Scientists have developed a noninvasive blood test that can detect signs of eight types of cancer long before any symptoms of the disease arise.
The test, which can also help doctors determine where in a person's body the cancer is located, is called CancerSEEK. Its genesis is described in a paper published Thursday in the journal Science.
The authors said the new work represents the first noninvasive blood test that can screen for a range of cancers all at once: cancer of the ovary, liver, stomach, pancreas, esophagus, colon, lung and breast.
Together, these eight forms of cancer are responsible for more than 60% of cancer deaths in the United States, the authors said.
