Lymphoma is a malignant tumor that originates from lymph nodes or lymphatic tissue. If it occurs in the axillary area, it is called axillary lymphoma. There is no clinical statement of the ten precursors of axillary lymphoma. When axillary lymphoma appears, patients may have local symptoms, systemic symptoms, etc. 1. Local symptoms: Patients may show symptoms of abnormal enlargement of axillary lymph nodes, which are usually hard, elastic and can be pushed without pain, and the swollen lymph nodes will gradually increase in size over time. In addition, if the lymphoma suffered by patients is Hodgkin’s lymphoma, some patients may show pain at the tumor site after drinking. 2. Systemic symptoms: Some patients may show symptoms such as fever, fatigue, night sweats, itchy skin, emaciation, pain and numbness in upper limbs. Fever may be continuous or periodic, or intermittent low fever, usually at 38-39℃. Weakness, on the other hand, is often felt as a lack of energy and physical fatigue in life. Symptoms of night sweats often appear at night, or after going to sleep. Itchy skin can appear locally or all over the body, and is generally more common in young women. In addition, wasting usually refers to weight loss of more than 10% within 6 months; 3. Other symptoms: Due to the enlargement of lymphoma, some patients may have some uncomfortable symptoms due to its compression, such as compression of surrounding blood vessels, which may affect blood circulation. Compression of nerves may cause pain, swelling, numbness and other conditions. If the above symptoms occur, patients should be alert to whether axillary lymphoma has occurred. Patients are suggested to go to the hospital in time, and under the guidance of doctors to conduct ultrasound, CT, as well as biopsy of lymph nodes and other examinations, and after clear diagnosis, they can adopt surgical removal, or adjuvant radiotherapy or chemotherapy and other treatments according to the size of the tumor.
