About World Breast Cancer Research Day
World Breast Cancer Research Day is observed annually on August 18 to focus attention on breast-cancer research. The campaign says it was founded in 2021 by the Dr Susan Love Foundation for Breast Cancer Research.
The current campaign site is associated with Tower Cancer Research Foundation, which says the Dr Susan Love Foundation’s mission continues through the Dr Susan Love Fund following a 2024 organizational transition.
Why World Breast Cancer Research Day matters
The day is designed to keep research visible outside the better-known October awareness period. Its campaign framing can support education and fundraising, but it should not be used to promise that a particular study, donation or treatment will produce an individual outcome.
For medical and research information, authoritative sources such as the U.S. National Cancer Institute provide appropriate context on ongoing breast-cancer research.
