Cancer Symptoms

Spotting cancer early means treatment is more likely to be successful. 

One in two people will develop some type of cancer during their lifetime.

There are hundreds of different types of cancer, making it hard to be aware of each one, but having a basic understanding of the four most common types in the UK – breast, lung, prostate and bowel cancer – is a good place to start.

How does cancer cause signs and symptoms?

A cancer can grow into, or begin to push on nearby organs, blood vessels, and nerves. This pressure causes some of the signs and symptoms of cancer.
