Tests and diagnosis discussion for Liver cancer: If a patient has symptoms that suggest liver cancer, the doctor performs one or more of the following procedures:
-
Physical exam -- The doctor feels the abdomen to check the liver, spleen, and nearby organs for any lumps or changes in their shape or size. The doctor also checks for ascites, an abnormal buildup of fluid in the abdomen. The doctor may examine the skin and eyes for signs of jaundice.
-
Blood tests -- Many blood tests may be used to check for liver problems. One blood test detects alpha-fetoprotein (AFP). High AFP levels could be a sign of liver cancer. Other blood tests can show how well the liver is working.
-
CT scan -- An x-ray machine linked to a computer takes a series of detailed pictures of the liver and other organs and blood vessels in the abdomen. The patient may receive an injection of a special dye so the liver shows up clearly in the pictures. From the CT scan, the doctor may see tumors in the liver or elsewhere in the abdomen.
-
Ultrasound test -- The ultrasound device uses sound waves that cannot be heard by humans. The sound waves produce a pattern of echoes as they bounce off internal organs. The echoes create a picture (sonogram) of the liver and other organs in the abdomen. Tumors may produce echoes that are different from the echoes made by healthy tissues.
-
MRI -- A powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.
-
Angiogram -- For an angiogram, the patient may be in the hospital and may have anesthesia. The doctor injects dye into an artery so that the blood vessels in the liver show up on an x-ray. The angiogram can reveal a tumor in the liver.
-
Biopsy -- In some cases, the doctor may remove a sample of tissue. A pathologist uses a microscope to look for cancer cells in the tissue. The doctor may obtain tissue in several ways. One way is by inserting a thin needle into the liver to remove a small amount of tissue. This is called fine-needle aspiration. The doctor may use CT or ultrasound to guide the needle. Sometimes the doctor obtains a sample of tissue with a thick needle (core biopsy) or by inserting a thin, lighted tube (laparoscope) into a small incision in the abdomen. Another way is to remove tissue during an operation.
