Lymphatic metastases are the most common site of breast cancer metastasis, and axillary lymph nodes are infiltrated and are surgically removable.
Breast cancer can be broadly divided into two types: carcinoma in situ, as the name implies, mainly involves the lobules, and the cancer cells are confined to the ductal vesicles without penetrating their basement membrane.
The most common form of breast cancer metastasis is lymphatic metastasis, which is mainly due to the lymphatic surroundings of the breast, where the cancer cells are shed and metastasize with lymphatic fluid.
First, axillary lymph node metastases can be resolved surgically, and second, systemic treatment with chemotherapy can be added after surgery.
The specific treatment plan can be chosen according to the pathological results. At present, whenever axillary lymph node metastasis occurs, systemic chemotherapy and local radiotherapy are required, and as long as the treatment is standardized, the treatment effect is now considerable. The patient’s specific condition requires a customized treatment plan.
