Breast cancer self-checking device wins the UK James Dyson Award 2022

This year’s UK James Dyson Award winner attempts to solve the problems surrounding monthly breast self-checks.

The device aims to try and promote early detection of any suspicious lumps or abnormalities within the breast tissue.

Breast cancer is a global issue, and last year there were around 11,500 breast cancer deaths in the UK, which works out to 32 every day.

Breast cancer is currently the second most common cause of cancer death in the UK. Despite this, many women are failing to perform monthly checks.

Over half of women (64%) aged 18-35 admit they don’t conduct self-examinations on a regular basis. However, if breast cancer is detected at the earliest stage almost all women survive.

Recent graduates of Innovation Design Engineering at Imperial College London and the Royal College of Art, Debra Babalola and Shefali Bohra identified through their research that there are lots of different methods and conflicting information advising women to perform self-checks.

However, this contradictory information can often lead to women not performing routine checks all together.

So they decided to do something about it.

To solve these issues, Debra and Shefali created Dotplot, which is an at-home breast health monitoring tool that offers guided self-checks on a monthly basis.

It is designed to facilitate the early detection of breast cancer by enabling and encouraging women to stick to a regular breast-self check routine.

How does it work?

The user builds a personalised map of their torso by providing their bra size, breast shape and by sliding the handheld device to rescale the baseline model.

Once set up, the app guides women through the self-check by showing which areas they need to scan. A sound signal is emitted to record the tissue composition at each site. Each month’s reading is compared to the previously recorded readings to highlight any abnormalities developing in the tissue.

Users will be notified if there are any suspicious changes and advised to visit a healthcare professional for further investigation.

Debra and Shefali estimate that through early detection their device could save hundreds of lives each year.

They hope to develop the device further to be able to apply the technology to monitor for other tissue changes, such as those associated with testicular cancer and soft tissue sarcoma.

The story behind the invention

One day, Shefali discovered an unusual knot in one of her breasts after a gym workout. She approached a gynaecologist for a clinical breast exam, where a palpation test was performed, and she was advised to monitor the knot using her own fingers for a few months.

Fortunately, the knot self-resolved. Using this event as a starting point, Shefali and Debra sought to discover existing tools that routinely assist women in monitoring their breasts.

Astonished by the lack of at-home solutions for the early detection of breast cancer, they set their ambitions to build a product to address this need.

They went on to conduct interviews with women who do and do not have a family history of breast cancer to gather key insights on how they currently engage with self-checks.

Their research highlighted that even after a nurse or GP demonstrated a self-check, many women were still not certain that they were doing them correctly and current guidance for self-checks is limited to demos, tutorials, and pamphlets.

Furthermore, existing scanners and devices have been developed and designed for use within clinical settings and nothing exists to assist women in performing examinations from home.

Award winners

For the technical development, the team used sound waves to detect lumps within a breast surrogate and found clear differences in readings in areas with and without lumps.

On winning the James Dyson Award, Debra said: ‘Finding out that we had won the UK National James Dyson Award has been completely surreal.

‘Seeing previous projects that have won the award has been so inspiring for us and winning this really takes us to the next level of our development.

‘The goal is for Dotplot to make breast self-checks become routine for women across the globe and to help catch any suspicious changes as soon as possible.’

Shefali said: ‘We were shocked to discover that there are no products available that can assist women to carry out a breast self-check, so we set ourselves the goal of creating a device that can allow women to perform self-checks with clarity, ease and confidence.

‘Winning the James Dyson Award gives us the validation that Dotplot is an idea worth pursuing. You need that motivation at each and every point of product design, especially when you hit a low.’

Winning the national leg of the James Dyson Award will inject £5,000 into Dotplot’s project.

Debra and Shefali aim to commercialise their invention in the coming years, using the award money for further research and official medical testing into how the invention can become a global solution to at-home breast self-checks and hopefully save lives.

Dotplot will now progress to the international stage of the James Dyson Award.

The International shortlist will be announced on 12th October, and the International winners on 16th November.
