I have a loved one with permanent nerve damage from chemo. We’re very happy the chemo was successful, but imagine a combo of numbness and constant pain for the rest of your life in all your fingers, which becomes dramatically more severe with exposure to cold. It makes make simple daily life tasks from driving, to cooking, etc. far more difficult. They do not tell patients in advance they are going to continue the treatments until the point where permanent damage happens. You only realize after going through it that this was the plan all along. It makes medical talk about informed consent feel ridiculous. The severity fluctuates, but it has already been like 7 years, and this is never going away. It is not for “a while”.
Convenience.
