Think Before You Pink

Our work to end this breast cancer challenges "pinkwashing" hypocrisy and pink ribbon culture, which have become the status quo of the breast cancer industry.



We are radical and compassionate — activists at heart with an independent, rapid-response, watchdog perspective.
BCAction was founded 30+ years ago in San Francisco during two public health crises-the AIDS outbreak and the breast cancer epidemic-and that helped shape its mission and fuel its activism. Early members apprenticed themselves to the AIDS group, ACT UP, and shared many of that group’s tactics, turning their anger into action to push for better treatments, true prevention, and investment in public health.
Our founders saw their disease not as a personal tragedy, but as a larger social justice and public health crisis. They knew that individual changes in behavior weren’t the answer, and pushed for sweeping systemic change instead.

Think Before You Pink®

Breast Cancer Actions's Think Before You Pink campaign continues to hold the Breast Cancer Industry accountable

The absence of transparency, lack of accountability, and the widespread hypocrisy in the pink ribbon marketing culture exploits a disease that devastates communities, misrepresents who is affected by breast cancer, and excludes and marginalizes women’s diverse lived experiences of the disease
