WebJul 8, 2024 · Breast lumps can result from: Breast cysts. If you find a breast lump that feels round, smooth and firm, it could be a cyst — a dilated milk duct filled with fluid. A breast cyst can be large or small, and the surrounding breast tissue may be tender. A breast cyst may appear before your menstrual period and get smaller or disappear afterward. rberrios wtcmiami.org https://reliablehomeservicesllc.com
