Early signs of axillary lymphoma include obvious enlargement of axillary lymph nodes, hard texture of the swelling, mild pain, or unexplained fever, or no obvious clinical symptoms. Axillary lymphoma is usually categorized into primary and secondary. 1. Primary axillary lymphoma It is usually malignant lymphoma, and in the early stage when the tumor is relatively small in the early stage, so there are no obvious symptoms. A few people may have the symptom of a lump in the armpit, but there is no pain. If axillary lymphoma metastasizes, it may cause fever or symptoms of itchy skin and swollen lymph nodes. 2. Secondary axillary lymphoma It generally refers to the metastasis of tumor in other parts of the body to lymph nodes. Lymph node metastasis of malignant tumors is a common metastatic pathway, and cancer cells can migrate to other parts of the body with the blood or lymph circulation throughout the body. In the early stage after cancer cells have metastasized to lymph nodes, patients may have symptoms of obvious enlargement of lymph nodes, hard texture of the swelling and mild pain. Axillary lymphoma can be treated with chemotherapy or radiotherapy, or if the tumor has not metastasized, it can also be treated with surgery and the nearby lymph node clusters can be cleared at the same time. If you are found with axillary lymphoma, you should go to hospital for examination and treatment in time to prevent the disease from deteriorating and threatening your life and health.
