I did too! It changed the way I look at chemo/radiation treatment. It’s gonna be a big no for me. The family member that developed cancer decided to go aggressive. Life did not exist for that person outside of doctors offices medications, pain and puking. It only prolonged their existence by maybe a year and a half. I say existence because there was no real life. The chemo and radiation did more damage than had the cancer taken them away.
Same for my friend who died of brain cancer. She'd have been better off letting the cancer take her. It would have been six months instead of 18 months, but I think they would have been better quality of life.
