How fast do colon polyps grow back after removal?
Research indicates that as many as 60 percent of polyps may grow back within three years. Also, about 30 percent of patients who've had polyps removed develop new ones. This is why it is important to talk to the care team about follow-up screening within five years after the polyps are removed.
What are the chances of colon polyps returning?
Based on the World Health Organization (WHO) classification, polyps can be divided into four types: adenomatous, inflammatory, hyperplastic, and hamartomic polyps. Due to the high risk of adenoma-carcinoma sequence, resection is suggested for colorectal polyps. However, polyps often recur, at a rate of 20% to 50%.
How do you prevent colon polyps from returning?
A diet high in fruits, vegetables, and unprocessed grains can be especially beneficial for gut health and the prevention of colon polyps. Folic acid and folate: Folic acid and folate can help to prevent the formation of polyps in people who regularly consume at least 400 micrograms per day.
Do polyps grow back in the same place?
