Thyroid and breast refer to the thyroid and the breast. In many tertiary care hospitals, due to the refinement of disciplines, there is a special thyroid and breast surgery department, referred to as the thyroid and breast surgery department, which mainly treats benign and malignant space-occupying lesions of the thyroid gland, as well as breast tumors, etc. These are all superficial lesions that can be diagnosed by local color ultrasound examination. Details include nodular goiter, simple thyroid adenoma, and thyroid malignant tumor, while breast diseases include breast hyperplasia, breast cyst, breast fibroma, lipoma, and breast malignant tumor. The malignant tumors of the breast are further detailed into breast cancer, specific to many types of pathology, as well as sarcomas of the breast, and inflammatory breast cancer, which is very malignant. Eczema-like breast cancer of the nipple, also known as Peyer’s disease of the breast, is a relatively early malignant tumor, and the most effective treatment for malignant tumors is to opt for radical surgery.
