As a charity, we rely on voluntary contributions to provide this information. This is done through clinical trials , or studies as they are sometimes called.
Trials compare new treatments with the best available standard ones.
Until the new treatment has been tested scientifically in this way it is impossible for doctors to know which is the best one to choose for their patients. If you do choose to take part in a trial, it is important to remember that whatever treatment you receive will have been carefully researched in preliminary studies. To take part in a trial, you must give your 'informed consent'. Informed consent means that you know what the trial is about, you understand why it is being conducted and why you have been invited to take part, and you understand exactly how you will be involved.
