A breast ultrasound involves lying on a table while a hand-held device called a transducer is moved over the skin of the breast, creating a picture on a screen.
A breast ultrasound is an imaging technique used to look at tumors and other breast abnormalities. The ultrasound uses high-frequency sound waves to produce live images of the inside of your breast.

Unlike X-rays and CT scans, ultrasounds use no radiation and are considered safe for pregnant women and nursing mothers.

A breast ultrasound will be performed if you or your doctor discovers a suspicious lump in your breast. The ultrasound helps determine the location and size of the mass.

  • Preparation for a breast ultrasound is minimal.
  • You don't need to be fasting.
  • No ions, or other cosmetics on the skin of your breasts. This can interfere with the test procedure.

The majority of breast lumps are noncancerous and mostly Ultrasonography alone is useful to diagnose following benign conditions especially if mammography is not useful below age of 40.

  • Fibroadenoma: a benign tumor of the breast tissue with distinct margins
  • Fibrocystic breast disease: painful, lumpy breasts caused by hormone changes, which appears as fluid filled sacs
  • Intraductal papilloma: small, benign tumors of the milk ducts
  • Mastitis or abscess: lumps with collection of pus

If your doctor finds a mass that requires further testing, he or she may order an FNAC or biopsy that may be performed on the same day. During the procedure, your doctor may use an ultrasound to guide the biopsy needle
