​​​​​​​​​​​​About This Study

​​Purpos​e​

​​​Bladder cancer is among the ten most common cancers in the United States. Although it is often diagnosed and treated early, the disease can return in certain people.

By gathering information about diet and lifestyle, researchers at Kaiser Permanente Northern California and Southern California, in collaboration with Roswell Park Comprehensive Cancer Center in Buffalo, NY, are trying to find out whether your lifestyle choices including physical activity and diet have any effect on disease recurrence and your health after bladder cancer diagnosis. Furthermore, by collecting tumor tissues and other biospecimens from you, researchers are aimed to find out whether any biomarkers or tumor features can help predict disease recurrence and offer additional insights on improving cancer care.
