PSA - get your colonoscopy
Yep - had mine two weeks ago.
I had been on a 3-year cycle (the old man died of colo-rectal cancer -- NOT a nice way to go), then went to a 5-year cycle when I was clear the last time. Four polyps this time - all benign but two pre-cancerous - so I'll be back on a 3-year rotation again.
Easy-peasy though, at least compared to dying of colon cancer or dealing with a colostomy bag. Get your colonoscopy - don't wait!!
