Breast Cancer Prevention and Screening
Breast Cancer Screening
Cancer screening exams are important medical tests done when you’re at risk but don’t have symptoms. They help find cancer at its earliest stage, when the chances for successful treatment are best. MD Anderson recommends the following screening tests for breast cancer:
Starting at age 20: Women at all risk levels for breast cancer should practice breast self-awareness. Be familiar with how your breasts look and feel and immediately report any changes to your doctor.
Starting at age 40: Women at average risk for breast cancer should begin getting annual mammograms and breast exams.

Breast Cancer Risk Factors
If you have any of the risk factors listed below, talk to your doctor about getting these tests more often and adding more tests, including breast MRI (magnetic resonance imaging) and genetic testing. If you are concerned about inherited family syndromes that may cause breast cancer, we offer advanced genetic testing to let you know your risk.
Anything that increases your chance of getting breast cancer is a risk factor. These include:
- Age: While most cases occur in women 50 or older, breast cancer sometimes develops in women in their 20s. Age is the main risk factor.
- Family history (especially mother, sister, daughter) of ovarian and/or breast cancer
- Hormones/childbirth: Your risk of breast cancer is higher if you:
- Had your first period before age 12
- Began menopause after age 55
- Never had children
- Had your first child after age 30
- Used hormone therapy after menopause
- History of radiation to the chest area
- Previous abnormal breast biopsy results
- Breast diseases such as atypical hyperplasia, or lobular or ductal carcinoma
- Obesity or weight gain after menopause
- Inherited susceptibility genes BRCA1 and BRCA2 account for about 5% to 10% of breast cancer cases. Tell your doctor if other women in your family have had breast cancer
Other breast cancer risk factors include:
- Oral contraceptive use (birth control pills)
- Diet high in saturated fats
- Not getting enough exercise
- Drinking more than one alcoholic drink a day
Not everyone with risk factors gets breast cancer. However, if you have risk factors, it’s a good idea to discuss them with your doctor.
