Symptoms

Breast changes that may occur:

  • Breast lump or irregularity
  • Breast tenderness , swelling, or increased warmth

Changes in the shape of the nipples may include:

  • Inverted nipples, in which the nipple is indented into the areola, but will often come out with breast stimulation or during pregnancy
  • Retracted nipples, in which the nipple was raised above the surface but begins to pull inward and does not come out when stimulated

Nipple discharge may be:

  • Milky (galactorrhea)
  • Clear, bloody, or discolored (green or brown) discharge
  • Present only with pressure on the breast or without pressure (called spontaneous discharge)
  • Present in one or both nipples

Skin changes around the nipple may include:

  • Redness, tenderness, and cracking of the skin surface of the nipple
  • Dimples, puckers, or a rash on the skin of the nipple or the areola (darker skin that surrounds the nipple)

Signs and tests

The health care provider will take your medical history and perform a physical examination.

Tests that may be done to look for causes of nipple discharge:

  • Prolactin level
  • Thyroid function tests
  • Head CT scan or MRI to look for pituitary tumor

Other tests that may be done include:

  • Mammography , performed in all cases
  • Ultrasound of the breast
  • Breast biopsy if a mass or lump is found, if the mammogram is abnormal, or if the discharge is occurring on its own without any pressure on the breast
  • Ductography or ductogram, an x-ray with contrast dye injected into the affected milk duct
  • Skin biopsy , if Paget's disease is a concern
