In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Imaging cancer in children using MRI: an interview with Dr. Heike E. Daldrup-Link, Stanford University School of Medicine

There have been a number of scientific publications recently that suggest that the radiation exposure from imaging tests can induce secondary cancers later in life.

Engineers develop paper test that could improve diagnosis rates for cancer

Cancer rates in developing nations have climbed sharply in recent years, and now account for 70 percent of cancer mortality worldwide. Early detection has been proven to improve outcomes, but screening approaches such as mammograms and colonoscopy, used in the developed world, are too costly to be implemented in settings with little medical infrastructure.
