Breast cancer
Researchers around the world are looking at ways to prevent, diagnose and treat breast cancer. Research includes gene changes, screening, new treatments and side effects.
Find out how Cancer Research UK researchers are discovering new ways to tackle breast cancer.
Our clinical trials database has information about UK clinical trials for breast cancer and summaries of trial results.
Clinical trials aim to improve diagnosis and treatments and reduce side effects. All cancer treatments have to be fully researched before everyone can use them. This is so we know that they work and are better than the treatments already available. And that they are safe.
