Your doctor may suggest a clinical trial if it could offer access to new or improved treatments. Talking with your specialist, GP, or seeking a second opinion can help you decide whether a trial feels right for you. You can join a clinical trial through a referral from your treating doctor. They can check which trials are currently recruiting and whether you may be eligible. If a suitable option is available, they can refer you to the hospital running the study.
You can also look for trials online, but these sites can be hard to navigate -especially for people with a suspected cancer. Many trials have strict eligibility requirements, such as needing a known primary cancer site or a specific genetic mutation.
It’s best to discuss any trial you find with your treatment team. They can help you understand your options and guide you through the process.
Taking part in a clinical trial is completely voluntary. If you choose to participate, you can change your mind and withdraw at any time.
Clinical trials are a vital part of cancer research. They help doctors and scientists learn which treatments work best and are safest - not just for medical treatments, but also for psychological and supportive care. Over time, clinical trials have led to better treatments and improved outcomes for people diagnosed with cancer.
One common type of trial is a randomised controlled trial. In this kind of study, participants are randomly assigned to receive either the current best treatment or a new treatment. This helps researchers find out if the new approach works better.
Clinical trials can test many different types of interventions, including:
Clinical trials are often completed in phases, starting from a small number of participants and increasing the number during each phase.
There are four main phases of clinical trials:
