If a mass is found in the breast gland, a specialist examination should be performed to further clarify the location, size, margin and pain level of the mass. The common tumors are benign tumors, which are influenced by changes in hormone levels in the body, and should be promptly examined by color ultrasound of the breast, including cystic hyperplasia, fibroadenoma, and lipoma of the breast. In addition, if there is an irregular mass in the breast gland or if there is obvious vasodilation in the breast skin, malignant tumors are more likely to occur and should be surgically removed in a timely manner, and if confirmed to be malignant, expanded excision should be performed, and if necessary, axillary lymph node dissection should be performed. The occurrence of malignant tumor may also be affected by endocrine, and endocrine therapy should be performed if necessary.
