[|Human|] I have a rash on my left shoulder area and a gel feeling lump at the middle of my collarbone.  I had Rotator Cuff Surgery on my right shoulder on 11/4.  I have a strong history of cancer.  Lung cancer in 2002 and bladder cancer in 2009 and many basal cell cancers.  I am concerned with these two symptoms.  Thank you
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You have rash on shoulder and lump in middle of collarbone with family history of lung and bladder cancer.  Your lump may be enlarged lymph node due to reactive hyperplasia, tuberculosis, lymphoma or metastatic carcinoma, or you may have some soft tissue tumor. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact idea. Then you should take treatment accordingly. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
