Are You at High Risk for Breast Cancer? Key Factors to Consider
Published: Apr 05, 2024
While all women are at risk for breast cancer, some factors significantly increase that risk. Understanding your personal risk profile can help guide screening and prevention strategies.

Genetic Factors
About 5-10% of breast cancers are thought to be hereditary. Mutations in the BRCA1 and BRCA2 genes are the most common cause of hereditary breast cancer. Women with these mutations have up to a 70% chance of developing breast cancer by age 80. Other genes like TP53 and PTEN can also increase risk.
Family History
Having a first-degree relative (mother, sister, daughter) with breast cancer approximately doubles your risk. The risk is higher if multiple relatives were affected or if they were diagnosed at a young age. Male breast cancer in the family is also a red flag for increased risk.
Personal History and Lifestyle Factors
Women who've had breast cancer are at higher risk of developing a second breast cancer. Other risk factors include: dense breast tissue, certain benign breast conditions, early menstruation (before age 12), late menopause (after 55), never having children or having your first child after age 30, long-term use of hormone replacement therapy, obesity (especially after menopause), and alcohol consumption.
Frequently Asked Questions

Some risk factors like diet and exercise can be modified.
Key Takeaways
While you can't change some risk factors, knowing your risk can empower you to take proactive steps for your breast health.
