Whenever anybody goes to doctor he makes diagnosis in fraction of seconds and treats the patient. This so called Godly behaviour is supported by sheer hard work by the doctor during his school/ college days and afterwards. To split the methodology in various parts...Doctors minutely listens to what patient says. Hears every word. ( Many a times he may not look attentive). His eyes are scrutinising the general health of the patient when he is intently palpating the pulse of the patient. ...There could be dozens of signs which a experienced doctor monitors in fraction of second. His senses are tuned over a period of time to note the deviation from normalcy. He forms differential diagnosis in his mind. To rule out certian suspicions and confirm the abnormal impressions, investigations are advised.
Decision of Final treatment depends on history told by the patient, Clinical examination and Invetigational findings.
Decision of surgery is given after lots of analysis.
Diagnosis of Cancer is not informed to anybody unless confirmed by the study of cells called Histopathology examination.
This is called practice of Modern Medicine which we commonly label as Allopathy
