Eshwar- I disagree with you on this. No one but the pathologist is going to put a "for sure" label on it. He is only going to do that when looking at a tissue sample under a microscope. ONLY in very advanced disease, could someone look at something and say yes that is cancer. (Then even my gardener could tell you its cancer.) Perhaps in your country there are lots of those very advanced cases finally getting to a doctor to be seen (Like you see pictures of on so many web sites from your country). Here in the US, even with late staging, the physical manifestations can be very ambiguous. Biopsy is the only means to know for sure. Please do not take this as any kind of slander to the medical situation in your country.
