Overview
Keep A Breast Foundation, commonly known as Keep a Breast or KAB, is a United States 501(c)(3) nonprofit organization working in breast-cancer prevention, education, and early detection. It was founded in 2000 by Shaney Jo Darden and Mona Mukherjea-Gehrig, whose work grew out of art, fashion, and action-sports communities in Southern California. Rather than presenting breast cancer only through clinical or fear-based messaging, the organization developed a deliberately accessible cultural approach intended to make conversations about breast health more approachable for younger audiences. The founders' collaboration began before the nonprofit was formally established. In 1998, Darden and Mukherjea-Gehrig organized events that brought together friends, coworkers, local young people, and artists from street-art, fine-art, fashion, and action-sports circles. After an acquaintance of Darden was diagnosed with breast cancer in 2000, they adapted this event model toward breast-cancer awareness. That year they developed a process for creating breast casts that could be individually decorated by artists, and they held their first breast-cast auction. Subsequent exhibitions and related events included projects in Tokyo, Portland, Bordeaux, and other art, retail, and cultural settings. KAB obtained formal nonprofit status in 2005. In 2008, Darden left her employment to work for the foundation full-time, and the organization moved from her home into an office in Carlsbad, California. The foundation later became associated with a broad range of awareness merchandise, educational materials, touring events, social-media activities, and partnerships with commercial and cultural organizations. Its work has reached audiences through music festivals, action-sports events, retail collaborations, online content, and international affiliates. One of KAB's best-known initiatives is the Check Yourself program. It promotes breast-health awareness and encourages regular self-checks through printed materials, online education, blogs, and the Check Yourself! mobile application. The app is designed to explain the self-check process and provide recurring reminders. The related #checkyourselfie campaign used social media to encourage people to share the prevention message and direct others toward the app. The foundation's "I love boobies!" message, introduced in 2008, became its most recognizable public-awareness platform. Silicone bracelets and other merchandise used the phrase to address breast health in language intended to feel direct, informal, and less intimidating to young people. Merchandise revenue has supported KAB's programs and outreach. The bracelets also led to a legal dispute when some United States schools prohibited students from wearing them under dress codes governing sexual language or imagery. The Third Circuit held that the bans violated students' free-speech rights, and the United States Supreme Court declined to hear the subsequent appeal. KAB also operates or has operated programs addressing people living with breast cancer and environmental risk. Treasured Chest gives eligible women, including those diagnosed with breast cancer or testing positive for BRCA1 or BRCA2 mutations, an opportunity to create a breast cast. Non-Toxic Revolution promotes public education about potentially harmful chemicals in food and the environment, especially chemicals discussed in relation to breast-cancer risk. Other initiatives have included DIY Action, Fit 4 Prevention, Imagine If..., and This Is My Story. The foundation has participated in the Vans Warped Tour since 2001 and continued through the tour's final edition in 2018. Its touring presence combined educational materials, volunteers, support, and merchandise, and included collaborations connected with the tour such as Check Yourself! Vol. 1 and Music for Boobies. KAB has also worked with brands and organizations including Rastaclat, HUF, True&Co., Valiant Entertainment, S.W. Basics, and…
History
Keep A Breast Foundation emerged from the creative and action-sports communities of Southern California. Shaney Jo Darden and Mona Mukherjea-Gehrig began organizing art and fashion events in 1998, initially presenting work by friends, colleagues, local youth, and artists from street-art and fine-art circles. The events were influenced by the founders' interest in bringing people together through progressive art and cultural programming. In 2000, after a friend of Darden was diagnosed with breast cancer, the pair redirected this community-building model toward breast-cancer awareness. They developed a technique for producing breast casts that could be customized by artists and organized their first breast-cast auction. The format became a distinctive part of the foundation's identity, allowing breast-cancer education and fundraising to be connected with artistic expression rather than presented only through conventional medical communications. Later exhibitions and projects appeared in locations and venues including Tokyo, Portland, Bordeaux, American Rag, Bare Minerals, and the Snow Show. The organization formally became a nonprofit in 2005. Darden left her job in 2008 to work for the foundation full-time, after which the operation moved from her home to an office in Carlsbad, California. During this period KAB expanded its use of merchandise, events, educational materials, and partnerships to reach younger people. Its most visible phrase, "I love boobies!", was introduced in 2008 as a deliberately lighthearted and shame-free way to begin conversations about breast health. Bracelets and other products bearing the phrase became popular among teenagers, while proceeds helped fund the foundation's programs and outreach. The bracelet campaign also generated a significant free-speech controversy. Several school districts prohibited students from wearing the bracelets because administrators considered the wording inconsistent with school dress codes. Litigation eventually reached the Third Circuit, where the court held that the bracelets represented protected expression about a social issue and were not plainly offensive or disruptive in the relevant school context. The Supreme Court declined to take up the case. Darden discussed the campaign and its controversy in a 2011 TEDx talk. KAB's educational portfolio developed beyond the bracelet campaign. Check Yourself provides printed and digital information encouraging regular breast self-checks, and the Check Yourself! app explains the process and allows users to set monthly reminders. Treasured Chest offers breast-cast kits and a creative support opportunity for women diagnosed with breast cancer or testing positive for BRCA1 or BRCA2 mutations. The kits have been distributed throughout the United States, including to many women under 40. Non-Toxic Revolution focuses on informing young people about potentially hazardous chemicals in food and the environment and their possible relationship to breast-cancer development. The foundation has also used participatory and community-based campaigns. DIY Action enables supporters to organize their own fundraisers with KAB educational materials and awareness merchandise. Fit 4 Prevention links physical activity and wellness with cancer-risk reduction. Imagine If... invited young people to reflect on a world without cancer through traveling education booths at tours, festivals, and events. This Is My Story collected written and video accounts from people affected by breast cancer and shared them through online channels. From 2001 through the last Vans Warped Tour in 2018, KAB maintained a presence on the tour with a staffed educational tent, volunteers, merchandise, and support resources. It also participated in creative collaborations involving touring artists, including Check Yourself! Vol. 1 and Music for Boobies. Other partnerships have involved Rastaclat, HUF, True&Co., Valiant Entertainment, S.W. Basics, and Thrive Causemetics. The foundation has developed an international network with affiliates reported in Japan, Canada, Europe, Mexico, and Chile. KAB Europe operates from Bordeaux, France, under the leadership identified in reference material as global CEO Lorene Carpentier. Across these activities, the organization has maintained a recognizable model that combines prevention education, early-detection awareness, creative culture, and community participation.
