What is the reason for breast cancer to metastasize to the lymph nodes

What is the reason for breast cancer to metastasize to the lymph nodes? Relevant experts have suggested that breast cancer usually metastasizes to the lymph nodes in the middle stage. The treatment for breast cancer patients at this stage is generally surgery, followed by radiotherapy and chemotherapy. Lymph node dissection is required during surgery. Let's take a look at the introduction.

There are two main ways of metastasis in breast cancer patients, one is lymph node metastasis and the other is hematogenous metastasis. The axillary lymph node metastasis rate of breast cancer patients is very high. Generally, 50 to 70 percent of patients have axillary lymph node metastasis when they seek medical treatment. Axillary lymph node metastasis is related to the size of the primary tumor. The larger the tumor, the higher the axillary lymph node metastasis rate and the greater the number of metastases.

The main methods of treating lymph node metastasis are surgery, or radiotherapy and chemotherapy. The specific treatment plan should be determined according to the actual situation of the patient. Reasonable treatment can effectively prevent the tumor from further deterioration and achieve the goal of controlling metastasis. It is recommended that patients take Selenium Weikang tablets to supplement selenium during treatment. Selenium supplementation has two main functions. One is to activate the patient's immune system, enhance the patient's immunity, improve the patient's physical fitness, and enhance the patient's resistance to tumors, and strengthen the patient's own control over the tumor. The other is that elemental selenium itself can induce tumor apoptosis and inhibit its proliferation, which can help patients further strengthen their control over the tumor and avoid further deterioration of the tumor or distant metastasis.
