What Is the Treatment for Serrated Adenomas?


Quick Answer

Treatment for serrated adenomas is usually removal through colonoscopy, or if the adenoma is too large, it is removed through surgery, explains the American Cancer Society. Biopsies can also remove adenomas, although they sometimes leave portions of the adenoma intact.

Full Answer

Adenomas are polyps that resemble the normal tissue of the large intestine but differ under microscopic inspection, states the American Cancer Society. While most polyps are non-cancerous, some adenomas can become cancerous. Patients who have had adenomas are at an increased risk for later developing colon cancer. When an adenoma has a jagged or saw tooth appearance, it is serrated. Serrated adenomas must be removed. Tubular and villous describe the two major growth patterns of adenomas, which sometimes have a mixture of both. Adenomas that are 1/2 of an inch or smaller are usually tubular, while larger ones are more frequently villous. The larger an adenoma is, the more likely it is to develop into cancer.

Patients who have had adenomas should schedule additional colonscopies to ensure that no more polyps develop, recommends the American Cancer Society. The timing of the colonscopy depends on multiple factors, including how many adenomas the patient has had and the characteristics of the adenomas. Villous adenomas are more urgent, as well as those that feature dysplasia, or abnormal cell growth.
