Lymphoma

Lymphoma is a malignant tumor originating from lymph nodes and lymphatic tissues, and can occur in any part of the body. Lymphoma is usually characterized by painless, progressive lymphadenopathy. It can also invade extranodal organs such as the nasopharynx, gastrointestinal tract, bones, and skin, causing damage to the corresponding organs, often accompanied by systemic symptoms such as fever, weight loss, and night sweats. According to pathological characteristics, lymphoma is mainly divided into Hodgkin lymphoma and non-Hodgkin lymphoma. Hodgkin lymphoma (HL): The initial symptom is often lymphadenopathy, and the progression is relatively slow. This type of lymphoma responds well to treatment, and most patients can be cured after standardized treatment. Non-Hodgkin lymphoma (NHL): Often involves extranodal lesions and progresses rapidly, except for indolent lymphomas. The most common non-Hodgkin lymphoma in China is diffuse large B-cell lymphoma.
