"I was doing [the daytime chat show] 'Lifechangers' and my HLN show was going. My wife and I had this great relationship, very active sexually. This could screw everything up. It was a terrible feeling," Pinsky said about hearing the diagnosis from his doctors.
Pinsky, 55, returned to work 10 days after his operation in July and has since made a complete recovery, People.com said.
"I'm cancer-free," Pinsky said. "The erectile function is normal, sex drive is normal, bladder works normally. And I don't have to worry about prostate cancer."
Pinsky is the former host of the reality shows "Celebrity Rehab with Dr. Drew" and "Rehab with Dr. Drew."
