My Cousin Had Breast Cancer Last Year And They Removed

My cousin had breast cancer last year and they removed her left breast, when they started the chemo she was too sick from other problems, diabetes, conjested heart, high blood pressure, etc. so they stopped the chemo until she gets better, she has been in the hospitals so many time, had a couple blood transfussions, and she is in the hospital now and they said that her pancrease has failed, she is taking morphine, lots of licquids, vitimins, and other stuff, she cannot eat or drink nothing, she also suffer from a alchol problems, and she was sneaking and drinking after surgery, she is about to be released from the hospital in a couple of days to a Hospice skilled nursing home, she was also told by her oncologoly doctor that the cancer is gone for now, so I got happy, but then she said that she have so many other things going on within her, and now I'm scared for my cousin again, she has good health Insurance, she worked most of her life, she just had a drinking problem early in life. my question is can she ever recover from all these illinesses?
