What is Cancer?
To understand cancer we have to have some appreciation of human biology. Our body is made up of minuscule entities called cells; these are the basic unit of life. Similar types of cells come together to form our tissues (e.g: muscle tissue, brain tissue etc), groups of tissues form our organs and then organs come together to form systems (e.g: cardio- vascular system, nervous system). Cancer is a disease of the smallest unit of our body – the cell. It develops when cells within our body obtain a series of defects that result in their uncontrollable growth. These cells are thus able to grow and divide into multiple defective cells that form a mass called a tumour.
