Soon we'll be able to spot diseases like cancer before we even feel sick

Within five years nanotechnology will examine bodily fluids for tiny bioparticles that reveal signs of cancer - helping to stop disease before it progresses

The sooner a disease is diagnosed, the more likely it is to be well managed or cured. The challenge to finding a disease early is that most of us don't seek treatment until we have symptoms, which means the disease has already progressed.

But breakthroughs in nanobiotechnology techniques mean that in five years we will be able to examine and filter bodily fluids for tiny bioparticles that reveal signs of disease like cancer before we have any symptoms, letting us know immediately if we should consult a doctor.
