What our patients have to say about us:

Pauline Avery wasn’t worried about her symptoms. But then she described her mild stomach pain and bowel changes to Betty Pomerleau, MD, her primary care physician at Lincoln Physicians. “Dr. Pomerleau said ‘let’s check it out,’ so I was scheduled for a CT scan,” Ms. Avery recalls. The test revealed a mass in her colon, so she went for a colonoscopy, which provided a more detailed diagnosis, as well as devastating news.

John Yates was not eager to have hernia surgery this past summer. But, Mr. Yates couldn’t ignore the symptoms which included pain in his lower left abdomen and a bulge that became more prominent throughout the day.

John Yates
In my own mind, I had overblown the difficulty of having a colonoscopy, but it turned out to be a piece of cake. The sedatives we use these days are terrific. But when I woke up afterwards, Dr. Raj Devarajan, my gastroenterologist, gave me the bad news: he found a mass in my large intestine. He said this kind of mass turns out to be cancer in the vast majority of cases. I would need to have surgery.
