Screening saves lives

Talk with your clinician about starting mammograms (often around age 40, earlier if high-risk)
Know your personal and family history, including genetic risk (e.g., BRCA)
Report any new lump, skin change, or nipple change promptly
High-risk patients may benefit from additional imaging such as MRI

Lower your risk

Stay physically active and maintain a healthy weight
Limit alcohol
Discuss the risks and benefits of hormone therapy with your clinician
Breastfeed if you can, which modestly lowers risk

If it's found early

Early breast cancers are usually treated with breast-conserving surgery and radiation, with excellent outcomes — and modern radiation is shorter and gentler than ever.
