With breast cancer on the rise in young women, the Know Your Lemons app is closing the gap on late detection

SALT LAKE CITY, Oct. 16, 2026 /PRNewswire/ -- In honor of Breast Cancer Awareness Month, the global charity Know Your Lemons Foundation, announced a groundbreaking update to their Webby award-winning Know Your Lemons app to help improve early detection for women. This is part of the launch of the #Lemonista movement, a new initiative designed to improve confidence in self-exam, and assess an individual's risk to create a custom screening plan using an app for the first time.

The app update and #Lemonista movement launch marks the next chapter for the charity that has already reached 2 billion people worldwide with a life-saving breast cancer awareness campaign, including Lynsey White, age 24, who discovered a lump under her armpit just a week after seeing the Know Your Lemons' 12 symptoms image from social media. Within a few weeks she was diagnosed with breast cancer, but she met roadblocks in getting testing. 

"I was initially told it was nothing to worry about because I was so young. But Know Your Lemons gave me the confidence to advocate for myself and get the testing I needed. This is why it's so unbelievably important to promote Know Your Lemons and make sure that people know what to look out for, so they can get detected early," Lynsey says.

Lynsey is among a growing number of women under 40 discovering breast changes themselves, often before they are eligible for routine screening. Currently, breast cancer is the leading cause of cancer death among women ages 20 to 49 in the United States and the leading cause of cancer death among women globally.

One of the strongest predictors of surviving breast cancer is how early it is found. Yet most women have never been taught how to confidently check their breasts, and few have completed a risk assessment to determine when and how they should be screened—something the American College of Radiology recommends by age 25.

The Know Your Lemons app addresses both gaps through a new series of games that makes learning easy, engaging, and rewarding by earning two lemons in the app: one representing Confidence in knowing their body and the other representing Intelligence in knowing their personal risk and screening plan. When the two lemons are earned, they officially become a Lemonista.

Lemonistas then show their improved breast cancer awareness status by sharing the [two lemons] symbol on social media, transforming individual action into a visible global movement—and encouraging others to take charge of their breast health, too. Among others, CBS's Elsbeth actor Carrie Preston, Christine Handy of the Hello Beautiful movie, and breast cancer radiologist Dr. Anjali Malik have endorsed the movement by adding [two lemons] to their social media profiles. 

"So often we don't learn about breast health until we have a breast problem," said Corrine Ellsworth-Beaumont, founder of Know Your Lemons. "Every Lemonista who shares what they've learned has the power to help someone else catch something early, the way Lynsey's story shows us that we can make all the difference."
