Early detection of cancer cells via blood test

A research team from the Cancer Research UK build a genetic finger print of cancer cells taken from surgically removed lung tumors. They then used the genetic finger print to test blood samples for the re-emergence of cancerous. This is an exciting development because it can that can detect cancer cells that are invisible to CT scans or X-rays and potentially leading to early treatment.
