Hi. I am a generally healthy 38 year old male. I have a hard lump in my left armpit on the side of the chest. I  sometimes experience a dull pain that feel as if it extends into the muscle. My GP recommended that I see a surgeon, but army doctors tend to cut everything out! What could it be and isnt there another option that surgery? Thank you.
Hi. Thanks for your query. The best alternative way is to have FNAC, meaning fine needle aspiration cytology examination under ultrasonography guidance is possible. This can give a positive finding. You may need surgery only if the FNAC is not conclusive and needs to be excised It will be very difficult to say what has caused this swelling. It may be a lymph node or sebaceous cyst. If this is a sebaceous cyst, it has to be removed.
