Question: Cancer Test
|concernedpatient30 - Wed Dec 27, 2006 5:40 pm||
I heard the tail end of a topic on the news about a new procedure or scan for assumed healthy people to preventatively look for any cancer or disease in the whole body.
Does anyone know what its called or if such a thing exists?
(maybe I misheard it?) If so, is there a suggested age for obtaining such a test?

Did you mean PET Scan?
Positron emission tomography (PET) is a test that help physicians to detect changes in biochemical processes that suggest disease (including cancer) before gross changes are visible and detected by other imaging tests,like CT or MRI.
The guideline for PET scan indications are evolving from different research studies.
It is very expensive , not available in all centers and doctors usually perform it when a lesion is suspected and can not be diagnosed with conventional techniques. CT scan is usually done with PET.
Hope this information is useful.
