Summary

Jimmy Lin is developing technologies to catch cancer months to years before current methods. He shares a breakthrough technique that looks for small signals of cancer's presence via a simple blood test, detecting the recurrence of some forms of the disease 100 days earlier than traditional methods. It could be a ray of hope in a fight where early detection makes all the difference.

0:00.0	This TED Talk features geneticist Jimmy Lynn,
0:04.0	recorded live at TED 2017.
0:07.0	Cancer.
0:10.0	Many of us have lost family, friends, or loved ones to this horrible disease.
0:15.0	I know that there is some even in the audience who are cancer survivors
0:18.0	or ones who are fighting cancer at this moment.
0:20.0	Our heart goes out to you.
0:22.3	While this word often conjures up emotions of sadness and anger and fear,
0:27.6	I bring you good news from the front lines of cancer research.
0:31.2	The fact is, we are starting to win the war on cancer.
0:35.8	In fact, we lie at the intersection of three of the most exciting developments
0:39.8	within cancer research.
0:41.8	The first is cancer genomics.
0:44.2	The genome is a composition of all the genetic information
0:47.7	encoded by DNA in an organism.
0:50.6	And cancers, changes in the DNA,
0:52.4	called mutations are what drives these cancers to go out of control.
0:56.8	Around 10 years ago, I was part of the team at Johns Hopkins that first mapped the mutations
1:01.4	of cancers. We did this first for colorectal, breast, pancreatic, and brain cancers.
1:07.9	And since then, there have been over 90 projects in 70 countries all over the world
1:12.7	working to understand the genetic basis of these diseases. To date, tens of thousands of cancers are
1:18.6	understood down to exquisite molecular detail. The second revolution is precision medicine,
