<s>[INST] Hi My baby has a small lump on his chest. when he was born i noticed a tiny hole and when we talked to the GP he said its nothing to worry about but now there is a lump in place of the hole and soft when pressed and kinda like jelly. he is not in any pain but am concerned what does this mean [/INST] Hi, welcome to Chat Doctor. I see similar cases in my clinic every day. During prenatal period sometimes maternal hormones like estrogen pass in baby which causes swelling of breasts on 3 or 4th day, a white creamy liquid may also ooze from the nipples. Usually, no treatment is required. Engorged breast should not be pressed, massaged or squeezed since this may result in infection. I hope this has helped you. Take care. Regards - Chat Doctor.  </s>
