Avoiding risk factors and increasing protective factors may help prevent cancer.
Anything that increases your chance of developing cancer is called a cancer risk factor and anything that decreases your chance of developing cancer is called a cancer protective factor. Some risk factors for breast cancer can be avoided, but some cannot. For example, both smoking and inheriting certain genetic mutations are risk factors for some types of cancer, but only smoking can be avoided. While there is no sure way to prevent breast cancer there are things you can do to help lower your chance of getting breast cancer.
