[|Human|] I have a large lump behind my nipple on my left breast. It moves around and is about the size of a gumball. Sometimes my ribs right under that breast hurt. I am having the lump removed in a week, but am worried about cancer. It runs in my family. What do you think?
[|AI|]  Welcome to Chat Doctor .1.Don't worries its not always lump in the breast is cancer. There are many benign lumps and dilated ducts.2. To evaluate you need to have an ultrasound breast done which is good tool to evaluate exact content (mass, cystic, ductal dilatation).3. Hope you had all these done including FNAC/BIOPSY.4. Once removed you need to get followup at least 6 monthly since you have risk factors. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
