|
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.

Your doctor may suggest that you have one or more of the following procedures to help make the diagnosis of lung cancer. After any kind of biopsy, a specialized doctor, called a pathologist, looks at the tissue samples under a microscope to check for cancer cells. It usually takes several days for the results of your biopsy to come back. A biopsy is the only sure way to tell if you have cancer and what kind of cancer it is.
