Finding cancer at its earliest stage can give the best chance of being able to cure it. Different tests are used to find cancers and to help find out if the cancer has spread. A positron-emission tomography (PET) scan is one type of test that can help find and stage cancers as well as monitor how well treatment is working.

A biopsy is the removal of a small piece of tissue for laboratory examination.

|
|
A biopsy is a small sample of tissue or fluid taken from the body. This sample can then be studied in a laboratory. Image-guided biopsy allows a sample to be taken from an abnormal mass without the need for surgery. This procedure is done by a specially trained doctor called an interventional radiologist.

Detailed information on biopsy and the biopsy report For many health problems, a diagnosis is made by removing a sample of tissue for study in the pathology laboratory. The biopsy report describes the findings of a specimen.
|
|
Most biopsies involve taking a small piece of skin or muscle under a local anesthetic. When the cells to be analyzed are accessible by needle, the biopsy specimen may be removed with a hollow aspiration needle, which is used to suck out the sample...

|
|
Detailed information on chest x-rays, including reasons for the procedure X-rays are made by using low levels of external radiation to produce images of the body, the organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially treated plates (similar to camera film) and a "negative" type picture is made. The more solid a structure is, the whiter it appears on the film. For this reason, bones appear very white on an x-ray film, but less dense tissue such as muscle, blood, skin, and fat appears darker.

Detailed information on spinal tap, also called lumbar puncture A spinal tap, also called lumbar puncture, is done to measure the amount of pressure in the spinal canal and/or to remove a small amount of cerebral spinal fluid (CSF) for testing. Cerebral spinal fluid is the fluid that bathes your child's brain and spinal cord. In some cases, a spinal tap may also be done so medication can be injected into the spinal fluid, or to remove excess CSF in babies with hydrocephalus (a condition in which there is an overproduction or lack of absorption of the cerebral spinal fluid that is found inside the ventricles, fluid-filled areas, inside of the brain). A special needle will be used for the spinal tap.

A lumbar puncture is also called a spinal tap. A lumbar puncture may be used to look for problems in your brain, spinal cord, and related structures.
