Our take
The world’s largest independent cancer research charity, Cancer Research UK (CRUK) was founded from a merger between the Cancer Research Campaign and the Cancer Research Fund in 2002. CRC and ICRF had been long-standing pinnacles of the British medical institution, their work dating back to 1902 and 1923 respectively, and the merger signalled a strong step forward for UK medical institutes’ global influence.
A multi-armed charity, CRUK uses both grant-funded researchers and its own employed staff to research the treatments and causes of cancer, whilst its striking advertising and marketing campaigns are responsible for influencing public policy on the causes, prevention, and treatment of the disease. An example of a significant public campaign was Stoptober, which appeared to have triggered a third of a million smokers at the time to try quit tobacco throughout the month of October.
Alongside its pharmaceutical efforts, in 2023 CRUK funded clinical trials for the first-ever proton beam therapy for breast cancer, indicating a focus on technological innovations in the fight against cancer. On this subject, CRUK has also taken part in a billion-pound investment in the Francis Crick Institute, a biomedical research institute that is aiming to make England an international leader in the industry.
