Is 30 mm large for a colon polyp
You posted your question quite some time ago so hopefully you have gotten a clean bill of health by now but to answer your question; Yes, 30 mm is large for a colon polyp. Hopefully, your doctor got it all and did a follow up colonoscopy soon afterward.
I'm scheduled for another colonoscopy in 5 months which will be in August. Why is another one necessary? To see if it grows back?
How big is the average colon polyp? Does the size of a polyp indicate problems?
