Chile also has among the highest rates of gallbladder cancer and death in the world. Researchers in a high-risk region of Chile want to find out more about this type of cancer. They especially want to know how inflammation affects the way it develops.

Participants will have a physical exam.

Participants will have their mouths looked at for tooth loss, dentures, and gum redness.

Participants will give a blood sample or saliva sample.

Participants will be asked for access to their medical history. They may be asked to allow researchers to keep any samples taken during gallbladder surgery.
