A hand-held device can determine cancerous tissue in 10 seconds, in a move with researchers on the college of Texas.
They are saying it is capable to shape surgical treatment to cast off a tumour earlier, safer and more extra unique.
And that they hope it might retain away from the "heartbreak" of leaving any of the utmost cancers at the back of.
Tests, posted in technology translational medicine, recommend the technology is right ninety-six per cent of the time.
The masspec pen takes advantage of the specific metabolism of most cancers cells. Commercial.
Their energetic pressure to grow and explain means their internal chemistry might be very unique to that of strong tissue.
How it works
The pen is touched directly to a supposed most cancers and releases a tiny droplet of water.

The pen is plugged right into a mass spectrometer - a piece of kit that may measure the mass of hundreds of chemicals each 2nd.
It produces a chemical fingerprint that tells docs whether or not they're looking at healthy tissue or cancer.
The task for surgeons is finding the border between the most cancers and normal tissue.
In some tumours it's miles apparent, however, in others, the boundary between healthful and diseased tissue may be blurred.
The pen must help medical doctors make certain none of the most cancers is left in the back of.
Eliminate too little tissue, and any ultimate cancerous cells will develop into some other tumour. However take an excessive amount of, and you could reason harm, specifically in organs including the brain.
Livia Eberlin, an assistant professor of chemistry on the University of Texas, Austin, instructed the BBC: "what is exciting about this generation is how true it meets a clinical need.
"the device is fashionable and easy and maybe in the arms of surgeons in a short time." Trials
The generation has been tested on 253 samples as part of the observed. The plan is to maintain checking out to refine the tool earlier than trialling it at some point of operations next 12 months.
The pen currently analyses a patch of tissue 1.5mm (0.06in) across, however, the researchers have already developed pens that are even more subtle and should be able to have a look at a finer patch of tissue simply zero.6mm across.
Even as the pen itself is cheap, the mass spectrometer is high-priced and cumbersome. Dr Eberlin said: "the roadblock is the mass spectrometer, for positive.
Dr James Suliburk, one of the researchers and the pinnacle of endocrine surgery at Baylor College of drugs, stated: "any time we will provide the affected person an extra unique surgical operation, a faster surgery or a more secure surgery, it's something we need to do.
"this technology does all three.
The masspec pen is the ultra-modern try to improve the accuracy of surgical operation. A group at imperial college London have developed a knife that "smells" the tissue it cuts to determine whether it's miles casting off cancer.
And a crew at Harvard are using lasers to analyse how a whole lot of brain cancer to remove. Dr Aine McCarthy, from most cancers, studies united kingdom, said: "interesting studies like this has the capability to hurry up how speedy docs can decide if a tumour is cancerous or not and study its traits.
"accumulating this type of data speedy during surgical treatment may want to assist docs in shape the best remedy alternatives for patients faster."
