(April 7, 2014) – Could a simple blood test diagnose cancer?

Researchers at the Stanford University School of Medicine believe it’s possible. They’ve developed a new test that can diagnose if someone has cancer and even provide details about the disease such as the type and how advanced it’s become.

The test checks the levels of tumor DNA in a person’s bloodstream, giving doctors the idea of a tumor’s size and how it’s responding to treatment. Researchers believe the treatment could detect common cancers such as breast, prostate and lung cancer.

The new test could also let doctors know which treatments work for certain patients and which ones don’t, allowing them to customize treatments.
