What is cancer?

Cancer is when certain cells in the body grow and divide in an uncontrolled way. These cells can invade and destroy surrounding tissues.

Sometimes the cancerous cells can spread (metastasize) from one part of the body to another. In most cases, the earlier the cancer is found, the more successful the treatment is. 

There are over 200 different types of cancer. You can find out about some of the more common types, different treatments and ways to cope with cancer by following the links on the cancer landing page.
