Am I at High Risk for Breast Cancer?

Who is at high risk for breast cancer — and which risk factors can you control?

Because of certain risk factors, some women have a higher chance of developing breast cancer than others. While some risk factors are not in your control, others are more manageable.

The breast health experts of USC Norris Comprehensive Cancer Center, part of Keck Medicine of USC, share which risk factors to watch for, plus what steps you can take to stay in good health.

Breast cancer risk factors that can’t be changed

• Getting older
• Family history
• Starting your period before age 12
• Going through menopause after age 55
• A history of certain breast conditions
• Having dense breasts
• Radiation therapy to the chest before age 30

Breast cancer risk factors you may be able to control

How active you are: Exercise reduces the risk of breast cancer, so talk to your doctor about a fitness plan that would work best for you.

Weight: Being overweight increases breast cancer risk. If you struggle with your weight, talk to your doctor about the best course of action for your health.

Estrogen and progesterone: Having higher levels of estrogen and progesterone has been linked to increased risk of breast cancer.

Reproductive history: If you haven’t had children, you may have a higher risk of breast cancer.

Pregnancy age and breastfeeding: Having children later can increase your risk of breast cancer, but breastfeeding can reduce your risk.

If you think you might be at high risk for breast cancer, don’t panic. There are many interventions that can help, including genetic testing, seeing a high-risk specialist and starting mammograms earlier than an average-risk patient.

The specialists at USC Norris can help bring you peace of mind with expert guidance on prevention. They’re also equipped with the latest mammography and ultrasound technology, ensuring that even if you do develop breast cancer, it will be caught in its earliest stages when it’s easiest to treat.
