Scientists at the ICR are increasingly using non-invasive methods to measure the size of tumours in mice – allowing the same mouse to be assessed several times and reducing the overall numbers.

SEARCHBreast is a resource to facilitate sharing of archived material derived from in vivo breast cancer models.

On this page you will find analysis of global research on preventing cancer. We analyse this research so you have access to the best cancer prevention advice in the world.

Excellent standards of animal care are fully consistent with the conduct of high quality cancer research.

FRAME is dedicated to the development of new and valid methods that will replace the need for laboratory animals in medical and scientific research, education, and testing. Where the use of animals is currently necessary, FRAME supports the reduction of numbers involved to an unavoidable minimum and refinement of experimental procedures to minimise any suffering caused. The E-learning resource of FRAME has been set up to provide teachers, school children, students and general supporters with information about the different areas of animal experimentation and with specific resources as to how it can be reduced, refined or replaced. 

Humane Endpoints Website is provided by 3Rs-Centre Utrecht Life Sciences, gives insight into the recognition and application of humane endpoints in rodents. The website contributes to refinement, the prevention of unnecessary suffering in laboratory animals, by offering information, videos and photographs of rodent species. In addition, the website provides free training modules (accessible after registration). The site is currently available in EN, NL and FR. DE and ES will follow soon.

The aim of "InVitroJobs" is to enable researchers to access this branch of research more easily. Alongside the job search portal, the site maintains an up-to-date list of research groups active in the development of animal-free techniques. The primary aims of this list are to advertise job vacancies, to provide students with the opportunity to contact these research groups directly to obtain information for thesis assignments and to promote cooperation, networking and the exchange of ideas between researchers. 

A mainly government funded body which provides input to the UK’s Three Rs agenda, carries out research and provides funds for Three R research.
