My 79-year-old mother has Stage IV kidney cancer that has spread to her lungs, breast, and liver. She has tried, unsuccessfully, five different chemo treatments during the last 14 months. The side effects of the last chemo drug were severe, including nosebleeds, abdominal pain and swelling, and loss of bladder control. She is so desparate to continue treatments that she did not inform her doctor or me of the severe side effects until 5 days after they started. She will not listen to family members but is willing to believe anyone who offers her a "miracle cure." I am concerned that her doctors will keep trying treatments as long as she keeps asking for them (and Medicare is willing to pay for them). I no longer think that she is capable of making informed decisions about her medical care. I think its time to stop treatments and call hospice. My father has her health care POA but wants to follow her wishes. Is there anything I could/should do?
