The month of October is recognized as Breast Cancer Awareness Month. This health observance reminds us to be aware of the risk factors for developing breast cancer and the steps we can take to improve our health and possibly help lower the risk of getting breast cancer.
What is a digital mammogram?
A mammogram is a special type of x-ray that is used to examine breast tissue and help with the diagnosis of breast cancer and other breast conditions.
In digital mammography, x-ray beams are captured on specially designed digital detectors. The digital detector converts the x-ray beams into electronic signals, which are then sent to a computer. Our board-certified radiologists review digital mammograms on a high-resolution computer monitor.
Studies have shown digital mammography to be significantly more accurate than screen-film mammography in women with dense breast tissue and women who are premenopausal or perimenopausal.
When should I get my first mammogram?
For women at average risk for breast cancer, the American College of Radiology (ACR), the Society of Breast Imaging (SBI), the American Congress of Obstetricians and Gynecologists (ACOG), and the United States Preventive Services Task Force (USPSTF) all recommend screening be initiated at age 40. USPSTF recommendations are for biennial screening, ACOG recommends screening every 1-2 years, and SBI and ACR recommend annual screening mammography after 40.
Women with certain risk factors (such as family history, prior mantle radiation, or high-risk genetic mutations and some minority groups, including Black women and Ashkenazi Jewish women) may need to start screening at an earlier age.
Although breast cancer screening cannot prevent breast cancer, it can help find breast cancer early, when it is easier to treat. All women are encouraged to discuss an appropriate screening program and risk assessment with their clinician.
How should I prepare for a mammogram?
- Try not to have your mammogram the week before you get your period or during your period. Your breasts may be tender or swollen then.
- On the day of your mammogram, don't wear antiperspirant, powder, or cream under your arms because these may interfere with the quality of your mammogram.
- Wear a two-piece outfit since you will be asked to undress from the waist up.
Breast awareness and signs of breast cancer
Practicing breast awareness means knowing what is typical for your breasts and reporting any changes in your breasts to your provider. It is recommended that women check their breasts monthly, usually after their periods, and have a breast exam with their primary care provider annually. Breast-associated changes might include:
- Breast lumps or lumps in the armpit area, skin changes such as thickening of the skin or skin discoloration, bloody nipple discharge, or nipple inversion.
High-risk screening and genetic testing
Most breast cancer is not due to a gene; however, genetic testing is sometimes recommended for people who have a family history of cancer. If a genetic mutation is identified, it could mean that the person has an elevated risk for different types of cancer, including breast cancer. By identifying this risk, individuals can work with a specialist to determine an appropriate screening regimen and discuss additional preventative care.
Individuals with a family history of breast cancer, with or without genetic mutations, or with very dense breast tissue may benefit from enhanced annual breast cancer screening. This may include additional imaging, such as a breast MRI. Some women may consider a consultation with a specialist to discuss their individualized risk and determine an appropriate screening regimen.
