Sardarsing you are assuming that just because the tumor operation is successful for other races and countries that it will be successful on the Nepali. In Nepal the tumor is deep within the brain that if you remove it, either few of your body parts might not be working, or you might get paralyzed. The chance of full recovery is very low. So you might want to reconsider surgery right now, and try to eat healthy, get lot of oxygen, maybe try some herbal medicines or accupunture. Wait and see for a little while before you jump into the operating table.
