An ultrasound-guided breast biopsy is a minimally invasive breast biopsy that uses ultrasound guidance. We use a biopsy to determine if a mass we see within the breast is benign (noncancerous) or cancerous.

Ultrasound is an imaging tool that uses sound waves to produce images of breast tissue. A radiologist reviews these images and scans to distinguish various findings, looking for changes that may be as obvious as “masses” or as subtle as slight pulling of the tissue called “architectural distortion.” The findings on a breast ultrasound are often too small or deep to be felt on examination.

The best way for women to detect early changes in their breasts is to have regular screening mammograms, which often show areas of concern before they can be palpated during a clinical exam or breast self-examination (BSE). Further testing or a breast biopsy may be recommended if we discover a mass or architectural distortion during a screening.

For breast lumps that come and go with the menstrual cycle, it is reasonable for a premenopausal (before menopause) woman to observe a non-suspicious finding until after the next menstrual cycle. If the finding does not resolve after the next monthly cycle, then you should seek attention from your physician or dedicated breast imaging center. However, some women may present with serious breast complaints such as a fixed mass, skin change including thickening redness, nipple inversion, or bloody discharge is noted. If you experience any of these serious symptoms or signs, then immediate imaging workup is indicated.
