, such as perforation. However, the benefits of early detection and prevention often outweigh these risks, especially as the tests become more refined and accessible.
