Hi Dr Ma I am 40 years old and my latest ultrasound report states: Multiple possible fat lobules or fibroadenomas in the breasts. The nodules with marked hypervascularity in L8/9H (1 x 0.4 x 0.9cm) of the breast is noted. Aetiology is uncertain. Follow up with mammogram and US 3 months' times is suggested. Bi-RADS 4. 咁係屬於category 4a, b or c? Hypervascularity 其實代表咩? 你建議需要抽針嗎? Thanks.
