What is a hyperplastic polyp in colon?
A hyperplastic polyp is a growth of extra cells that projects out from tissues inside your body. They occur in areas where your body has repaired damaged tissue, especially along your digestive tract. Hyperplastic colorectal polyps happen in your colon, the lining of your large intestine.
Are hyperplastic colon polyps 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 type of colon polyp is most likely to become malignant?
Villous adenoma: This is a type of adenomatous polyp that has a greater potential of becoming cancerous.
At what size do colon polyps become cancerous?
The larger the polyp becomes, the bigger the risk of it developing into colon cancer. That risk increases significantly if the polyp is greater than 10 mm (1 cm); research has shown the larger a colon polyp becomes, the more rapidly it grows.
How common are hyperplastic polyps?
In individuals over the age of 50 years, the prevalence of hyperplastic polyps has been found to be 20–40%.
