Four months after Corrine Ellsworth Beaumont resigned from her job to focus on the nonprofit she founded, her phone buzzed—it didn’t seem to stop for three weeks. 

“I wasn’t prepared for the amount of press I got in those first three weeks,” says Beaumont, founder of Worldwide Breast Cancer and creator of the “Know Your Lemons” campaign. “I would see inquiries coming in from Germany one day … then I’d see stuff coming in from Italy and Thailand. I had people contacting me on Facebook, saying they’d seen my stuff in Paraguay.”

Since 2003, Beaumont had been working on “Know Your Lemons,” a visualization of breast cancer symptoms represented by a dozen lemons in an egg carton. One day in January 2017, the campaign went viral.
