Tiny endo-microscope could spot breast cancer cells forming

Device less than 1mm in diameter is designed to be inserted in body and produce images of tissue with unprecedented speed'

A tiny microscope that can be manoeuvred through small spaces inside the body during surgery could speed up breast cancer treatment, according to the scientists who created it.

Experts from Imperial College London have developed an endo-microscope that is less than 1mm in diameter - about the width of 25 human hairs - and is designed to be inserted into the body to provide views of tissue and organs.
