Bladder space occupying hematuria must be cancer?

Hematuria is not necessarily cancer. Patients with bladder cancer are prone to hematuria because of cancer infiltration of surrounding tissues, resulting in damage to urinary tract mucosa. However, clinically, there are space-occupying lesions in the bladder, hematuria may also be related to benign lesions. For patients with chronic cystitis, local hyperplasia may be formed under the stimulation of chronic inflammation, causing inflammatory pseudotumor.

Patients with benign lesions such as bladder leiomyoma, bladder cystic lesions and bladder polyps are also prone to vascular compression or injury due to increased lesion volume, resulting in hematuria symptoms.
