Breakthrough Breast Cancer

Breakthrough Breast Cancer was a United Kingdom charity whose mission was to "save lives through improving early diagnosis, developing new treatments and preventing all types of breast cancer". In 2015, Breakthrough Breast Cancer merged with another UK charity, Breast Cancer Campaign, to form the UK's largest breast cancer research charity - Breast Cancer Now. In 2019, Breast Cancer Care merged with Breast Cancer Now and the two organizations together became known as Breast Cancer Now.
