52-year-old female. Right breast cancer status post 3 cycles of chemotherapy. Reevaluate size of tumor. A targeted right breast ultrasound was performed for the patient's known breast cancer at the 9 to 10 o'clock position, 1 to 4 cm from the nipple. The larger, more anterior component of a heterogeneously hypoechoic mass containing a biopsy clip measures 2.7 x 2.4 x 3.0 cm, previously 3 x 2.8 x 3.4 cm. Posterolaterally, the smaller component of the mass at the 10 o'clock position measures 1.7 x 1.1 x 2.1 cm, previously 1.7 x 1.7 x 1.9 cm, slighty decreased in size. An enlarged right axillary lymph node containing a biopsy clip measures 2.2 x 2.3 x 0.9 cm, previously 3.3 x 2.8 x 0.9 cm.
Slightly decreased size of the patient's known right breast cancer and decrease of the biopsied axillary lymph node. If further imaging is needed, a follow up MRI is suggested. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
