After being diagnosed with nasopharyngeal cancer, you have further tests to find out its size and whether it has spread. This tells you the stage of your cancer. The stage helps your doctor to decide the best treatment for you.
You might have one or more of these tests.
A CT scan uses x-rays to take detailed pictures of your body from different angles.
MRI stands for magnetic resonance imaging. It uses magnetism and radio waves to create cross section pictures of the body.
A PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal.
X-rays use small doses of radiation to take pictures of the inside of your body.
You might have a bone scan to see whether cancer has spread to your bones.
