A new technique for breast screening using radio waves goes on trial in the UK.
The new technology costs a fraction of existing X-ray mammogram machines, takes just two minutes and totally removes the risk from exposure to radiation.
It could be used to routinely screen women at a much earlier age because there is no radiation risk.
The breakthrough raises the possibility that mass cancer screening could be extended to women in their 40s or even 30s and drastically improve survival rates.
Dr Ian Craddock, who developed the test at Bristol University, said the ultimate aim is to get mass breast screening into GPs' surgeries - and possibly even the High Street.
In Britain, the High Street is usually a focal point for shops and retailers in the city centre, and is most often used in reference to retailing.
Dr. Craddock said: "It could be put in a corner of a surgery or a private clinic or even on the High Street and it should transform how we screen for breast cancer.
"It's fast and relatively cheap and it makes spotting tumours much easier. We're very excited."
Breast cancer tests are only standard for women over 50 because x-rays cannot penetrate the firmer breast tissue of younger women.
But the new machine uses sound waves which can easily scan denser tissue.
The technology is called Maria, which stands for Multi-static Array processing for Radio wave Image Acquisition, reports Daily Mail.
