What happens if I have a precancerous polyp?

How serious is a precancerous polyp?

It is considered an abnormal growth, but in many cases, they are found to be benign (commonly in the early stages). However, over time polyps can become large and malignant if they aren’t treated. Many polyps are found to be pre-cancerous, which means they have the potential to turn cancerous if they aren’t removed.

How long does it take for precancerous polyps to turn into cancer?

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. Overall, only 5% of adenomas progress to cancer, but your individual risk is hard to predict.

Is it normal to have precancerous polyps?

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.

Approximately 1% of polyps with a diameter less than 1 centimeter (cm) are cancerous. If you have more than one polyp or the polyp is 1 cm or bigger, you’re considered at higher risk for colon cancer. Up to 50% of polyps greater than 2 cm (about the diameter of a nickel) are cancerous.

Can colon cancer develop in 2 years?

Colon cancer, or cancer that begins in the lower part of the digestive tract, usually forms from a collection of benign (noncancerous) cells called an adenomatous polyp. Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years.

Can colon polyps cause weight gain?

Colorectal adenomas are known as precursors for the majority of colorectal carcinomas. While weight gain during adulthood has been identified as a risk factor for colorectal cancer, the association is less clear for colorectal adenomas.
