Cancer: Diagnostics and Staging

X-radiation (composed of X-rays) is a form of electromagnetic radiation Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. An ultrasound scan, sometimes called a sonogram, is a procedure that uses high-frequency sound waves to create an image of part of the inside of the body. A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving sampling of cells or tissues for examination. A complete blood count (CBC) gives important information about the kinds and numbers of cells in the blood, especially red blood cells camera.gif, white blood cells camera.gif, and platelets. Cancer staging is the process of determining the extent to which a cancer has developed by spreading. The TNM Classification of Malignant Tumours (TNM) is a cancer staging notation system that gives codes to describe the stage of a person's cancer, when this originates with a solid tumor. Pathologic staging, where a pathologist examines sections of tissue, can be particularly problematic for two specific reasons: visual discretion and random sampling of tissue.
