Hello, I discovered a hard lump on my left collarbone a month ago.  It is now big enough that you can visually see it.  I also feel like my throat is swelling or getting smaller. I was diagnosed with Rhumatoid Arthritis 5 years ago and have been in Enbrel ever since. Im obviously worried about lymphoma. I dont have any other strange symptoms..Im a 50 year old female.
Hi, In most cases this is just a swollen lymph node which doesn't require any specific treatment. Also, considering your description this may be some other benign subcutaneous lesion such as lipoma, fibrous or atheroma and if there are no skin changes such as redness, pus discharge or pain and fever then you should not be worried since it can be easily surgically removed under local anesthesia. Then it there is doubts it can be sent to the patohistologic analysis.  Hope I have answered your query. Let me know if I can assist you further.
