Expert Digestive Care: Screening and Treatment Close to Home

March is Colorectal Cancer Awareness Month, a time to focus on the importance of screening and early detection. Colorectal cancer is the second leading cause of cancer-related deaths in the United States, but with regular screening, it is also one of the most preventable. Colonoscopy is the gold standard for detection, allowing physicians to identify and remove precancerous polyps before they develop into cancer. 

At Foundation Gastroenterology, Colon & Rectal Surgery of New England, and Foundation Surgery, we are committed to providing expert care and advanced technology to help keep you healthy. Our teams work together to ensure that patients receive comprehensive evaluation, diagnosis, and treatment for all digestive and colorectal concerns. 

Advanced Screening with AI-Powered Technology 

We are proud to be the first in southern New Hampshire to offer enhanced colonoscopies using the GI Genius™ intelligent endoscopy module. This advanced AI technology improves polyp detection, identifying abnormalities that might be missed by the human eye. By increasing accuracy in screening, GI Genius™ helps detect polyps earlier before they become cancer. 

Our team of skilled gastroenterologists and surgeons provides a full range of digestive health services, including colonoscopy screenings, diagnosis, and treatment for common digestive disorders. We deliver compassionate care using the latest medical advancements to ensure patients achieve the best outcomes.
