Serrated ademonas do not indicatecancer but are considered precancerous, meaning they present a risk of developing cancer. According to the Association of Directors of Anatomic and Surgical Pathology, most people diagnosed with serrated ademonas do not develop cancer.
An adenoma is a polyp inside the colon that resembles the lining but when checked under a microscope is different in a number of ways. A "serrated" adenoma, for example, has a saw tooth appearance. These adenomas shouldbe removed from the colon in order to reduce the risk of them developing into cancer. If the adenoma is too large to be removed completely with an endoscope, surgery is the next option for removal.
Common polyps found during a colonoscopy screening are not often linked to colorectal cancer, but adenoma polyps are strongly linked to the disease, states the Hopkins Colon Cancer Center website. While only about 10 percent of adenoma polyps actually develop into colorectal cancer, 95 percent of all colorectal cancers develop from adenomas.
Colorectal cancer is the most common cancer in the United States, notes the Healthy Woman website. One out of 20 people develop the cancer at some point in their lives, and it is the leading cause of cancer death for both men and women. The disease is highly treatable, however, and it can be prevented with regular screenings and removal of any polyps.
