2. So Tomlins and his colleagues are evaluating a new test that would identify a genetic anomaly that is linked to cancer.

例句：The plots of these stories almost always turn on love triangles.

4. Tomlins says this particular gene pair is unique to prostate cancer - it doesn't show up in normal prostate tissue, and it isn't found in other cancers.

6. I think the idea that you'll have a test that is 100 percent specific for cancer, it's 100 percent sensitive, and it will only identify the type of cancer that's aggressive and needs to be treated - I think that we are very far away from that, and I don't know if we'll ever be able to do that.
