I have had cancer removed on my right hand by amputation of middle finger in 2015.  Now I have a mass under my  arm pit with a Large marble that moves and is painful.  I had blood work awaiting results/waiting until the MD office sets up a CT scan.  Should I be concerned? How long is to long to wait for tx?
Hello, The painful lump in armpit can be inflammatory origin from preexisting boil or metastatic lymph node with secondary changes. Must wait till the results of reports come, the diagnostic tool would be Fine needle aspiration cytology or excision biopsy of the lump. Hope I have answered your query. Let me know if I can assist you further.
