How is lymphoma diagnosed?

Lymphoma can be diagnosed by a variety of tests, including physical examination, blood test, imaging test, pathological biopsy and bone marrow examination. The following are some common tests: 1. Physical examination: The doctor will conduct a comprehensive physical examination of the patient, including palpation of lymph nodes, liver and spleen, etc., to understand the superficial parts of the body. 2. Blood test: By detecting the number of white blood cells, classification, platelets and other indicators in the blood, as well as examining markers such as lactate dehydrogenase and β 2-microglobulin in the serum, to assess the overall health status and tumor burden.3.Imaging: Ultrasound: It can be used to examine superficial lymph nodes, liver, spleen and other parts to understand whether there are enlarged lymph nodes or other abnormalities. CT scan: CT scan of multiple parts of the body, which can more clearly show the location, size, shape and relationship with surrounding tissues. MRI examination: high resolution of soft tissue, can be used to examine brain, spinal cord, pelvis and other parts. PET-CT examination: Combined with positron emission tomography and CT technology, it can more accurately detect the metabolic activity and distribution of tumors. 4. Pathological biopsy: Pathological biopsy is the gold standard for the diagnosis of lymphoma. Doctors will obtain tissue samples suspected of lymphoma by surgery, endoscopy or puncture, and observe cell morphology and tissue structure under a microscope to determine the type and subtype of lymphoma. 5. Bone marrow examination: by drawing bone marrow fluid for examination, to understand whether there are lymphoma cells in the bone marrow infiltration, help to determine the extent of lymphoma involvement. It should be noted that for patients suspected of lymphoma, doctors will select appropriate examination methods according to specific conditions, and combine clinical manifestations, medical history, etc. for comprehensive analysis to ensure accurate diagnosis. In addition, for some special groups, such as the elderly, immunocompromised, etc., diagnosis may be more complicated and requires individual assessment and diagnosis by a doctor. If you or someone close to you has symptoms of suspected lymphoma, you should seek medical attention promptly and follow the doctor's recommendations for relevant tests for early diagnosis and treatment. At the same time, maintaining good living habits, balanced diet, moderate exercise, etc. also help to improve body immunity and prevent lymphoma.
