Dr. David Samadi advised patients on prostate cancer medications to talk to their doctors about the new FDA warnings. These prostate cancer medications can cause diabetes, heart attack, stroke and sudden death. The drugs lower testosterone levels and give men symptoms of menopause. Samadi believes it's best to cure prostate cancer early on with robotic surgery, which completely removes prostate cancer and brings PSA levels to zero. Prostate cancer can't be prevented but healthy diets and exercise help.
