Is enlarged lymph nodes under the armpit a sign of metastasis in breast cancer?

Is enlarged lymph nodes under the armpit caused by breast cancer metastasis?

1. Swollen axillary lymph nodes may be caused by metastasis, but it may also be caused by other factors, which needs to be confirmed through examination.

2. Breast cancer is a malignant disease, mainly caused by the genetic mutation of breast cells to form malignant proliferation. Usually, when cancer cells proliferate locally to a certain extent, they will metastasize along with the blood circulation and lymphatic system. If cancer cells metastasize to the lymphatic area, secondary lymphoma will form after lymphatic proliferation. At this time, it may manifest as swollen lymph nodes, which is a common cancer cell metastasis.

3. Lymph node enlargement in breast cancer patients is not caused by cancer cell metastasis. If no cancer cells are found in the patient after lymph node biopsy, this is mostly local infection or lymphadenitis. Related diseases will stimulate the human immune system, and lymph node stimulation will cause swelling. Patients can use antibiotic drugs to treat breast cancer and improve the condition, such as amoxicillin capsules, azithromycin tablets, etc.

4. If breast cancer patients detect the disease in the early stage and undergo surgical treatment as soon as possible, most patients can achieve clinical cure. If the disease continues to develop and metastasize, the disease cannot be effectively treated and may even endanger the patient's life.
