When the genetic material (DNA) of a cell becomes damaged or changed, it produces mutations that affect normal cell growth and division. When this happens, cells do not die when they should and new cells form when the body does not need them. The extra cells may form a mass of tissue called a tumour.
When these tumours becomes malignant, they become cancerous and can spread to other parts of the body.
