Research has found several risk factors that may increase your chances of getting breast cancer.
Reproductive risk factors
Being younger when you first had your menstrual period
Starting menopause at a later age
Being older at the birth of your first child
Never giving birth
Not breastfeeding
Long-term use of hormone-replacement therapy
Other risk factors
Getting older
Personal history of breast cancer or some non-cancerous breast diseases
Family history of breast cancer (mother, father, sister, brother, daughter, or son)
Treatment with radiation therapy to the breast/chest
Being overweight (increases risk for breast cancer after menopause)
Having changes in the breast cancer-related genes BRCA1 or BRCA2
Drinking alcohol (more than one drink a day)
Not getting regular exercise
Having a risk factor does not mean you will get the disease. Most women have some risk factors and most women do not get breast cancer. If you have breast cancer risk factors, talk with your doctor about ways you can lower your risk and about screening for breast cancer.
Prevention
You can help lower your risk of breast cancer in the following ways:
Get screened for breast cancer regularly. By getting the necessary exams, you can increase your chances of finding out early on, if you have breast cancer.
Control your weight and exercise. Make healthy choices in the foods you eat and the kinds of drinks you have each day. Stay active.
Know your family history of breast cancer. If you have a mother, sister, or daughter with breast cancer, ask your doctor what is your risk of getting breast cancer and how you can lower your risk.
Find out the risks and benefits of hormone replacement therapy. Some women use hormone replacement therapy (HRT) to treat the symptoms of menopause. Ask your doctor about the risks and benefits of HRT and find out if hormone replacement therapy is right for you.
Limit the amount of alcohol you drink.
