What is cancer?

Cancer is caused by changes (mutations) damaging the genes (DNA) of a cell which the cell’s normal repair functions cannot correct. As a result of DNA damage, cells divide uncontrollably, become dislodged from the original tumour site and spread to other parts of the body (metastasis). This is the process which creates a cancerous tumour including billions of cancer cells.
 
There are several different types of cancers, which can be classified by their location or growth pattern:
