I have been On firmagon for 3 weeks . I was diagnosed with prostate cancer which metastasized to my pelvic bone in 2 spots . I am now awaiting results from a pet bone scan , does anyone out there have any information on how well this firmagon works and for how long ? The side effects with hot flashes have not been too bad but yesterday I played golf in 90° weather and I felt out of breath at times . I am 68 years old and basically in Great health except for this prostate cancer .
