Event Information I have been diagnosed with an uncommon cancer (bile duct/gallbladder cancer). What do I ask my doctor? Sometimes, the hardest part about that first doctor visit is knowing what to ask or expect. Dr. Aaron Lewis will take patients through the steps of getting a diagnosis of a rare cancer such as bile duct/gallbladder cancers, decisions that will need to be made and up to date treatment options. He will discuss what questions to ask your doctors when presented with the unknowns associated with an uncommon cancer to stay informed. Join Dr. Aaron Lewis, oncologic surgeon at City of Hope, for this cancer awareness month presentation on gallbladder and bile duct tumors.
