A low-grade fever that does not go away is not necessarily a precursor to leukemia. There are many causes of a low fever that does not go away, such as a decrease in the immunity of the body, chronic inflammation, tuberculosis, malignant tumors and other diseases.
A low fever that does not go away may have leukemia and may also have pernicious anemia or aplastic anemia, but it is not necessarily a precursor to leukemia. A low fever that does not subside may be due to bacterial infections, viral infections, and mycoplasma and chlamydia infections, or it may be caused by abnormalities in the temperature center, abnormalities in skin heat dissipation, absorption of sterile necrotic material, and some autoimmune diseases, such as tuberculosis, rheumatism, connective tissue disease, and even malignancy and AIDS. In addition, hypothermia can also be caused by the presence of cardiac decompensation in the elderly.
Therefore, if hypothermia does not go away, you need to go to the hospital for a comprehensive examination. You can do blood routine, biochemistry, lung CT and other related examinations, and when leukemia is suspected, further bone marrow aspiration is needed to confirm the diagnosis.
