Mammograms: What You Need to Know
A mammogram is a specialized type of X-ray that uses low doses of radiation to check the health of your breasts. It helps doctors spot any changes or problems, such as lumps or abnormalities even before you notice them, or symptoms begin to appear. It is a quick and typically easy test that can play a big role in catching breast cancer early, when it is easiest to treat.
One of the best ways to catch
breast cancer
early is by having mammograms every year after age 40 — or
earlier, if you have a family history
. That’s because a mammogram can find breast cancer up to two years before a lump is large enough to feel. Early detection of breast cancer is important because it often means you are more likely to have treatment options that are less aggressive, while still maintaining positive treatment outcomes.
What Is a Mammogram
Mammography is the best tool for doctors to find breast cancer, as it captures crisp, digital X-ray images of the breasts and breast tissue that can help radiologists locate anything from benign cysts to
cancer
. There are
two types of mammograms
used to detect cancer:
screening mammograms
and
diagnostic mammograms

Different Types of Mammograms & Imaging
At
Houston Methodist Breast Care Centers
, we perform both screening and diagnostic mammograms — using the most advanced imaging technology available — depending on a patient’s medical history and breast symptoms. We also perform breast ultrasounds, breast magnetic resonance imaging (MRI) and molecular breast imaging (MBI).
Screening Mammograms
Diagnostic Mammograms
Screening Mammograms
screening mammogram
is a relatively quick (20 to 30 minutes) r
outine low-dose X-ray
used to spot signs of breast cancer early, before any symptoms or lumps are felt. At Houston Methodist, our
board-certified radiologists
use
advanced 3D technology
to detect the smallest lumps and abnormalities with accuracy.
Breast cancer screening through
3D digital mammograms
— also known as
digital breast imaging
digital mammography
or
breast tomosynthesis
— provides the clearest pictures of your breasts, reducing the chance of being called back for follow-up imaging and improving the chance of catching breast cancer as early as possible.
Generally, if the radiologist finds anything concerning with your mammogram, you will be notified right away. If everything is normal, you should receive your report within a few days.

Diagnostic Mammograms
Diagnostic mammograms
are used to both find and rule out breast cancer.  A diagnostic mammogram may be recommended after a screening mammogram shows an abnormal result, or you if you have a breast lump, focal pain or nipple discharge or have had an abnormal mammogram.
Some women get called back to have a diagnostic mammogram after a screening mammogram. While unsettling, it is most often just precautionary. Women with
dense breasts
also may need a
breast ultrasound
, a minimally invasive way to screen for breast cancer. Having dense breasts means your breast tissue has more glandular and fibrous tissue than fatty tissue, which can make it harder to see abnormalities on a mammogram. Breast density is just one part of your overall breast health and does not mean you have breast cancer.
Diagnostic mammograms will be read and interpreted the same day
— results are typically available as the radiologist looks at the images while the patient is in the breast center.

Mammogram Information & Awareness
We know that the sheer volume of mammogram (and breast cancer) information out there can be overwhelming, so we have streamlined it below to make it easier for you to find what you need to know.
When to Get a Mammogram
Houston Methodist breast care experts recommend women with an average risk of
breast cancer
should start having annual
screening mammograms
at age 40. If you have a
higher risk for cancer
(such as family history, increasing age, certain genetic mutations linked to breast cancer, like BRCA1 and BRCA 2, being overweight, a sedentary lifestyle or a poor diet), your doctor may recommend you start screening as young as age 30.
You should have a
diagnostic mammogram
if you get called back for more imaging after your screening mammogram, notice any changes at all in your breasts or show
symptoms of breast cancer
. Early signs of breast cancer include a lump in the breast, bloody discharge from the nipple, new pain in one spot that does not go away, and changes in the shape or texture of the nipple or breast.
What to Expect During Your Mammogram
The mammogram process is relatively quick and easy. Your technologist will walk you through each step during your appointment, but here is what you can expect when you get a mammogram at a Houston Methodist Breast Care Center:
First, you will remove your top and bra and put on the provided robe.
Then, a mammogram technologist will help position one of your breasts on the specialized X-ray machine.
Next, the machine will compress your breast for just a few seconds while the technologist takes an X-ray. This process is then repeated about two or three times for each breast. Each compression is very quick, and the entire imaging process lasts about five minutes.
Finally, you will get dressed and continue on with your day.
On the day of your exam, make sure to wear comfortable clothes — you will only need to remove your bra and top. And don’t use deodorant, antiperspirant, powders, lotions, creams or perfumes under your arms or on or under your breast — they can interfere with your test results.

