Lymphoma commonly develops in lymph nodes and lymphoid tissues and is associated with malignant changes in immune cells during the immune process, and is a malignant tumor of the immune system. The initial stage of lymphoma commonly includes swollen lymph nodes, lymph node compression on peripheral tissues, and systemic symptoms, etc. There may not be too many precursors before the onset of lymphoma, and the disease may have already occurred when symptoms appear, so there is no such thing as the top 10 precursors: 1. Swollen lymph nodes: The initial common symptom of lymphoma is painless swollen lymph nodes, and the common sites are lymph nodes in the neck, clavicle, armpit and groin. There may be a swelling sensation at the onset site and a cartilaginous sensation when touched, and usually the lumps are movable. 2. Lymph node compression on peripheral tissues: pain may be produced by nerve compression of enlarged lymph nodes, and abdominal masses may lead to abdominal pain and other symptoms. Pain or functional limitation of surrounding tissues or organs are common in other parts of enlarged lymph nodes, such as hoarseness and dyspnea; 3. Systemic symptoms: Patients with Hodgkin’s lymphoma commonly have generalized fever, itching and wasting. A few patients have periodic fever symptoms, and some patients will be accompanied by lymph node pain after drinking alcohol. Patients with non-Hodgkin’s lymphoma may develop generalized fever and emaciation in advanced stages of the disease. In addition, some patients may have anemia, abnormal digestion, poor appetite and other symptoms; 4. Other: a small number of Hodgkin’s lymphoma patients may develop herpes zoster. The location of tumor in non-Hodgkin’s lymphoma patients may be systemic, and the incidence will gradually increase with age.
