DEAR DR. ROACH: I am having a "push endoscope," or forced endoscope, tomorrow. They said they found a lesion in a CT scan and want to look into it further. Is "lesion" a fancy name for cancer? -- B.E.
ANSWER: The word "lesion" is a Latin word for "injury." In medical parlance, it means pretty much anything that is abnormal. While it is true that doctors will use the term "lesion" to describe something that will later turn out to be cancer, "lesions" definitely are not always cancer.
