An inexpensive microfluidics chip could lead to earlier cancer detection and treatment. Read the Article from the MIT Technology review.
This is important, because the age of biology we are currently embarking on will truly be what people assume medicine is doing now. Diagnosis of cancer will identify perhaps not only the cell variant inducing the cancerous behaviour, but also potentially the cause either viral, carcinogenic, bacterial, radiological or endosystemic. I made that last word up, but basically, it means any attribute that is endogenous to an organism which may lead to the self-induction of cancer regardless of exogenous factors.
The future looks very bright. The ability to track cell variants at using small samples and hopefully address them, will lead to far better solutions and cures, not just therapies that will make chemotherapy and excision appear to be the truly crude techniques they are.
