Yet in my recent colonoscopy,my GI found 10+ polyps scattered around my traverse colon, sigmoid
colon,
and rectum. The largest one of size 2.5cm turned out to be cancerous
and I had to have a radical emergency surgery to get 10cm of my sigmoid colon & rectum resected. I also did genetic testing which turned out negative. As far as reducing polyps, the only thing I know is to avoid red meat. I'm afraid that there's nothing much you can do with it.
