Many women who develop breast cancer do not have any known risk factors. Still, we know that women who possess certain risk factors are at a higher risk of developing breast cancer than the general population. Although some women who have one or more risk factors may never develop breast cancer, we can use the knowledge of these risk factors to target higher-risk women with increased breast surveillance and breast cancer prevention strategies. Certain, unavoidable risk factors — such as gender and age — make us all susceptible to breast cancer. Other risk factors, such as family history, are also factors that we cannot change.
Worldwide statistics on breast cancer
Genetics: Breast Cancer Risk Factors
Based on current incidence rates, This estimate means that, if the current incidence rate stays the same, a woman born today has about a 1 in 8 chance of being diagnosed with breast cancer at some time during her life. On the other hand, the chance that she will never have breast cancer is In the s, the lifetime risk of being diagnosed with breast cancer in the United States was just under 10 percent or about 1 in The last five annual SEER reports show the following estimates of lifetime risk of breast cancer, all very close to a lifetime risk of 1 in SEER statisticians expect some variability from year to year.
Breast Cancer Risk and Risk Factors
Breast cancer is the most commonly occurring cancer in women and the second most common cancer overall. There were over 2 million new cases in The Continuous Update Project Panel judged that there was strong evidence that consumption of alcoholic drinks, greater birthweight and adult attained height are causes of premenopausal breast cancer. The panel also judged that there is strong evidence that vigorous physical activity and greater body fatness protect against premenopausal breast cancer more information about this unusual finding on greater body fatness can be found in Appendix 2 of Body fatness and weight gain.
