[|Human|] I once had a pre cancerous bit of skin removed on my chest area just below my collar bone. there is a minor scar there. but just yesterday I noticed a lump and pain near that area under the skin. what should I do or better yet, who should I go to to check this out a primary care physician or a dermotologist?
[|AI|]  Hi. Thanks for your query. Noted the history and understood your concerns. The scar due to surgery for precancerous lesion on chest below clavicle can be enlarged due to the following reasons:Hypertrophied scar, Keloid formation. Recurrence of precancerous or cancerous lesion. I would advise you the following:As asked by you, meet/consult the Surgeon who operated you. Needs clinical evaluation and examination. The further management will depend upon the actual diagnosis and may need high resolution ultrasound and FNAC that is fine needle aspiration cytology. If this is a hypertrophied scar or a keloid, treatment is conservative and can be application of anti-scar ointments, local steroid injection. If pre cancerous or a cancer then needs wide local excision, send for histopathology and further management as per the reports.
