Prevention has to start with knowledge. Women at an increased risk of breast cancer may need to start screening earlier or be screened more frequently than women of average risk. You might be at an increased risk if you:
• Are overweight or obese or are not physically active
• Have mutations of BRCA-1, BRCA-2 or PALB-2 genes
• Have a family or personal history of breast, colorectal or ovarian cancer
• Began menstrual period before 12 or began menopause after 55
• Have never had children or had your first child after age 30
• Are currently using or have recently used birth control pills
• Have used hormone replacement therapy (with estrogen and progesterone) for more than 10 years
