Patients who meet all three of the following criteria are good candidates for SBU:
- Negative mammogram within the past six months
- Dense breast tissue identified on mammogram (category C or D)
- One or more of these risk factors:
- Personal history of breast or ovarian cancer
- Family history of breast cancer
- History of breast biopsy showing atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), lobular carcinoma in situ (LCIS) or other atypical pathology
In addition, a patient may opt for SBU if she is a candidate for breast MRI (magnetic resonance imaging) but is unable to have an MRI for financial or other reasons, including claustrophobia, contrast contraindication or metal/devices precluding MRI. Please note that patients who have had a recent breast MRI or are eligible to have one in the near future do not need to also have an SBU.
Screening ultrasound causes no significant physical discomfort. SBU does not require injections or breast compression, and no advance preparation is needed. A breast ultrasound technologist or a physician will perform the scan of the entire breast using a hand-held ultrasound probe. The appointment can last up to 60 minutes. Patients will receive results before leaving, as well as information about any additional tests that may be indicated. Patients can resume normal activities immediately following SBU.
