My daughter, just over 30 years old, has had triple negative breast cancer and is now recovering from a second bout with a course of pembro and will shortly restart radiotherapy. She is exhausted from it all and has terrible stomach pains and bloating which may or may not be a side effect of the pembro. She has listenned to various advisors saying she must eat specific items and follow a keto diet. I do worry that the various diet items may be benefiical with regard to cancer reappearing but also adding to the problem. She is steadily losing the will to carry on and I am at a total loss on how to help her, can anyone advise please?
