Patient Reviews
Mar 25, 2023
I have been putting off getting a colonoscopy, thinking that I was super low risk for cancer. As a compromise, my primary care physician ordered me a Cologuard. Much to my surprised it came back as positive for possible colon cancer. My primary care physician recommended Dr. Treyzon. Dr. Treyzon scheduled me immediately for a colonoscopy, he removed a pre-cancerous polyp and had it biopsied. Fortunately, everything was detected early. I found Dr. Treyzon very caring, very thorough and answered all of my questions. I am very lucky to have found him.
