What is Cancer?
Cancer is a group of more than 100 related diseases that occur when abnormal cells divide and destroy surrounding tissues. It can begin in any organ or tissue of the body. When cells keep dividing, the result is a mass of cells called a tumour. Benign tumours do not spread to other parts of the body, while malignant tumours do spread cancer to other body parts.
They eventually crowd out nearby normal cells and disrupt their function. The cause of most cancers is not fully understood. However, a combination of genetics and environmental factors usually contributes to the transformation of cells from normal to cancerous. Cancer may take years to develop.
The earlier cancer is detected, the more likely it is to be treated successfully.
