Hi, Welcome for your query to Chat Doctor. Your smoker friend has only 1 week complaint of severe Constant Chest Pain. Based on the query information,2 yrs back X-ray chest was normal. If chest pain is the single complaint, I would rule out the Infective causes for such a lump after review of the Chest X-ray. I would advise CT/PET Scan to study more details of the lump in the right lung. Till you have definite study of the lung lump with Oncologist, who would examine all the aspect of lung lump, You should not carry any anxiety from such a painful lump in the lower lung, unless proved by HPR of the lump biopsy Flexible Bronchoscopy Under CT/PET Guidance or HPR study of the Bronchial lavage from the nearby bronchus on flexible bronchoscopy. Plan of assessment--If the lump remains or increases even after Antibiotic course for 10 days time, I would not label as a Cancerous lump of the lung blindly. So till then close this fear of Cancer, that would be my advice. Hope this would help you to plan treatment with your doctor. Will appreciate your review write up and hitting thanks, to help needy patient visitors like you at Chat Doctor. Welcome for any further query in this regard. Good day!! Chat Doctor. N.
