I am interested in talking to a Dr. about radiation treatment for prostate cancer.

You should see your Primary Care Doctor instead. There's no point in waiting 20 hours to been seen at the hospital only to be waved off to a specialist. If your PCP is unavailable, try a walk-in urgent care Clinic like Patient First. You can ususally get time with a doctor in under and hour or two. Ultimately, your insurance plan should be the biggest deciding factor in where you go. Does your health insurance require you to have a referral to see a specialist? If yes, obtain it from your pcp or a doctor at Patient First. If no, book an appointment directly with a radiation therapy specialist and skip the middle man. In either case, going to the ER is pointless unless you are in critical about-to-die conditions

Hi Mr. Collins, Im in total agreement with Mr. Cadigans' response. Couldn't have said it better myself. Wishing you the best.
