Overview

It is hard to detect early forms of gallbladder cancer. Like other cancer diseases, doctors need to administer many tests to diagnose cancer and determine whether it has metastasized. For most types of cancer, a biopsy is the best way to make a definitive diagnosis of cancer. If a biopsy is not possible, other image tests are recommended such as computed tomography (CT) scan, Magnetic resonance imaging (MRI) or Positron emission tomography (PET) scan.

CT

• Computed tomography (CT) scan and biopsy: CT scans are often used to diagnose gallbladder cancer. It can confirm the location of the cancer and show the organs near the gallbladder, as well as lymph nodes and distant organs where the cancer might have spread. These are helpful in staging the cancer and in determining whether surgery is a good treatment option. CT scans can also be used to guide a biopsy procedure and a biopsy sample is then removed and looked at under a microscope.
