I started getting mine at 3 months, and have gotten one each time since-each 3 months. The doc says he needs to examine for any unusual growths, scar tissue buildup and general colon health. So I still have a lifetime of them to look forward to. I will say they aren't anywhere as bad/painful/uncomfortable now as before surgery. Now before, it just plain hurt to have the prostate palpated like that by an expert at it...
Now it just an inconvenience..
