My mother was diagnosed with TCC one month ago. The cancer has spread to her liver, lymph nodes, and spine. She is unable to walk on her own at this point and the doctors have ruled out chemotherapy due to her weakness. Yesterday we went to a homeopathic doctor and he gave us a few things to try, graviola being one of them. It is in liquid form and the instructions are to give 12 drops twice a day. The bottle reads 'Standard Enzyme Company of North America' - Gravi-Plus. I'm not sure if you can order this on the internet but you may want to try a local nutritional store or find a homepathic shop. I hope this helps. :-)
