A small bump that has stayed about the same for two weeks, without pain or quick growth, is most often a benign skin issue like a blocked pore, small cyst or ingrown hair sitting on the skin rather than a true lump inside the breast tissue.
Next Steps
Keep the area clean and dry, wear loose cotton clothing, and avoid picking at it. If it keeps growing or changes, please see a gynaecologist for an in-person look.
Health Tips
See a doctor sooner if it turns hard, red and spreading, or starts discharging, since that can mean an infection.
