Leukemia is a malignant blood disease that is one of the common cancers that threaten human life. Before the 19th century, it was almost incurable. But there is a type of leukemia, but it is occasionally called the “lightest” disease. This type of indolent tumor, which is common in middle-aged and elderly patients, develops slowly. Patients often have no obvious symptoms and do not affect normal life. This relatively normal state may last for several years, ten years or even longer.

It is chronic lymphocytic leukemia (CLL). In Europe and the United States, CLL is the most common type of leukemia, accounting for about 25% to 30% of the total number of leukemias. Although the incidence of CLL in the Asian population is relatively low, as the public’s attention to health is getting higher and higher, the detection rate and diagnosis rate of CLL are gradually increasing. Today, let’s review the history of the struggle of human beings since it was discovered.
