"Can Chronic Fever Always Be a Sign of Leukemia?"

Prolonged fever may indicate leukemia, but it can also be associated with other diseases such as pneumonia, connective tissue diseases, typhoid fever, and malignant tumors. If fever persists, it is recommended to visit the internal medicine department of a hospital for a blood routine test, blood biochemistry, and other relevant examinations to determine the cause and undergo treatment under medical guidance.

1. Leukemia

Leukemia is a malignant clonal disease of hematopoietic stem cells. Clonal leukemia cells proliferate and accumulate in the bone marrow and other hematopoietic tissues, while secreting negative regulatory factors for hematopoiesis, inhibiting normal hematopoiesis, significantly increasing the number of white blood cells, and stimulating the thermoregulatory center to cause fever. Due to the different causes and fever mechanisms of leukemia, there is no specific targeted drug treatment available. Chemotherapy, radiotherapy, immunotherapy, and other related treatments are usually required under medical advice.

2. Pneumonia

Pneumonia is a lung infection caused by bacteria, viruses, mycoplasmas, etc. If treatment is delayed, it may develop into severe pneumonia, which can cause prolonged fever due to inflammatory stimulation. Antibiotics or antiviral drugs should be prescribed for the specific infectious pathogen, such as Amoxicillin Capsules and Cefixime Tablets.

3. Connective Tissue Diseases

Connective tissue diseases refer to diseases that affect connective tissues, including systemic lupus erythematosus, rheumatoid arthritis, etc. Clinical symptoms often include joint pain and swelling, prolonged fever, morning stiffness, muscle pain, etc. Non-steroidal anti-inflammatory drugs can be prescribed for treatment, such as Aspirin Enteric-coated Tablets and Paracetamol Tablets.

4. Typhoid Fever

Typhoid fever is an acute intestinal infectious disease caused by Salmonella typhi. Clinical symptoms include fever, abdominal pain, prolonged fever, rapid heartbeat, etc. Paracetamol Tablets and Aspirin Enteric-coated Tablets should be prescribed for treatment, and isolation measures should be implemented.

5. Malignant Tumors

Diseases such as lung cancer and leukemia may cause prolonged fever due to the stimulation of tumor necrosis factors on the thermoregulatory center. Treatment for the tumor, such as surgical resection, radiotherapy, and chemotherapy, should be performed under medical guidance.