How to Interpret Your Mammogram Results
Radiologists use a standard system to describe mammogram findings and results — and this scoring system is the same for both screening and diagnostic mammography. This system (called the
Breast Imaging Reporting and Data System
or
BI-RADS
) sorts the results into categories numbered 0 through 6.
With these categories, doctors can describe what they find on a mammogram using the same words and terms, making communicating about the test results and following up after the tests easier.
BI-RADS 0-2
: At Houston Methodist, if our radiologists see something on a screening mammogram and want patients to come in for additional images, they are given a BI-RADS 0. This means they will come in for a diagnostic mammogram to evaluate the area of concern. For "normal" mammograms that don't show any abnormal or questionable findings, a BI-RADS 1 or BI-RADS 2 is given.
BI-RADS 3
: A BI-RADS 3 means the radiologist would like to follow something — it is called a “probably benign” category and means that the finding has a 98% likelihood of being benign.
BI-RADS 4-6
: A BI-RADS 4 means the findings are indeterminate and a biopsy is recommended. BI-RADS 5 means it is almost definitely cancer and needs a biopsy, while BI-RADS 6 is only used for findings on a mammogram (or ultrasound or MRI) that have already been shown to be cancer by a previous biopsy. Imaging may be used in this way to see how well the cancer is responding to treatment.
Additional Breast Screenings & Services
There are other breast screenings that typically occur in conjunction with mammograms. These include:
Breast ultrasound
– uses sound waves and their echoes to make computer pictures of the inside of the breast. A breast ultrasound can show certain breast changes, like fluid-filled cysts, that can be more difficult to see on mammograms. Read our On Health blog article
How Is a Breast Ultrasound Different From a Mammogram?
Breast magnetic resonance imaging (MRI)
– an extremely sensitive test to look for breast cancer indicators using magnetic fields to view the body. It also may be used for breast cancer treatment planning and performing an MRI biopsy
Molecular breast imaging (MBI)
– a technique used to identify tumors in dense breasts.

Frequently Asked Questions About Mammograms
Breast sensitivity is very individualized, and whether a woman finds a mammogram to be uncomfortable varies based not only on her pain tolerance but also how her body changes from year to year.
If you’re nervous about the potential for discomfort, the most important thing you can do is communicate the concern with your mammogram technologist. Compression is a critical part of getting the clearest image possible and can’t be avoided, but your technologist will be sensitive to your needs and comfort level.
The benefit of an annual screening mammogram far outweighs any associated risks — including the small amount of radiation exposure during imaging. In fact, the newer mammogram machines used today expose women to only very low levels of radiation, comparable to the background amounts experienced while flying on an airplane.
Women with
breast implants
may also worry about the risk of implant rupture, but this is extremely rare — especially for newer types of breast implants.
screening mammogram
is performed when a woman is due for her annual breast cancer screening. Like other wellness check-ups, this test isn’t meant to answer a specific clinical or diagnostic question. Rather, its purpose is to periodically check the status of the breasts to ensure they’re healthy.
diagnostic mammogram
is performed when a woman is experiencing
breast cancer symptoms
or after receiving an abnormal screening mammogram result. This is still an imaging study, but additional views of the breast are typically taken during a diagnostic mammogram, and the radiologist often reads the images in real time. Additionally, a targeted breast ultrasound may be performed to more closely visualize the area of concern.

Screening Versus Diagnostic Mammograms: What You Can Expect
Women who are asymptomatic and have an
average risk of breast cancer
should begin mammograms at the age of 40 and continue being screened every single year up until good health, which is a personal decision for each woman.
diagnostic mammogram
may be needed before the age of 40 or before a woman’s next screening mammogram if she is experiencing symptoms of breast cancer.
Additionally, having a
higher risk of breast cancer
warrants earlier screening, before the age of 40. Depending on the level of risk, an individualized plan regarding the type and frequency of breast cancer screening will be recommended.
A screening mammogram takes approximately 15 minutes.
This time accounts for you to undress, be positioned for imaging, have your images taken and get dressed again.
Your mammogram technologist is there to help and will be patient with you — so your appointment may take longer than 15 minutes, depending on your comfort level.

Having
dense breasts
means that your breast tissue contains more glandular and fibrous tissue compared to fatty tissue. This is a common and normal condition that many women have. Dense breast tissue can make it a bit more challenging to detect abnormalities on a mammogram because both dense tissue and potential issues appear white on the images. It’s important to remember that breast density is just one factor in your overall breast health, and having dense breasts does not mean you have breast cancer.
At Houston Methodist, we’re here to support you with personalized care, helping you understand your unique breast health and guiding you through the best screening options for you. Your peace of mind and health are our top priorities.
