Scientists edge closer to a blood test to detect cancers

Their experimental test, dubbed CancerSEEK, focuses on eight major cancers: lung, breast, colon, pancreas, liver, stomach, ovary and esophagus.

“We selected those eight cancers based on how frequent they are, also [because] a lot of them do not have any screening modality right now,” Papadopoulos says.

The researchers looked at 1,005 people who had been diagnosed with these cancers. The blood test found signs of cancer in about 70 percent of them.
