Cancer

Cancer occurs when the body's cells begin to grow in an abnormal and uncontrolled way. These rogue cells can invade nearby tissues and may spread to other parts of the body if not treated.

What is cancer?

Cancer is a group of diseases that happen when cells in the body grow and divide uncontrollably. This can lead to the formation of tumours, which are lumps of tissue that can be either benign (not cancerous) or malignant (cancerous).
