What are the benefits and risks of screening?
Gallbladder cancer screening is generally not recommended, mainly because physical examinations can hardly detect the presence of gallbladder cancer in early stages, and routine blood tests are not available for people without symptoms.
How to do gallbladder cancer screening?
Gallbladder cancer is generally hard to find early because the organ is deep seated within the body. Therefore, early tumors can’t be seen or felt during routine physical exams. Besides, there are no blood tests or other tests that can reliably detect early stage gallbladder cancers in people who do not experience any symptoms. Because of this, most gallbladder cancers are found only after the cancer has grown enough to cause any signs or symptoms which include unexplained abdominal pain and swelling. Some patients also experience jaundice, nausea, vomiting, weight loss or fever.
That said, gallbladder cancers are usually found unexpectedly when a person’s gallbladder is removed because of gallstones.
