Reducing or Eliminating Alcohol Consumption Reduces Risk of Developing Oral Cavity and Esophagus Cancers
Alcohol has long been a part of human culture and social gatherings. While moderate consumption may have some potential health benefits, excessive and long-term use of alcohol can lead to a range of serious health problems, including alcohol addiction and liver disease. One of the lesser-known but equally significant health risks associated with alcohol consumption is the increased risk of developing oral cavity and esophagus cancers.

Patient Stories
Trip to Health Worth Taking
When you find a good doctor, it makes the trip from Maryland to New Hampshire worth taking. That is exactly what George Sneed does. Sneed has extremely debilitating ulcerative colitis when it is active. His ulcerative colitis sometimes caused Sneed to go to the bathroom 10 to 15 times in four hours, making work or anything physical extremely difficult. Fortunately for Sneed, those times are now few and far between. He attributes much of his remission to the great care he has received from Dr. McLean.
Trust Keeps Him Coming Back
William Shakespeare once said, “Men of few words are the best men.” Granite State Gastroenterology patient John Moody, 75, of Derry, would certainly agree when it comes to Dr. Knut Roalsvig. “He’s a man of few words, but every word is important and means something,” said Moody. “Dr. Roalsvig asks a lot of questions, listens, takes copious notes, and is very thoughtful. You can almost see his brain working. He doesn’t let anything get by.”
