Hi, first thing required is the diagnosis, it may be secondary metastatic grouth from a distant organ, or there may be an abscess
in the breast, which burst in side the breast. I to my patient with such symptoms prescribe antibiotic, and protiolytic, and styptics.
I advise you to consult a cancer specialist with all facilities for investigations, you may need to have biopsy
of the small lump behind the nipple.
