Breast cancer metastatic to the urinary bladder.

Breast cancer is common and has the potential to spread to multiple organs. This article describes metastasis to the urinary bladder. In most instances, breast cancer metastatic to the bladder is associated with other pelvic organ metastasis. In patients with known metastatic breast cancer, bladder screening is not warranted. However, if lower urinary tract symptoms persist, an evaluation of the bladder should be considered to rule out metastatic involvement.
