1. Lymphoma is a malignant tumor originating from lymph nodes or lymphatic tissues. Its main clinical manifestation is painless and progressive lymphadenopathy. The disease can occur at any age, but the peak age of onset is between 31 and 40 years old, with the peak of non-Hodgkin's lymphoma slightly earlier. The male to female ratio is 2 to 3:

2. Malignant lymphoma, also known as "lymphoma", is a malignant tumor originating from lymph nodes or other lymphatic tissues. It is one of the ten most common malignant tumors in China. The disease is more common in middle-aged and young people, and male patients are more common than female patients.

3. The symptoms of malignant lymphoma vary greatly depending on the type of disease and the stage of the disease. Some patients with malignant lymphoma may have no systemic symptoms. Fever, weight loss of more than 10%, night sweats, etc. are more common in patients with symptoms, followed by loss of libido, fatigue, itching and other symptoms of malignant lymphoma. Systemic symptoms are related to the age of onset, tumor range, body immunity, etc.

Fever: Fever is the most common symptom of malignant lymphoma. The fever pattern is often irregular, and can be continuous high fever or intermittent low fever. A few have periodic fever, which is seen in about 1/6 of Hodgkin's disease patients. About 30% to 50% of patients with early fever have Hodgkin's disease, but non-Hodgkin's lymphoma generally only has fever when the lesions are more extensive. Sweating when the fever subsides can be a characteristic of this disease.

Skin itching: This is a more specific manifestation of Hodgkin's disease and is also a common symptom of malignant lymphoma. Focal itching occurs in the area of ​​lymphatic drainage of the lesion, and systemic itching mostly occurs in cases with lesions in the mediastinum or abdomen.

Alcohol pain: About 17% to 20% of patients with malignant lymphoma experience pain in the lesion 20 minutes after drinking. This symptom of malignant lymphoma may appear earlier than other symptoms and X-ray manifestations, and has a certain diagnostic significance. When the lesion is relieved, the alcohol pain disappears immediately, and reappears when it relapses. The mechanism of alcohol pain is unknown.
