LOL Everyone is entitled to his own opinion... that does not make it correct! Although, with GungFu a part of traditional Chinese medicine, it is possible that some of the great GungFu masters know better than some of the worst doctors... BUT, it is deceptive to pretend that the average martial artists know the human body better than the worst doctor! Osu!
at this point you have to verify the doctor's diagnosis and course of action with a second opinion. if they are right and you do have to stop but don't want it comes down to the usual thing that we face everyday: "what are you going to do about it?" 1. ignore the doctor and hope for the best. 2. stop. 3. get operated on and hope for the best. 4. keep going as if nothing happened.
