What is a hypoechoic nodule in the breast area?

Radiology term: That is a radiology term for a lesion that blocks ultrasound waves and makes a shadow on the ultrasound image. Sometimes correlates with denser tissue such as in malignancy in breasts. Your doctor can review the report with you.

Cyst/Solid Nodule: This is a term used to describe certain breast lumps seen on ultrasound. In and of itself, this is not very descriptive. Further ultrasound information can help us determine if its a cyst, a benign tumor, or suspicious of a malignancy (irregular margins, "taller than wide", vascular), in which case biopsy will be recommended.

Ultrasound finding: You are describing an ultrasound finding of the breast. A hypoechoic nodule refers to a dark lesion seen on ultrasound. You would need more information to determine whether the lesions was benign or malignant.
