Hi Krishna,
Sorry to hear about your Dad. How is he doing after the surgery.
I have to agree with lot of people here regarding chemo with radiation is the best bet right now to avoid all future complications from this stupid disease. I will certainly get second openion from another care facility.
I am from Hyderabad,AP and they do have a good facility there. Hope I can help you further, give me a call. My number is in your private messages inbox.
thanks
Praveen
