Like Biden said, just Google for free tests
My GP recommended a “home kit” in place of a colonoscopy last year as routine for my age.
I happened to have some issues during this time and scheduled a regular screening.
My gastro told me he has seen so many of these “kits” turn up as false positives for cancer and patients coming to him scared to death. And, in some cases, miss possible cancer.
He has a great reputation in our area and has treated several family members.
