Lymphoma will slowly erode various organs of the human body and cause various symptoms, such as joint pain, waist and abdominal pain, itching, nasal congestion, etc. So how harmful is lymphoma to the body?

1. Extranodal lesions. Lymphoma can invade all tissues and organs of the body. For example, infiltration of the liver and spleen causes hepatomegaly; infiltration of the gastrointestinal tract causes abdominal pain, bloating, intestinal obstruction and bleeding; infiltration of the lungs and pleura causes cough and pleural effusion; infiltration of the bones causes bone pain and pathological fractures; infiltration of the skin causes itching and subcutaneous nodules; infiltration of the tonsils and mouth, nose and pharynx causes dysphagia, nasal congestion and nasal knots; infiltration of the nervous system causes spinal cord compression and cranial neuropathy, etc.
2. Local manifestations. (1) Lymph node enlargement: including superficial and deep lymph nodes. The characteristics of the enlarged lymph nodes are that they are progressive, painless, hard, and can be moved. In the early stage, they are not adhered to each other, but in the late stage, they can fuse. Anti-inflammatory and anti-tuberculosis treatments are ineffective. Superficial lymph nodes are more common in the neck, followed by the axilla and the ventral groin. Deep lymph nodes are more common in the mediastinum and beside the abdominal aorta. (2) Local compression symptoms caused by lymph node enlargement: mainly refers to deep lymph nodes, such as enlarged mediastinal lymph nodes, which can compress the esophagus and cause dysphagia; compress the superior vena cava to cause superior vena cava syndrome; compress the trachea to cause cough, chest tightness, dyspnea and cyanosis.
