hi, i have a friend who has cancer (stage4).. she had series of chemo already and her last treatment of chemo was for her liver. however, when the cancer cells became active again, she went to a much even stronger chemo and after her 1st strong chemo treatment, she got sores all over her mouth, barely eats, has edema in her feet and hands and now experiencing diarrhea, all her labs were not good. she's currently confined in a hospital but are these signs that she might be the end of her battle.
