Just had a followup 2nd mammogram and ultrasound due to dense breasts. Results of ultrasound are as follows: HISTORY: Follow-up dense breasts. Comparison is made to bilateral mammograms dated 01/20/2017 and 01/11/2017. Ultrasound the right breast was performed to include retroareolar region all four quadrants in the right axilla. There is a 1.9 cm right axillary lymph node. There is several scattered hypoechoic flattened appearing nodules in the right breast 9 mm at 12 o clock, mildly prominent duct at 3 o clock, flattened appearing 8 mm hypoechoic nodule at 3 o clock and a 3 mm cyst at 7 o clock. There is also a 3 mm retroareolar cyst. Ultrasound the left breast was performed to include retroareolar region and all four quadrants and left axilla. Flattened appearing 9 x 2 mm hypoechoic nodule at 12 o clock and 3 mm cyst at 2 o clock.
