Diane's Story
From one diagnosis to a national movement
In 1996, breast cancer caught Diane Proulx Guerrera completely by surprise. There was no pain, no symptoms, and no warning. Following a biopsy, lumpectomy, chemotherapy, and radiation, Diane was declared cancer free.
She was deeply grateful for the research, treatment, and care that had saved her life—but she also understood how fragile access to that care could be. Diane and her husband believed that continued investment in research and treatment was essential to improving outcomes for others facing breast cancer.

Founded in October 1996, CURE began with a simple but powerful goal: to ensure that funding would always be available to support breast cancer research, medical equipment, and patient care.
What started as a personal commitment quickly grew into a shared responsibility. In 1997, CURE launched National Denim Day—an inclusive, grassroots initiative that invited Canadians from all walks of life to participate. By wearing denim at work in support of the cause, individuals and organizations across the country came together around a common purpose: improving the future for those affected by breast cancer.
Over time, this collective effort grew into a nationwide movement.
Since its inception, CURE raised close to $30 million to advance breast cancer research, education, and the purchase of vital medical equipment. Hundreds of thousands of Canadians have taken part—each contribution helping to strengthen care, expand knowledge, and move us closer to better outcomes.
What began with one woman’s diagnosis has become a lasting legacy of compassion, action, and hope—one that continues to shape CURE’s work today.
