I did both. Chemo then radiation. The chemo made me feel like hell and the radiation burned me bad. After about 6 months when I finally started feeling better my doc said...well, would you do it again? I said...you tried to kill me but it didn’t work. He thought that was pretty funny. lol
My wife had chemo/radiation. It was bad. She looked near death but went through it. It cured her cervical cancer 15 years ago. Now she just discovered she has a hole in her bladder thanks to the radiation. She’ll have surgery to repair that but she’s had the 15 years of life that otherwise she wouldn’t have had.
