My mom had a lumpectomy and had 3 lymph nodes removed on her left side in 2008. She also had radiation for that breast. In 2013 she had mastitis and was hospitalized, given vincomyacin introvinusly for a few days. Infection cleared up then she had a sty a few weeks later on left eye. She was given antibiotics and that cleared up. Now my mom is almost 92 and for the past 2 months has had a red, swollen breast again on the same side. We did a month of vincomyacin again and 5 days of cutaninr? Not sure of spelling. It is no longer warm however it is very red and swollen. Punch biopsy proved no cancer. Help me please.
