My father aged 65 years has been diagnosed with rectum cancer with liver metastases on both lobes on 5th January 2017. He had weight loss of around 8 kgs since feb 2016 but at that time, he was diagnosed with diabetes. Since last couple of months, he was suffering from constipation which had some blood passing through stool couple of times. Currently his weight loss is under control & initial opinions based on biopsy & ct scan reports suggest that he cannot be operated but chemotherapy is the only solution. We are open for allopathic / ayurvedic as well as homeopathic treatment. please advice.
