About This Study


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 Cancer Institute 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.


Participants must be 18 years of age or older, recently diagnosed with non-muscle invasive (superficial) bladder cancer, and members of Kaiser Permanente Northern California or Kaiser Permanente Southern California.


Participation in the study involves the following:

  • Sign an informed consent form
  • Complete an initial telephone interview
  • Give a blood sample and urine sample at time of enrollment
  • Complete follow-up telephone interviews and provide urine and saliva samples one year and two years after the first interview
  • Give permission to access your Kaiser Permanente medical record
