<s>[INST] Im a 17 year old girl, 50, around 110 pounds. I have a cyst of the skin on my right breast. Ive been to my doctor, who prescribed me medication (Augmentin), but the lump just got bigger, more painful and red. After a sonogram, she told me to continue with the antibiotics and Im scheduled to see her in two weeks. If the cyst persists, Im told I have to get it removed. However, recently, the skin on and around it started to peel, and I think I may have broken the skin because it started to bleed, and what looked like pus and an pily substance came out as well. Most of it has stopped, although I put a bandage on it if it continues. Should I be worried or is this sommething that just happens? [/INST] Hi, dairy have gone through your question. I can understand your concern. You may have some inflammatory cystic lesion in your breast or may be abscess formation.  You should complete the course of antibiotics. If it doesn't respond to treatment then you should go for biopsy, and then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
