Worldwide Breast Cancer releases new Know Your Lemons® App because Breast Cancer Awareness doesn’t end Oct 31!


New Know Your Lemons® breast health app helps women find breast cancer better

Worldwide Breast Cancer has created a fun and engaging Know Your Lemons® mobile app for breast health. The app builds on their successful award-winning design and friendly lemon visuals seen by over 200 million people so far. Dogtown Media helped bring the app to life with its dedicated development team.

Why an app? Until we have a cure for breast cancer, according to the World Health Organization, early detection is key to improving a woman’s chance of survival.[1]

What makes a big impact on early detection? Education. To be at the forefront of healthcare communication, Worldwide Breast Cancer’s “Know Your Lemons” app aims to help more women around the world find breast cancer better. Through understanding screening and changes to look out for and report to a physician patients can be more empowered to take charge of their breast health.

Unlike any other breast health app, this new mobile tool doesn’t just help women “look for a lump” or “make sure you get a mammogram.” It also provides humorous video and audio guides on what to feel for, uses the famous Know Your Lemons® campaign to show the 12 symptoms of breast cancer in detail, demystifies screening techniques and makes it easy to book mammograms. For the first time ever, women can use an app to get a reminder AND book a mammogram!

 “At Worldwide Breast Cancer, our goal of educating every woman in the world about what to look and feel for, and steps to take if they think they have found a symptom is our primary focus,” says Corrine Ellsworth Beaumont, PhD., Founder, Worldwide Breast Cancer.

“Even though over 200 million people have seen our 12 lemons image so far, we dream of empowering 2.2 billion women with vital information, regardless of language, race or location, so they can get help in a timely way. While researchers are looking for breast cancer cures, we want to do everything we can to make sure every women has the best chance of survival. We believe our Know Your Lemons® app is a big leap forward for women everywhere in removing communication barriers that have prevented breast cancer from being discussed.”

The Know Your Lemons® app is backed by a decade of research and has been designed to address major gaps in breast health communication. Despite many awareness campaigns in the past, a 2017 survey of 19,000 women globally found just how lacking knowledge of breast cancer is: 

·       Only 2% of women can recognize all the signs of breast cancer

·       42% of women don't feel confident in their ability to spot a change indicative of breast cancer[2]

Key features of the new app to address this include:

  • Education about the symptoms of breast cancer and the difference between healthy and unhealthy lumps found in the breast

  • Exam coaches, such as Mona Lisa, who explains step-by-step how to self-exam in an entertaining and informative way

  • Booking mammogram or screening appointments with local FDA certified screening centers

  • Questions for users to ask clinicians or doctors at screening appointments, as well as advice on what (or not) to wear and how to prepare for different breast tests

The app is available for download on iTunes and Google Play under Know Your Lemons. It’s the must have app for every woman’s phone!

This app was made possible with support from Celgene, Avon Foundation for Women and Genentech.

About Corrine Ellsworth Beaumont, Founder

Corrine is the inventor of Know Your Lemons, an innovative campaign teaching about the symptoms of breast cancer and the process for detection. Her groundbreaking work is creating a new paradigm of breast health communication and has been viewed by over 200 million people worldwide. Because the familiar, friendly lemon crosses common healthcare communication barriers of literacy, taboo and fear, "Know Your Lemons" is the only truly global breast cancer education campaign.

Corrine’s passion for educating people everywhere is fueled from her grandmothers and a close friend dying of metastatic breast cancer. Driven to take action against the disease, she learned just about everything there is to know about breast cancer detection and treatment, and studied the psychological effects of healthcare communication. After receiving her PhD in design, Corrine took the findings from her doctoral dissertation, Design thinking in healthcare: developing patient-centred communication materials for breast cancer detection, and created Worldwide Breast Cancer.

In 2017, Corrine and Know Your Lemons were featured on CNN, BBC News, ITV, various radio stations and numerous publications in the health, beauty, medical and design fields. She holds a MFA and BFA in graphic design from Utah State University, as well as a PhD in design from Buckinghamshire University and Brunel University. She has held a variety of teaching positions at Kingston University and consulted with the healthcare industry.
