Unit
Review
Here is what we have learned from this unit:
- The biliary system is the organs and duct system
that create, transport, store, and release bile into
the duodenum for digestion.
- The biliary system includes the liver, gallbladder,
and bile ducts.
- In the United States, an estimated 20,000 new cases
of liver and biliary tract cancer are diagnosed annually.
- Because the early symptoms are vague, and there are
no screening tests to detect pancreatic cancer, early
diagnosis is difficult.
- Since the liver serves the vital function of filtering
all the circulating blood, cancer cells are likely
to travel, via the bloodstream, to the liver, making
it one of the most frequent sites of metastatic cancer.
- Gallbladder and bile duct cancers are rare, and together
make up only 2 to 3 percent of all cancers.
- Smoking and alcoholism are among risk factors for
developing pancreatic cancer.
- People with a history of chronic liver disease, such
as hepatitis B or C infections, are at high risk of
developing liver cancer.
- Known carcinogens for liver cancer include nitrosamines,
polyvinylchloride, thorotrast, aflatoxins.
- Jaundice, weight loss, fever, and nausea are some
of the common signs and symptoms for pancreatic and
biliary tract cancers.
