Not all cancer cells are the same, nor do they pose equivalent risks. Oftentimes, humans can go their entire lives without ever knowing a growth is there, and they’re not harmed by its presence in the body.. In benign cases like this, detection, diagnosis and treatment – including chemotherapy, radiation and surgery – has the potential to do far more harm than good.

For the first time anywhere in the world, scientists there have calculated the risk of ‘overdiagnosing’ five different cancers. This is an incredibly difficult problem to quantify, since most of the time, doctors have no idea when a patient has been overdiagnosed; even […]
