<s>[INST] Hi im 18 and last night i just noticed a small hard painless lump on my right breast. its very small. i just noticed it which means its very recent like it just showed up in the past couple days. What do you think it might be. Im extremely scared. Please Help [/INST] welcome to Health care magic.1.No need to get scared, its not the age to worry about the lesions in the breast.2.You are giving a very short history since you are seeing that lump.3.Generally in few cases this kind of symptoms are seen, they turns up as dilated ducts or focal dilatation.4.More over you wait for a week, if its asymptomatic, and feel again - Then see your doctor.5.An ultrasound scan will help to evaluate what its and what it contains.6.Hope it helps. Anything to ask ? do not hesitate. Thank you. </s>
