Figure 1 HER2-enriched invasive cancer. A: High-risk microcalcifications on mammogram of the left breast are seen within the palpable mass (denoted by triangular skin marker); B: Irregular hypoechoic mass showing increased internal vascularity (Adler Index Grade III) and internal echogenic foci representing microcalcifications.

Figure 2 Triple negative breast cancer. A: Circumscribed mass on mammogram; B: Circumscribed hypoechoic mass with posterior acoustic enhancement on ultrasound.

Figure 3 Luminal type invasive cancer. A: Spiculated mass on mammogram; B: Irregular hypoechoic mass with spiculated margin and posterior acoustic shadowing.
