The diagnosis of bladder tumours
The commonest presenting symptom of a bladder tumour is haematuria, which may be repeated but frequently occurs on one occasion only. In males over the age of 40, about half the cases are due to neoplasm. It is therefore obvious that haematuria, however slight, should always be considered seriously. Thus the first essential in diagnosis is the proper investigation of all cases of haematuria. This phase is usually the responsibility of the general practitioner.
