Delyth became Chief Executive of Breakthrough Breast Cancer in 1996, when the charity was in its infancy. Since then, she has been committed to stopping women dying from breast cancer, working at the forefront of this critical field in a number of different capacities.  

As CEO of Breakthrough for 10 years, she turned the organisation into the fastest growing charity in the sector and created a dynamic and ambitious brand that put breast cancer firmly on the public agenda.

In 2007, Delyth was appointed to Government. She served as Children’s Minister, Intellectual Property Minister and Quality and Government spokesperson for the Department of Work and Pensions in the House of Lords.

She became Chief Executive of Breast Cancer Campaign in 2011 which went on to become Breast Cancer Now, leading the charity in its mission to find the cures for breast cancer and conducting the first Gap Analysis to identify the critical gaps in breast cancer research and knowledge.

In 2019, Delyth was key in bringing together the merged charities of Breast Cancer Care and Breast Cancer Now, to form our new charity that is raising awareness, funding research, and providing crucial care for anyone diagnosed with breast cancer.
