[|Human|] Just yesterday I realized I have a lump in the middle of my chest. Its right in between my breasts. It hurts when i press it and I even get pain in my back directly behind it sometimes. I did not have the lump before but that area did hurt starting last sunday and then I was even short of breath or whenever I would breath it would hurt, and the deeper I would breathe in the worse it hurt. Im not sure what is going on.
[|AI|]  Welcome to Chat Doctor .1. Lump with pain radiating to the back and shortness of breath seems like an infective etiology (bacterial infection - Abscess, infective cyst).2. If you are mu patient I would have examined and ask for the ultrasound lump / lesion. (helps in assessing the nature of lesion, its source and extensions)3. After that depending on the nature - an FNAC - fine needle aspiration cytology to evaluate the kind of cells (benign / malignant / infective)4. If infective a small incision and Chat Doctor. 5. If mass lesion - depending on extension removal will be planned. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
