Hi, Thanks for writing in. Sorry to hear about the cancer your mother is having. It appears that his primary is in the breast and now it has spread to the liver making it stage 4 cancer. Stage 4 cancer have a survival of 2 years with recommended treatment and support. If his general condition is weak then she must be provided with nutrition containing high level of proteins. Please give her fluids and semi solids that is easy to digest. Ask her the food she likes and try to give it in small quantities are frequent intervals. If she he having hepatic enephalopathy then her protein intake should be closely monitored and strict diet followed. Once her general health is better then she will be able to tolerate chemotherapy should the doctors advise her another chemotherapy. In many patients the newer chemotherapy agents work well and can extend her life for few months. You can ask her doctors to give her pain relief medicines. Once her pain is reduced then she will feel more comfortable and then start eating better. By going for combination chemotherapy you can slow down the disease progress. Please do not worry.
