[|AI|]  Hi, Thanks for writing in. Any cough in a patient that is present for more than two months and is not responding to treatment is a sign of chronic disease. In India such non resolving cough is likely to be due to tuberculosis or cancer unless proven otherwise. The first step in evaluating such a condition is by doing an X-ray chest and looking for any signs of disease. If there is any suspicious area then it requires that a CT scan of chest be done. This is a detailed investigation and shows problem areas which are small in detail. Any finding in X-ray or CT scan should be evaluated further by doing tests like bronchoscopy or biopsy if required. Confirmation of diagnosis whether it is TB, cancer or anything else is certain after doing a biopsy. Since you have got a biopsy done for your father, you have to wait for the report to know final diagnosis. Biopsy is a skilled technique and if the area of biopsy is small or the cells have not come properly then repeat test is required. Please get an X-ray done if your father still complains of chest pain after the biopsy. Any complications of biopsy need to be ruled out. Please do not worry.
