Malignant lymphoma is referred to as lymphoma or lymphoma, but in fact lymphoma and lymphoma are talking about the same disease. Malignant lymphoma is a group of malignant tumors originating from lymph nodes and/or lymphatic tissues outside of lymph nodes. In western countries, the incidence of lymphoma is the eighth most common malignant tumor, while in China, lymphoma is relatively uncommon. The high incidence age is 40 to 50 years old, and the average age of death is less than 50 years old, with an incidence rate of 4-5/100,000 and an annual death rate of more than 20,000. Although its incidence is not as common as common cancers (such as lung cancer, stomach cancer, liver cancer, etc.), lymphoma often occurs in young adults, and the incidence of non-Hodgkin’s lymphoma is increasing at 3% per year, which is a serious health hazard to people. This is the reason why we often see some celebrities suffering from this disease in recent years. Lymphoma is a malignant blood tumor with a variety of symptoms, which is not easily detected early and treated well.
