It's hoped new technology created by a Kent woman will help more of us regularly check our breasts for signs of cancer.
Dotplot uses sound waves to monitor breast tissue - the details are saved in an app and compared each month.
The user will be alerted to any significant changes and urged to see a GP.
Debra Babalola from Bromley helped come up with the idea.
The tech has won this year's prestigious James Dyson Award.
