"70% to 80% of women who get breast cancer do not have a family history of this disease"

While family history increases one's likelihood of developing breast cancer, 70% to 80% of women who get breast cancer do not have a family history of this disease.

Therefore, regardless of family history, it is important for all women to stay up to date with clinical breast exams and mammograms. Your doctor can advise you on when, and how often, to schedule these exams.
