Breast ultsound reports a prominent lymph node 7mm on short axis, retains normal echogenic hilum, prominent retroareolar duct. What follow up is needed?

Why did you get one. At your age mammograms are not recommended unless you have a high risk to develop breast Cancer. So tell us the history and what did your doctor advise you to do next? From my perspective, I do not find these changes alarming. Recheck with mammography is discretionary depending on your family history and risk factor/s.
