All facilities but I did not get satisfied after 2. Review on Himalayan Institute Hospital - Dehradun

My mother has cancer I am doing her treatment there since 2014 but nothing happens. We had operation of cancer july 2014 and afterwards like doctors provided chemo, and radiation therapy and taking medicine every day since then and having injections like they said that time but suddenly once they are saying it's returned and more then before and avoiding to give answers properly there is not one doctor they are changing them like clothes some days before were someone now someone I don't know that they they are doing treatment carefully or not. Because when I applied for my insurance and they asked for some test papers which doctors didn't give us to do and they(insurance) are saying without this paper this doesn't approved. So how the doctors are doing treatment? When they asking for wrong tests.? When I asked to doctors they are just saying that doctor may have given you that test I didn't satisfied. But I have no choice it is only hospital for this treatment in my reach. I don't think that doctors are doing something wrong but I am saying that they are not talking serious and much carefully like they should be and just doing like their duties. And doctors are not same then only patients got troubled and in suspect.
