The charity formed by the merger of Breast Cancer Campaign and Breakthrough Breast Cancer will be called Breast Cancer Now and use a new logo.
A statement from Breast Cancer Now said: "The charity's name conveys the urgency required to stop women in the UK dying from breast cancer, with its mark representing the endeavour, dedication and hearts of the supporters and researchers behind the charity's life-saving work." It said that BCN "has the ambition of stopping women dying from breast cancer by 2050".
The two charities, which have 212 staff and a combined income of £28.3m according to their most recent accounts, announced in November that they would merge. In March, Baroness Delyth Morgan of Drefelin, a crossbench peer who has previously worked for both charities, was named chief executive of the new charity.
Fiona Hazell, director of communications and engagement at BCN, said this was a new era for the charity. "We have the brightest scientific minds across the UK already working hard behind the scenes to discover how to prevent breast cancer, how to detect it earlier and how to stop it taking lives," she said.
