Is breast cancer metastasis to one lymph node considered spread?

Is breast cancer metastasis considered spread if it metastasizes to one lymph node?

1. Generally speaking, breast cancer metastasis to one lymph node is usually considered spread. Breast cancer metastasis to one lymph node refers to breast cancer accompanied by lymph node metastasis, which is more serious.

2. Breast cancer is a phenomenon in which breast epithelial cells proliferate uncontrollably under the influence of various carcinogenic factors. Early stage diseases often present with symptoms such as breast lumps, nipple discharge, and enlarged axillary lymph nodes. In late stage, cancer cells may metastasize to distant sites and cause multi-organ lesions, threatening the patient's life.

3. Breast cancer with lymph node metastasis is considered spread and more serious, because once breast cancer is accompanied by lymph node metastasis, it is often not early breast cancer. In the international breast cancer TNM staging standard, breast cancer with lymph node metastasis is at least stage II breast cancer and needs more active treatment methods. For example, after radical surgical resection of breast cancer, if ipsilateral axillary lymph node metastasis is confirmed, postoperative adjuvant radiotherapy should be performed after postoperative adjuvant chemotherapy. It can delay the recurrence time of breast cancer patients after surgery and prolong the survival of patients.
