I have a couple relatives who refused chemo–but these were people in their 70s who’d already been thru chemo a few years before for the same type of cancer–and in both cases they had very little chance of cure–only to extend their lives (suffering) by a few months. So, perfectly reasonable for them to refuse the 2nd round of chemo.
But with a young person with curable cancer, I think it is OK to force her to take the treatment. She doesn’t know what she’s talking about–getting it all from her mother who is ignorant. (I knew a women, mother of 4 in her early 40s, who believed in these “nutritional” or alternative treatments. . .which of course didn’t work. After wasting months “believing” in an unproven “cure,” finally went to an oncologist who said it was too late, that if she had come in months before, she might’ve had a chance. I have another friend whose son is in his late 20s, battling cancer for the 3rd time. He had chemo/radiation and surgeries before, a few years ago. After a suspicious scan in Nov., she has been giving him some herbal/nutritional junk (imo) that she “believes in.” He is seeing doctor soon–hopefully soon enough to get some treatment with a better chance of helping.
