Scientists at Johns Hopkins University in Baltimore say they are close to coming up with a simple blood test that would detect a number of types of cancer at an early stage. Researcher Peter Gibbs says if proven, the blood test will be a game changer.
In a study published in the journal “Science,” researchers looked to see how well their experimental blood test detected cancer in people already known to have the disease.
The blood tests found about 70% of eight common types of cancer in just over1,000 patients. But rates seem to vary depending on the type of cancer.
In many cases, the test narrowed the possible origin of the cancer to one or two places, such as colon or lung, important for limiting how much follow-up testing a patient might need.However, the test itself needs more testing before it’s ready for wider use.
