When the tumor is identified, your doctor may recommend a biopsy to identify how advanced the cancer is and how severe it is. A tumor is a mass of abnormal tissue.

Ultrasound is an essential breast imaging tool. Initially, the role of breast ultrasound was solely to distinguish cysts from solid masses. However, with major advances in ultrasound technology during the past 20 years, ultrasound can also now distinguish benign and malignant solid breast masses. PURPOSE: To investigate the general applicability and interobserver variability of ultrasonographic (US) features in differentiating benign from malignant solid breast masses. MATERIALS AND METHODS: One hundred sixty-two consecutive solid masses with a tissue diagnosis were reviewed. Three radiologists reviewed the masses without knowledge of clinical history or histologic examination by:
