There is an intriguing little-known blood test for cancer
in both women & men called the amas test from oncolab in boston.
Like all tests it's not perfect, but research shows it detects cancer 93% of the time. However, 5% of those without cancer will have a false positive test. Thus, a positive test requires further testing to see where a possible cancer is. See http://www.Oncolabinc.Com/index.Php.
