I found this picture and article and then learned about the organization Worldwide Breast Cancer today. (I thought I knew about all breast cancer organizations, but obviously I am not as smart as I thought.)
It's not a new concept but it uses a dozen lemons to show what breast cancer can look like. Who knew it could be so easy to show women what to look for instead of thee vague 'something different'. This started 15 years ago and has been translated in 70 languages. And if you go deeper into their site you can see more in depth explanations.
