Gallbladder Cancer (cont.)
Being female can increase the risk of developing gallbladder cancer.
Anything that increases your chance of getting a disease is called a risk factor. Risk factors for gallbladder cancer include the following:
- Being female.
- Being Native American.
Possible signs of gallbladder cancer include jaundice, pain, and fever.
These and other symptoms may be caused by gallbladder cancer. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:
Gallbladder cancer is difficult to detect (find) and diagnose early.
Gallbladder cancer is difficult to detect and diagnose for the following reasons:
- There aren't any noticeable signs or symptoms in the early stages of gallbladder cancer.
- The symptoms of gallbladder cancer, when present, are like the symptoms of many other illnesses.
- The gallbladder is hidden behind the liver.
Gallbladder cancer is sometimes found when the gallbladder is removed for other reasons. Patients with gallstones rarely develop gallbladder cancer.
Tests that examine the gallbladder and nearby organs are used to detect (find), diagnose, and stage gallbladder cancer.
Procedures that create pictures of the gallbladder and the area around it help diagnose gallbladder cancer and show how far the cancer has spread. The process used to find out if cancer cells have spread within and around the gallbladder is called staging.
In order to plan treatment, it is important to know if the gallbladder cancer can be removed by surgery. Tests and procedures to detect, diagnose, and stage gallbladder cancer are usually done at the same time. The following tests and procedures may be used:
- Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
- Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. An abdominal ultrasound is done to diagnose gallbladder cancer.
- Liver function tests: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of liver disease that may be caused by gallbladder cancer.
- Carcinoembryonic antigen (CEA) assay: A test that measures the level of CEA in the blood. CEA is released into the bloodstream from both cancer cells and normal cells. When found in higher than normal amounts, it can be a sign of gallbladder cancer or other conditions.
- CA 19-9 assay: A test that measures the level of CA 19-9 in the blood. CA 19-9 is released into the bloodstream from both cancer cells and normal cells. When found in higher than normal amounts, it can be a sign of gallbladder cancer or other conditions.
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an X-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease in the organ or tissue that produces it.
- Chest X-ray: An X-ray of the organs and bones inside the chest. An X-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
- MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). A dye may be injected into the gallbladder area so the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine will show up better in the image. This procedure is called MRCP (magnetic resonance cholangiopancreatography). To create detailed pictures of blood vessels near the gallbladder, the dye is injected into a vein. This procedure is called MRA (magnetic resonance angiography).
- ERCP (endoscopic retrograde cholangiopancreatography): A procedure used to X-ray the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Sometimes gallbladder cancer causes these ducts to narrow and block or slow the flow of bile, causing jaundice. An endoscope (a thin, lighted tube) is passed through the mouth, esophagus, and stomach into the first part of the small intestine. A catheter (a smaller tube) is then inserted through the endoscope into the bile ducts. A dye is injected through the catheter into the ducts and an X-ray is taken. If the ducts are blocked by a tumor, a fine tube may be inserted into the duct to unblock it. This tube (or stent) may be left in place to keep the duct open. Tissue samples may also be taken.
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The biopsy may be done after surgery to remove the tumor. If the tumor clearly cannot be removed by surgery, the biopsy may be done using a fine needle to remove cells from the tumor.
- Laparoscopy: A surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. Other instruments may be inserted through the same or other incisions to perform procedures such as removing organs or taking tissue samples for biopsy. The laparoscopy helps to determine if the cancer is within the gallbladder only or has spread to nearby tissues and if it can be removed by surgery.
- PTC (percutaneous transhepatic cholangiography): A procedure used to X-ray the liver and bile ducts. A thin needle is inserted through the skin below the ribs and into the liver. Dye is injected into the liver or bile ducts and an X-ray is taken. If a blockage is found, a thin, flexible tube called a stent is sometimes left in the liver to drain bile into the small intestine or a collection bag outside the body.
