<s>[INST] So I had had this black thing on my one of my breast. It seemed like a pimple but it was black and i would like try to take it off, and it wouldnt. Yesterday I accidently scratched it and it fell out and left a small hole, could it be something relating to cancer? [/INST] Hi, dairy have gone through your question. I can understand your concern.  From your description it doesn't look like cancer.  It may be some cyst or abscess.  No need to worry. Just be relaxed.  You should go for biopsy of that lump once.  It will give you exact diagnosis. 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>
