How Does My Doctor Know I Hav... Health Article

Your doctor may find liver cancer during a routine visit, even if you don’t have symptoms. If you’re having symptoms of liver cancer, your doctor will ask you about these things.

• Your health history

• Your family’s history of cancer

• Your other risk factors

The doctor then performs a physical exam to look for signs of liver cancer. These signs may include yellowing of the skin and eyes, called jaundice, and an enlarged liver. The doctor may order tests to determine whether you have liver cancer. These tests may also help detecting the stage of the cancer. You may have one or more of these tests.

• Ultrasound. This test is very helpful in seeing whether a liver tumor is a cyst, a fluid-filled sac that is probably not cancer, or a solid mass that is more likely to be cancer. An ultrasound uses sound waves to look for abnormalities in the liver. The sound waves bounce off body parts and send back a series of signals. A computer then looks at these signals and creates an image of your body.

• MRI (magnetic resonance imaging). This test gives the best information about normal and abnormal details of the liver. An MRI uses magnets and radio waves to take pictures of the inside of the body. MRIs can show more detail than other X-rays.

  

• CT scan (computed tomography).  A CT scan uses an X-ray beam to take pictures of the body from many angles. A computer then combines these pictures, giving the doctor a very detailed cross-section picture of the body.

If one of these tests shows something in the liver that looks like it might be cancer, the doctor may take a small sample of liver tissue. This is called a biopsy. A doctor who specializes in looking at cells, called a pathologist, looks at the sample under a microscope to tell whether cancer is present. Some specific ways to get a biopsy are:

• FNA (fine needle aspiration)

• Core biopsy

• A biopsy taken during a laparoscopy
