BREAST CANCER: WHO IS AT RISK?
The exact cause of breast cancer is as yet unknown. Doctors can seldom explain why one woman gets breast cancer and another does not.
What is known

Risk Factors
A Risk Factor is anything that increases a person's chance of developing a disease. Risk factors for the development of breast cancer include (not in any particular order)

Remember!
Many risk factors can be avoided. Others, such as family history, cannot be avoided. It is helpful to be aware of risk factors. But it is also important to keep in mind that most women who have these risk factors do not get breast cancer. Also, most women who develop breast cancer have no history of the disease in their family. In fact, except for growing older, most women with breast cancer have no strong risk factors.

However, any woman who thinks she may be at risk of breast cancer should discuss her concerns with her GP.
