Colorectal polypectomy

My home is in Jeonju, and my in-laws' house is in Jeongeup.

Fortunately, both sets of parents are doing well, but their health is slightly declining.

A few days ago, my wife showed me her mother-in-law's colonoscopy report from Jeongeup via KakaoTalk.

It was found that I have a benign polyp, and after looking into it, I found out it's a pre-cancerous stage.

I'm curious whether the treatment was successful or if more treatment is needed after the test.
