hi, my father,47, underwent carcinoma left floor of mouth in june,2012 and operation, all d chemo and radiation therapy have been completed.He is examined under TATA MEMORIAL CENTRE. But he is having cough right now. Doctors suggested X-ray for precaution reasons, but nothing came up in X-ray report. So, they did CT-SCAN OF THE CHEST in which it is written LESIONS IN LUNG MAY REPRESENT METASTATIC DEPOSITS. and after this, they have also done needle biopsy. It s report is yet to come. what can u conclude about it?
