Cancer Research UK’s Signs and Symptoms app is designed to highlight some of the possible symptoms of cancer. When cancer is found at an early stage, treatment is often easier and more likely to be successful. So finding cancer sooner rather than later can make a real difference.

Cancer Research UK is the world's leading cancer charity dedicated to saving lives through research. Our groundbreaking work into the prevention, diagnosis and treatment of cancer has seen survival rates double in the last 40 years. But more than one in three of us will get cancer at some point in our lives. Our research, entirely funded by the public, is critical to ensuring more people beat it.
