New blood test can spot lung cancer relapses up to a year before scans

Scientists have developed a blood test which spots the relapse of lung cancer in patients, up to a year before the disease can be detected by CT scans and X-rays.

The groundbreaking TRACERx study, funded by Cancer Research UK, identified the cause of relapse of the disease and how it spreads, in a discovery that could lead to earlier treatment for patients.
