My father(age-50yrs, height-6 feet, weight- I don't know, medical history- victim of piles) has a wound in his food pipe.Because of which his stomach is fattening,without eating anything(he does not feels hungry ). And a specimen of some part has been sent to Mumbai for diagnosis(byopsis). And we are afraid that diagnosis may lead to cancer. So, I wanted to know can this be a cause of cancer to any extent?
