76 yr old male w/ asymptomatic microscopic hematuria. no kidney stones or uti. history of thymic cancer, benign kidney cyst. worked by toxic wtc site 18 yrs ago in the area (but not first responder). statistically would this point to bladder cancer?

Bladder pathology: Would be next to be ruled out through a cystoscopy. Prostate pathology is also common and can cause hematuria even through benign enlargement or BPH.

Get a workup:: Have you had any testing, like an ultrasound? You have had a test to detect the cyst but was this done when the microscopic hematuria was found? If it was done earlier, it should be repeated. Have you seen a urologist or nephrologist? Please do so.
