Initial symptoms of leukemia may include anemia, fever, infection, bleeding, etc. The exact onset of the disease varies.
Leukemia is a type of malignant clonal disease of hematopoietic stem cells. Leukemia cells proliferate in large numbers, which inhibits the normal hematopoietic function of the bone marrow and also infiltrates other tissues and organs.
Leukemia causes suppression of the normal hematopoietic function of the bone marrow, resulting in anemia, infections such as oral, pharyngeal, and pulmonary infections, as well as fever and bleeding from the skin mucous membranes, gums, and nose.
In addition, leukemia cells infiltrate tissues and organs, and may present with symptoms such as enlarged lymph nodes, large liver and spleen, bone and joint pain, orbital granulocytic sarcoma, and gingival hyperplasia; they may also infiltrate the central nervous system to present with symptoms such as headache, dizziness, and vomiting, or infiltrate the testes to present with the symptom of painless enlargement of the testes.
Clinically, the situation of newly diagnosed leukemia patients varies, and depending on the diagnosis and condition, the above clinical manifestations may occur.
