Is a 6mm polyp big?

If they found precancerous cells, there is no need for any additional treatment as long as they removed the entire polyp. Removing the tissue stops the development of cancer. Since you are still at an increased risk, we will likely recommend repeating the screening every three to five years in the future.

What is the treatment for a cancerous colon polyp?

Since stage 0 colon cancers have not grown beyond the inner lining of the colon, surgery to take out the cancer is often the only treatment needed. In most cases this can be done by removing the polyp or taking out the area with cancer through a colonoscope (local excision).

What does a cancerous polyp look like?

Most polyps are protrusions from the lining of the intestine. Polypoid polyps look like a mushroom, but flop around inside the intestine because they are attached to the lining of the colon by a thin stalk. Sessile polyps do not have a stalk, and are attached to the lining by a broad base.

What size polyps are cancerous?

These are called adenomatous polyps. The size of the polyp correlates with the development of cancer. Polyps less than 1 centimeter in size have a slightly greater than a 1% chance of becoming cancer, but those 2 centimeters or greater have a 40% chance of transforming into cancer. Overall, the incidence is about 5%.

Should I worry about precancerous polyps?
