Can prolonged low-grade fever lead to leukemia?

Long-Term Low-Grade Fever and Leukemia

Long-term low-grade fever generally does not lead to leukemia. It can be caused by infectious diseases, immune system disorders, endocrine disorders, or malignant tumors. However, the triggers of leukemia are diverse, encompassing not only infectious diseases but also genetic factors, physical factors, chemical factors, and more.

1. Infectious Diseases

Long-term recurrent infections, such as bacterial, viral, or fungal infections, can result in persistent low-grade fever.

2. Immune System Disorders

Diseases like rheumatoid arthritis and systemic lupus erythematosus may also cause long-term low-grade fever. Rheumatoid arthritis manifests as joint swelling and pain, while systemic lupus erythematosus presents with fever, joint pain, kidney damage, among other symptoms. Untreated rheumatoid arthritis can lead to prolonged low-grade fever.

3. Endocrine Disorders

Hyperthyroidism, due to excessive thyroid hormone secretion causing increased metabolism, can also result in long-term low-grade fever. Patients with hyperthyroidism require anti-thyroid treatment, including medication like propylthiouracil, or radioactive iodine therapy, and surgical intervention.

4. Malignant Tumors

Malignant tumors such as lung cancer, gastric cancer, and lymphoma can stimulate the immune system, leading to long-term low-grade fever. Diagnostic tests like chest CT, gastroscopy, and colonoscopy are necessary to identify the underlying cause. If experiencing long-term low-grade fever, it is advisable to promptly consult a doctor for relevant tests like blood tests, urine tests, and chest X-rays, followed by targeted treatment under professional guidance to avoid complications.

In daily life, ensure adequate rest, avoid staying up late or overexertion, and engage in moderate exercise to strengthen your physique and aid recovery.
