Sir my uncle suffering from stomach cancer. Initially doctor told it is primary stage and tumour was removed through surgery also veenat 400 tablet given for daily but after two months again he started vomiting. Due to endoscopy it is confirmed that cells are spreads to nearby by origin areas and doctor says it is on 4th stage and suggested for chemotherapy. In between, Sir I heard about graviola flowers (soursop) which is used as juice to kill the cancer cells directly and it has some side effects also. Requesting to whether I should give it or not. If it should be Ok then what should be the dosage? Please reply me.
