DEAR DR. ROACH: I’m a 76-year-old man who was treated for prostate cancer starting in summer 2017. Following radiation therapy, I was given Lupron injections every six months for two years. It’s been two years since my last injection, but I still experience hot flashes as a result. Will these hot flashes stay with me for the rest of my life? My urologist assured me that the hot flashes would subside approximately a year after the final shot. — D.T.
