Colon cancer and rectal cancer affect people of all ages, ethnicities, and lifestyles — no one is immune.

Yet we have a powerful defense against this disease: screening. With screening — the process of detecting cancer or precancerous growths in the colon or rectum (known as polyps) — colorectal cancer is one of the most preventable of all cancers.

In fact, some experts believe an uptake in screening over the past couple decades has contributed, at least in part, to declining incidence rates of colorectal cancer in older adults.

The fact is, routine screening is recognized as the most effective way to reduce risk, and the United States Preventive Services Task Force says screening should begin at age 45 for average-risk individuals.

So how do screenings prevent colorectal cancer?

That’s a matter of polyps and timing.

The development of colorectal cancer can take about 10 years, though some people may experience faster or slower growth.

Most colorectal cancers begin as a polyp. While most polyps are harmless, a small fraction could develop into a precancerous condition and then cancer.

Before these polyps have time to become cancerous, polyps of any nature can be spotted and removed during a colonoscopy.

If a doctor removes a polyp that had the potential to become cancerous if left to grow, then he or she may have prevented colorectal cancer.

In addition to colonoscopy, a variety of screening methods exists to determine whether an individual has a precancerous condition or cancer, though these tests have different sensitivities.

The stool DNA test from Cologuard can detect evidence of the highest risk pre-cancers and early cancer using both blood and DNA analysis. A fecal immunochemical test or FIT test analyzes blood in the stool. If precancer or cancer is detected in either of these options, a doctor will order a colonoscopy for further evaluation.

Unfortunately, millions of Americans skip screening and pass on a crucial opportunity to find and treat precancerous conditions or early cancer. It is critical to identify cancer in an early or local stage before it spreads and becomes more difficult to treat.

Patients have a 91 percent five-year survival rate when colorectal cancer is found at an early stage but just a 15 percent when cancer is found in an advanced stage and has spread to distant organs.

Want to get screened?

Great! Your doctor can tell you when to begin screening, which tests you can use, and how often you should be screened. Indeed, timely detection and removal of precancerous growths can prevent colorectal cancer.
