Facts about Breast Cancer in the United States

Good News about Breast Cancer Trends
In recent years, perhaps coinciding with the decline in prescriptive hormone replacement therapy after menopause, we have seen a gradual reduction in female breast cancer incidence rates among women aged 50 and older. Death rates from breast cancer have been declining since about 1990, in part to better due to screening and early detection, increased awareness, and continually improving treatment options.
Factors That Decrease Breast Cancer Risk
- Being older when you first had your menstrual period.
- Starting menopause at an earlier age.
- Giving birth to more children, being younger at the birth of your first child, and breastfeeding your children.
