Can taking Chinese herbal medicine for anti-tumor purposes cause blood in the urine?

The reasons for blood in urine while taking anti-tumor Chinese herbal medicine include the following:

1. Urinary system irritation: Some herbal ingredients may irritate the urinary system, potentially causing mucosal damage and resulting in hematuria (blood in urine).
2. Anti-tumor herbal components: Certain ingredients in anti-tumor Chinese herbs may affect blood coagulation function or cause adverse reactions in the body, such as excessive internal heat ("fire"), which may increase the likelihood of bleeding.
3. Urinary tract infection: Conditions such as urinary tract infections or urethritis are common causes of hematuria.
4. Other symptoms: If a patient notices red-colored urine while taking anti-tumor herbal medicine, they should seek professional medical evaluation promptly. Diagnostic tests such as urinalysis and ultrasound may be performed to determine the cause, and medication regimens should be adjusted when necessary to avoid delaying treatment.
5. Tumor metastasis: If the tumor has metastasized, particularly to the urinary system, this may also cause blood in the urine.
