Right breast hypoechoic nodule, if the boundary is clear, the internal echogenicity is homogeneous, the axillary lymph nodes are not enlarged, and the grading is grade 3 or below, it is considered to be breast fibroadenoma. Fibroadenoma is a benign disease and is not serious. It requires surgery if it exceeds 2 cm, but can be observed regularly and reviewed every 6-12 months. If the boundary of the hypoechoic nodule is unclear, the internal echogenicity is not homogeneous, accompanied by enlarged axillary lymph nodes, and the grading is above grade 4, it is more likely to be breast cancer, so it needs to go to the hospital for surgery in breast surgery and rapid pathological examination during surgery. If there is distant metastasis, radiotherapy, chemotherapy or targeted drug treatment is needed, and then the possibility of surgery is determined.
