Introduction
What is cancer?
Cancer is a disease caused by uncontrolled growth or division of cells in the body. Cancer can affect any part of the body. Some of the most common cancers are lung cancer, Skin cancers, Prostate cancers and Breast cancers in women.

The scan uses a special dye that has radioactive tracers. These tracers are either swallowed, inhaled, or injected into a vein in your arm depending on what part of the body is being examined. Your organs and tissues then absorb the tracer.
What a PET scan shows
The PET scan can show how well your organs and tissues are working. The tracer will collect in areas of higher chemical activity, which is helpful because a higher level of chemical activity is commonly associated with disease. These areas of disease will show up as bright spots on the PET scan. The PET scan can measure blood flow, oxygen use, how your body uses sugar, and much more.
How a PET scan machine works
A nurse injects a patient with a radioactive substance that attaches to a compound in the body such as sugar, called glucose. The patient then lies down on an exam table and is passed through the PET scan, which looks like a large donut. Rings in the machine detect the emission of energy from the radioactive substance in the body.

What is a X-ray scan
An X-ray, a type of high-energy electromagnetic radiation, is often used for medical imaging. X-ray technology may be used to examine many parts of the body. This image-guided technology is an important procedure for cancer diagnosis, staging and
