X-rays have the property that can traverse relatively thick objects without being much absorbed or scattered, thus, x-Rays are used in medicine to capture images of most parts of the human body. Through the use of invisible electromagnetic energy, which slips through the layers of mass and bones in the human body, images are captured on a thin film, thus producing an x-ray. These images assist in achieving a clear idea of what is really happening under the several layers of tissue and muscle in the human body. The penetration depth varies with several orders of magnitude over the X-ray spectrum.

To detect for tumors in cross-sections of the body, computed tomography (CT) scan is used. A CT scan is an imaging method that uses x-rays to create pictures of cross-sections of the body. It is a medical imaging modality where tomographic images or slices of specific areas of the body are obtained from a large series of two-dimensional X-ray images taken in different directions.
X-rays are broadly categorized into:
Generally, there are no side effects of routine diagnostic X-rays. Though, one may experience bleeding, pain, swelling or redness, if he or she has received an injection of contrast medium just before the X-rays. If this happens, it is best to consult with the doctor.
