What is a premalignant polyp?
Polyps are not cancerous, but they can be precancerous. This means they will eventually develop into cancer. This process is usually very slow, occurring over 10 to 15 years. The most common form of colon cancer—adenocarcinoma—begins as a precancerous or adenomatous polyp.
How serious is a precancerous polyp?
These types of polyps are not cancer, but they are pre-cancerous (meaning that they can turn into cancers). Someone who has had one of these types of polyps has an increased risk of later developing cancer of the colon. Most patients with these polyps, however, never develop colon cancer.
How often should you have a colonoscopy if precancerous polyps are found?
Even if one or two small, low-risk adenomas are removed, you’re unlikely to develop cancer for at least five years, and repeating the test sooner provides little benefit. So most people need the exam just once a decade, and only a few with larger, more serious polyps may need it more often than every five years.
What does precancerous cells mean?

Is cin2 precancerous?
CIN – The outer surface of the cervix is composed of cells called squamous cells. A precancerous lesion affecting these cells is called CIN. These changes are categorized as being mild (CIN 1) or moderate to severe (CIN 2 or 3).
What’s the difference between benign polyps and cancer?
Different types of polyps look different under the microscope. Polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps. These polyps can be thought of as pre-cancers, which is why it is important to have them removed. What is an adenoma (adenomatous polyp)?
What does high grade dysplasia look like in polyps?
Polyps that are more abnormal and look more like cancer are said to have high-grade (severe) dysplasia. The most important thing is that your polyp has been completely removed and does not show cancer. If high-grade dysplasia is found in your polyp, it might mean you need to have a repeat (follow-up)…
What kind of polyps are not precancerous?
Hyperplastic polyps: These polyps are not precancerous. Doctors generally remove them anyway, just to be safe. Adenomas: Two-thirds of colon polyps are the precancerous type, called adenomas. It can take seven to 10 or more years for an adenoma to evolve into cancer—if it ever does.
What kind of polyps are safe to remove?
The timing of follow-up depends on what kind of polyps the doctor finds, how many, and how big they are. Hyperplastic polyps: These polyps are not precancerous. Doctors generally remove them anyway, just to be safe. Adenomas: Two-thirds of colon polyps are the precancerous type, called adenomas.
