Our bodies are made up of billions of cells. Normal, healthy cells grow and multiply at a steady, controlled rate. In cancer, some of these cells start to multiply uncontrollably. They do not function normally and form a growth called a tumour.

1. Not all tumours are Cancer

Tumours may be benign or malignant. A benign tumour is not a cancer. It can crowd out healthy cells but does not spread to other parts of the body.

A malignant tumour is a cancer. It can invade nearby tissues and organs. It can also spread to other parts of the body to form new tumours.

2. Not all Cancers are the same

Cancer is a group of diseases that have one thing in common: the uncontrolled growth of abnormal cells and their spread throughout the body.

There are as many types of cancers as there are different types of cells in the body.
