[|Human|] Hi, may I answer your health queries right now ?  Please type your query here...  My sister has a hard lump in her breast that hurts her & she said she where the knot is, its reddish pink on top of it.  My sister is 41 years old and over all in good health - could this be a cyst or is it cancer?? Thanks for any advise.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. She has bread lump and it is hard.  So it can be breast cancer, fibrotic disease or fibroadenoma.  She should go for examination, mammography and biopsy of breast lump.  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.
