Now more than ever, it's important to take a proactive role in your health.

Oswego Health offers a variety of services, including health screenings, health and nutrition education, and diabetic counseling throughout Oswego County.

Colon cancer screening

This 30-minute screening could save your life.

Colorectal cancer is the third-most common cause of cancer-related deaths for both men and women. A colonoscopy is the only screening that can help prevent colon cancer. Early detection and proper removal of colon polyps before they have the chance to turn into cancer leads to a 90% survival rate.

Oswego Health's highly trained and knowledgeable team is committed to providing the highest quality of care to patients.

These doctors provide screening and treatment, right in your community:
