Cancer Detection
The process of detecting cancer takes many steps. It may be discovered when the patient goes to a doctor because of other reason, by chance or from screening. However, the final test to determine if a patient has cancer is mainly based on a pathologist’s verification.
The most common methods for detecting cancer is through the process of radiological imaging. This process is also use for monitoring the spread of cancer and progress of treatment. Different imaging techniques are used to test for the most optimal treatment, as every patient are unique. The lists below are the imaging methods used to detect cancer in no particular order.
Magnetic Resonance Imaging (MRI) is a process of using powerful magnetic fields to detect cancer or sarcoma around the head and neck region.
Computed Tomography (CT) is the most common method of detecting cancer. CT scans are made using X-rays.
Ultra sound examination is the method of choice when examining lower parts of the body such as liver, kidney and the cervix.
Endoscopic examinations are often use for examining the gastrointestinal tract, prostrate, bladder or head and neck areas.
Positron Emission Tomography (PET) In this method, the patients are given a radioactive tracker that is detectable by scintigraphy. It is based on the quicker metabolic rate of cancer cells in comparison to normal cells. This method can also be used in combination with CT.
Mammography uses X-ray image in breast cancer screening and to find breast tumors.
