If you can stay undetectable for a year or a year and a half with ADT, then stopping it does make sense for a lot of people. I know people that have gone years without having to go back on, even though they had high Gleason scores. Some people may have only gone a year, but going back on ADT drops their PSA back down. I know one guy who’s taken five breaks, Each time his PSA comes back but the drugs keep him under control when he starts them again. The only thing he noticed is that the amount of time he can take a break is shorter each time he does it.

It does make sense for even people with aggressive prostate cancer to do this.
