instruction: hello doctor I have a lump behind my left nipple for around 10 years it is a painless and hard lump which is just behind the nipple and it seems to be round in shape and is about more than am in size it is not growing and is of fixed size I also notice skin discoloration on the breast like slight melanin patches I also notice a few minor or very small fluid lumps in the right breast area please tell me if the lump can be cancerous
output: hello it looks all these lesions are benign non cancerous this small lump which is there for 10 years is certainly benign as cancerous lump grows and spreads regarding skin discoloration looking like melanin patches and fluid lumps you have not mentioned the details regarding discoloration and fluid lumps whether they are new or old whether they have increased in size as compared to the previous one or whether they have shown any change in appearance etc nothing to worry about but it is recommended to visit a mammalogist and let them examine all these breast and skin lesions if needed they will put you on close follow up or investigate further the major risk factors for developing breast cancer are family history of breast cancer obesity certain genetic syndromes any previous breast lump hormone replacement therapy history of estrogen intake early menarche or late menopause in case you have any family history of breast cancer then you must go for genetic counseling also
