Causes of Breast Cancer

No one knows for certain what causes breast cancer. However, a number of risk factors are known to increase the chance of developing breast cancer - but these does not necessarily mean that a person will get the disease.

There are different kinds of risk factors. Some of these factors are beyond control, while some are linked to cancer-causing factors in the environment or due to lifestyle and personal choices such as pregnancy, smoking, and drinking.

• Risk factors that you cannot change
