What is a mammogram?
A mammogram is a type of medical imaging test used to examine breast tissue for lumps, masses or abnormalities. This test is done using low-dose X-rays to create images of the breast tissue, which are examined to detect any issues in the breast.
Mammograms are an essential part of your wellness routine because they can help detect a problem, even before a lump can be felt. Early detection of any issue is key to improving the chances of successful treatment.
There are two primary types of mammograms: screening and diagnostic.
Mammogram screening recommendations
We support recommendations that women of average risk for breast cancer begin annual screening mammograms at age 40. Baylor Scott & White Health encourages you to discuss the benefits, risks, and limitations of mammograms with your doctor.
The American Cancer Society recommends that women who are at high risk for breast cancer get a breast MRI and a mammogram every year, typically starting at age 30. This includes women who have:
- A family history of breast cancer
- A BRCA1 or BRCA2 gene mutation discovered through genetic testing
- A parent, sibling or child with a BRCA1 or BRCA2 gene mutation, but have not had genetic testing themselves
- Certain genetic syndromes or close relatives who have one of these conditions

Breast cancer risk factors
There are several factors that can increase your risk of developing breast cancer. Some of the most significant include:
- Age: The risk increases as a woman gets older, with most cases occurring in women over the age of 50. Because of this, it’s important to start regular mammograms at age 40 so your doctor can establish a baseline and monitor for changes over time.
- Family history: Women with a close relative (mother, sister or daughter) who has been diagnosed with breast cancer are at higher risk of developing the disease themselves, especially if the relative was diagnosed at a young age or if multiple relatives are affected.
- Personal history: Women who have previously been diagnosed with breast cancer, especially if they were diagnosed at a young age, are at higher risk of developing the disease again.
- Dense breast tissue: Women with dense breast tissue, as seen on a mammogram, are at higher risk.
- Hormonal factors: Women who began menstruating before age 12 or who have gone through menopause after age 55 are at higher risk. Additionally, women who have taken hormone replacement therapy (HRT) for an extended period may have an increased risk.
- Lifestyle factors: Obesity, lack of physical activity, excessive alcohol consumption and smoking have all been associated with an increased risk.
- Genetic mutations: Certain genetic mutations, such as BRCA1 and BRCA2, significantly increase a woman's risk.
It's important to note that having one or more of these risk factors does not necessarily mean that you will develop the disease. However, if you have any of these risk factors, you may need to be screened more frequently or at an earlier age than those without risk factors. It's important to discuss your individual risk factors and screening schedule with your doctor so you can have peace of mind about your future health.
Preparing for your mammogram
Getting a mammogram can make some people anxious, but knowing what to expect and how to prepare can help you feel confident walking into your mammogram appointment. During the mammogram, a technologist places each breast between two metal plates, then takes pictures from different angles. Once the mammogram is complete, the technologist reviews the images to make sure they are clear and show the entire breast.
The procedure typically takes about 15-30 minutes. While the mammogram itself is brief, you may need to wait for a few minutes before or after your imaging. Some people find that bringing something to read, music to listen to or a craft like knitting helps them pass the time and relieve any stress they may be feeling.
After the mammogram, the images are examined by a radiologist, who sends a report to your doctor. If a suspicious area is identified, further testing, such as additional mammograms, may be recommended.
Steps to make your mammogram go more smoothly
- Schedule your appointment for a time when your breasts are least likely to be tender—usually a week or so after your period.
- Skip deodorant, lotions and powders on the day of your mammogram. Chemicals in these products can interfere with the quality of the images.
- Wear a comfortable two-piece outfit to your screening. You’ll need to undress from the waist up, so choose a top that’s easy to take off and put back on.
- If you’ve previously had a mammogram at another medical facility, bring those images with you or have the other facility send them prior to your appointment. Comparing your old films to your new ones can help the radiologist detect changes in the breast tissue.
- Don’t forget to bring identification, like a driver’s license or other government-issued ID, and proof of insurance.

- Ultrasound-guided biopsy
- Stereotactic breast biopsy
- Breast MRI
An ultrasound-guided biopsy is a relatively quick, minimally invasive and low-risk procedure to sample a suspicious spot that is visible by ultrasound within the breast.
This type of needle biopsy samples tissue from an abnormal area in your breast that was found on your mammogram to determine the cause. It is usually recommended when the suspicious spot cannot be felt and is not visible on an ultrasound.
Magnetic resonance imaging is a non-invasive procedure that uses strong magnets and radio waves to create images of breast tissues and blood flow. Breast MRIs sometimes find abnormal areas not seen on mammography or sonogram.
