Dotted strong echoes seen within a weakly echogenic breast nodule generally refers to ultrasound or CT examination, and is an imaging description, usually calcification, of a disease that is clinically prone to calcification within the nodule, mainly breast or thyroid nodules. If there is strong echogenicity and calcification in the breast, further grading of the breast nodule is usually needed. If it is grade 4 or above, it indicates some possibility of malignancy, and further mammogram is needed, with cytology if necessary, to rule out malignancy. If the diameter of the tumor is more than 2cm, it needs to be excised by local anesthesia, sent for cryoexamination, and diagnosed as malignant, requiring radical mastectomy for breast cancer. For calcification of thyroid nodules, further grading is also needed. Those graded more than grade 4 should be punctured and examined, and those more than 2.5 cm in diameter should be surgically excised and frozen intraoperatively. If freezing is reported as thyroid cancer, radical thyroid cancer surgery is required. The patient should go to the hospital for examination and treatment under the supervision of the doctor.
