Any surgery involves detailed study of a patient. Your doctor would ask you all possible questions about your lifestyle, eating habits, ailments, medications etc. before surgery. Always inform your doctor about any drug allergies or medical ailment or previous surgeries. He would also advise you particular tests that may be required depending on your condition and the type of surgery required. Once all that has been decided you may also want to zero down on a good hospital as advised by your doctor and ask the hospital for cashless facilities available.
