Breast cancer is uncommon in women <35 years of age; the greatest
risk is for women aged 50-60.
Race: Breast
Cancer occurs more often in White women than in Black, Hispanic, or Asian
women.
Family

female relative has suffered from breast cancer, this increases your risk
factors for developing breast cancer.

have had significant exposure to radiation at a young age.
