The thickening of echogenicity of breast glands is mainly suggestive of breast hyperplasia and inflammation of the breast. 1. Mammary hyperplasia: Mammary hyperplasia is often characterized by uneven enlargement of the glands, which is often indicated by thickening of echoes on breast ultrasound. Clinically, the severity of breast hyperplasia can be roughly judged according to the degree of thickening shown by ultrasound. Breast hyperplasia is usually related to the menstrual cycle of women, and the diagnosis should be made according to the specific pain condition of the patient. 2. Breast inflammation: If there is inflammation in the mammary glands, the ultrasound may also show thickening of the echogenicity of the glands. At this time, the blood flow signal on ultrasound is often significantly enhanced. The patient is also often accompanied by local skin redness, swelling, heat and pain and other general signs of inflammation. It is recommended that patients under the guidance of a regular doctor, according to their own specific symptoms, to carry out further examination to confirm the diagnosis of related diseases.
