Russell Dean Havranek, MD in San Antonio TX specializes in the diagnosis and treatment of gastrointestinal and digestive disorders including particularly important health maintenance roles such as colon cancer screening with colonoscopy. Colon cancer is the second leading cancer killing disease in the U.S. and we can beat it if everyone follows the screening guidelines. My practice also specializes in the treatment of hemorrhoids. While many hemorrhoids can be treated with over the counter methods and changes in diet, I do perform a painless procedure called hemorrhoid banding at my San Antonio TX gastrointestinal clinic.
