I was reading through the popular science site and I came up on this.
QuoteBy 2011, doctors expect a painless spit cup to replace certain dreaded blood tests. Scientists working on the $12-million Human Salivary Proteome Project have recently identified 1,166 proteins in saliva, including five indicators of oral cancer. They have also found specific markers in the spit of patients with breast cancer and the autoimmune disease Sjogren's syndrome and are now working to identify the protein linked to ovarian cancer. Detecting the proteins during a routine spit test could help doctors diagnose cancers early enough to cure them, not to mention spare patients painful needle pricks.
That would be nice. It would save a lot of money and be relatively easy and take a lot less time for the patient.
That's really neat. Good find.
