Is leukemia a malignant tumor?
Generally speaking, leukemia is classified as a malignant tumor and is a malignant disease of the hematopoietic system. The detailed analysis is as follows:

Leukemia is defined as a malignant tumor of the hematopoietic system, characterized primarily by malignant transformation of hematopoietic stem cells. These cells lose their normal ability to differentiate and mature, resulting in uncontrolled proliferation and infiltration of various tissues and organs throughout the body. These malignant cells suppress normal bone marrow function, impairing the production of red blood cells, white blood cells, and platelets, thereby causing symptoms such as anemia, infections, and bleeding. Moreover, the abnormal cells can spread via the bloodstream to sites such as lymph nodes, liver, and spleen, causing systemic damage to the body.
To slow disease progression and improve quality of life, daily care requires special attention. Diet should prioritize high-protein, high-vitamin foods, prepared in a light and easily digestible manner to help maintain energy levels. Keep indoor air circulating, regularly clean and disinfect living spaces, and avoid crowded places to reduce the risk of infection. Engage in mild physical activities such as walking according to individual physical condition, avoiding excessive exertion. Additionally, monitor for skin bruising or petechiae, check for gum bleeding, and track body temperature; seek medical attention promptly if any abnormalities are detected.
