Dr Simon Vincent, director of research, support and influencing at Breast Cancer Now, said:
"With over 55,000 people being diagnosed with breast cancer every year in the UK, and 11,000 sadly dying from the disease, research looking at how we can better detect and treat breast cancer is urgently needed.
"While this new technology could offer a new way to monitor the growth of breast cancer tumours and we look forward to seeing the final results, the device has not yet been tested on people and there’s a lot more we need to understand before we can consider whether or not it could be used in medical settings.
"Anyone affected by breast cancer can speak to Breast Cancer Now’s expert nurses by calling our free helpline on 0808 800 6000 for information and support.”
