Bladder cancer is a relatively common malignant tumor in the urinary system and tends to occur more frequently in males, with the incidence rate being three to four times higher than that in females. Painless hematuria is likely to be caused by bladder cancer. Therefore, it is crucial to be cautious when hematuria occurs and to seek medical examination at a hospital as soon as possible, such as urinalysis and bladder ultrasound exams, which are non-invasive and relatively inexpensive. Early-stage bladder cancer can potentially be cured, especially if it is superficial. However, patients with poorly differentiated and highly malignant forms may undergo infusion chemotherapy and immunotherapy. Studies have shown that patients with minor bladder cancer, after undergoing systematic treatment, have a relatively high five-year survival rate.
