A strongly echogenic breast spot is a locally formed strongly echogenic spot-like lesion suggestive of calcification on ultrasound examination of the breast. They are usually caused by breast hyperplasia, postoperative changes in the breast, and breast cancer. 1. Mammary hyperplasia is a common benign lesion of the female breast, usually associated with endocrine disorders. When breast hyperplasia occurs in women, after a long period of time, fibrosis will occur in the area of breast hyperplasia, which will be manifested as calcified spots, so that localized strong echogenic spots can be seen in ultrasound examination. 2. After breast surgery, there may be localized scar formation after the surgery, which may be manifested as strong echogenic spots, which is also a benign sign. 3. Breast cancer may occur. Breast cancer often occurs in middle-aged and old women, and usually has the malignant sign of tiny calcification. Therefore, in addition to ultrasound examination, tumor marker screening and genetic screening can also be used to assist in the diagnosis of breast cancer, and once diagnosed, it is necessary to standardize the treatment in a timely manner. Strongly echogenic light spots in the breast may also be caused by breast trauma, breast inflammation and other causes of calcification, patients should consult the doctor in time and follow the medical advice.
