Tests and diagnosisBy Mayo Clinic staff Based on information you
provide to your doctor and the results of a physical exam, you
might need to have additional tests, which may include: -
Diagnostic ultrasound of the nipple and areola. An ultrasound
uses sound waves to make images of breast tissue. It allows your
doctor to evaluate the milk ducts beneath your nipple. A
diagnostic ultrasound lets your doctor focus on an area of
suspicion. - Diagnostic mammography. Mammography provides X-ray
images of your breast and can help your doctor evaluate your
breast tissue. A diagnostic mammogram provides more detailed
views of a specific area of your breast than a screening
mammogram does. - Non-cancerous breast conditions. American
