Understanding Breast Cancer

Our body is made up thousands of cells that differ in size, shape and function. Controlled by our DNA, each cell is programmed to perform certain tasks and after a specified period of time - die. This is normally done in an orderly manner. However, if our cells are exposed to carcinogens, viruses or ionizing radiation, for example, the DNA can become damaged creating havoc with this once orderly process. Said another way, if the rate of new cell growth in the body overcomes the rate of cell death, tumors can develop.
