Would like to get current data from reputable source on select group
of approved lab tests used in cancer diagnosis and monitoring.  For as
many of the tests listed below as possible, I would like to know:

1) Number of tests ordered annually in US
2) Number of tests ordered annually worldwide
3) Annual market size in US (i.e., $MM)
4) A percent estimate of how the market for each test has (or will)
grow over a given period of time

2) CA 125
3) CA 15-3
4) CA 19-9
5) CA 72-4
6) Prostate-specific antigen (PSA)
