A single dominant lump that is present for several months likely requires excisional biopsy. Single dominant cysts may be aspirated in an outpatient setting. Cytopathologic examination should be conducted if the fluid is bloody. Fibrocystic changes are histologically classified into the following three categories:

  • Nonproliferative changes
  • Proliferative changes without atypia
  • Proliferative changes with atypia
