You didn't read the post that my response was to. It was a post about a 12 year old niece of the poster who has T-cell lymphoma and is committed to fighting for her life and undergoing chemotherapy etc. I agree with you that the 17 year old’s decision to not have a very likely curative therapy is misguided.
I had six months of chemotherapy twelve years ago. Piece of cake. The doctor also removed five lymph nodes to be sure there were no loose cancer cells floating around. Haven’t had any problem since. I’m just grateful that there is a treatment for cancer. It’s a horrible disease.
