Colonoscopies at Lakewood Health System

Colon cancer screening looks for early signs of cancer in the colon and rectum—often before symptoms appear. Several screening options are available, and your healthcare provider can help you choose the one that fits your health needs and personal preferences.

A colonoscopy is considered the gold standard for screening. During the procedure, a healthcare professional uses a thin, flexible tube with a camera to examine the entire colon. Polyps or abnormal tissue can be removed immediately, which helps prevent cancer from developing.

Best for:

• Individuals at average or increased risk

• Anyone with a personal or family history of polyps or colon cancer

• People who want a comprehensive, once‑every‑10‑years exam (if results are normal)

*Most insurance coverage will pay for a screening colonoscopy at 100% as a preventive benefit.

Stool-based screening tests, such as Cologuard, look for DNA changes or hidden blood in the stool that could signal cancer or precancerous conditions. These tests are done at home and mailed to a lab.

Best for:

• Individuals at average risk

• People who prefer a noninvasive, at-home option

• Those needing screening more frequently (every 1–3 years depending on the test)

If a stool test comes back positive, a follow-up colonoscopy is recommended.

• Early detection saves lives. Colon cancer often develops silently with no early symptoms. Screening finds issues before you feel them.

• It can prevent cancer entirely. Removing precancerous polyps stops cancer before it starts.

• It’s recommended for all adults starting at age 45. Earlier screening may be needed for those with risk factors such as a family history of colorectal cancer, certain genetic conditions, or inflammatory bowel disease.
