Tiny microscope ‘could speed up breast cancer treatment and cut waiting lists’
A tiny microscope that can be manoeuvred through small spaces inside the body during surgery could speed up breast cancer treatment and help reduce NHS waiting lists, 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.
The device is able to produce images from inside the tissue with “unprecedented speed”, the team said.
The hope is that the endo-microscope, which is being developed by Dr Khushi Vyas and colleagues at Imperial College London, will help surgeons identify cancerous cells a hundredth of a millimetre in size at a much faster rate than traditional methods.
It will help reduce the need for follow-up operations to remove cancerous cells that previously evaded detection, the team said.
The instrument will also help with breast-conserving surgery, where the surgeon removes the cancer while leaving as much normal breast as possible.
At present, up to 20% of patients treated through breast-conserving surgery currently need such operations.
The researchers said using the device will help surgeons identify suspicious tissue around tumours very quickly and accurately – with the endo-microscope generating up to 120 frames per second.
The development of the endo-microscope is being supported by the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation.

EPSRC director for cross-council programmes, Dr Kedar Pandya, said: “By reducing the time it takes to identify cancerous cells and improve the accuracy of imaging, the endo-microscope developed by Dr Vyas and his team could benefit patients and the NHS by reducing waiting lists.”
Dr Khushi Vyas added: “Our aim is to proceed to clinical trials with a view to the system becoming available for deployment in around five years.”
The researchers have used their system for preliminary studies on human cancer tissue and are now testing its use by surgeons and pathologists on laboratory samples of cancerous tissue.
What are the signs of breast cancer in women?
The NHS website advises people to see a GP if they notice any of these symptoms:
A change in the size or shape of one or both breasts
Discharge from either nipple, which may be streaked with blood
A lump or swelling in either armpit
Dimpling on the skin of the breasts
A rash on or around the nipple
A change in the appearance of the nipple, such as becoming sunken into the breast
