In the decades since, clinicians have performed countless biopsies on suspected cancer patients, all to catch a glimpse of cells on the brink of growing out of control. This year alone, more than a million breast biopsies will be performed in the U.S.

These potentially life-saving procedures come at a price, both in finances and flesh, as they require clinicians to carve out pieces of tissue or suck up cells with a large needle.

“That’s the Holy Grail. It’s what everybody is hoping for,” said Fergus Couch, Ph.D., a cancer geneticist. Dr. Couch and dozens of researchers at Mayo Clinic, along with partners in industry, are part of a national push to develop such a test.
