Imaging Tests: In this test, the picture of the area inside the body are created which help to see the tumor present or not. It involves tests like:
Ct Scan: This scan is used to create 3-dimension images of your organs from different angles by X- ray machines which are linked to the computer. Usually, before the scanning, you may have to take a dye or other contrast material which helps to make the picture easier to identify certain areas of body. In the donut-shaped scanner machine the picture taken by moving around the body.
MRI: This scan is also used to take the picture of the body organs by taking pictures in slices and create detailed image. Radio waves and powerful magnet are used to take the slices. This scan shows the exact difference between unhealthy and healthy tissues. As in CT scan, before MRI scans also you have to take a dye for further scan. It is a round chamber machine in which the body is pushed and it makes rhythmic beats and loud thumping noise.
Nuclear Scan: It is also called a radionuclide scan because radioactive material is used to take the picture of body organs. As a CT and MRI scan, the person needs to receive a small amount of radioactive material in the injection form known as a tracer. It collects in the bones by flowing through blood. In this scanner measure the radioactivity and create pictures of organs or bones on film or on the screen of the computer. It includes 2 scans named as: Pet and bone scan.
Bone Scan: It is used to checking for damage to bones or abnormal areas. Before the scan person has to take the small radioactive material in his/her
vein, it travels through the blood and collects in an abnormal area in the bones. A special scanner pictured the material where it collects, and these areas are called hot spots.
Pet Scan: In this scan, the radioactive glucose material is used for the 3-D picture of body organs because cancer cells consume more glucose than healthy cells.
Ultrasound: In ultrasound, high energy sound waves are used for the echo of tissues because these waves, people cannot hear. The computer uses these echoes to create a picture of body organs where a device called transducer slowly moves on the skin and the picture is called a sonogram.

    rays: In X-ray scan, x-rays are used in low doses of radiation to create a picture of body organs and you have to stay still withholding the breath for 1-2 seconds when the beam is directing on the body part.
    

Biopsy: Biopsy is the test in which the doctor removes a sample of tissue from the patient's body for diagnosing cancer. Then a pathologist does further test and looks tissue in the microscope and described all details in the pathology report. Sedative and anesthesia are given to patients before biopsy for relaxation. The biopsy sample is obtained in various ways:

1. 
   With Needle: Needle is used to withdraw fluid or tissue from the body. This method is used for spinal taps, bone marrow aspirations, prostate, and liver and breast biopsies.
