Getting your annual mammogram is one of the best ways to take charge of your health, and we know you want answers quickly. The good news is that we’re here to guide you and explain what to expect so that you can feel confident in your care.
Keep reading to learn more about how long mammogram results take, why a screening exam is slower than a diagnostic one, how to read the report when it arrives, what a callback means and when to follow up if you haven't heard anything.
The Typical Timeline
For a routine screening mammogram, you can expect results within a few weeks. Our imaging centers aim for a shorter turnaround than that, and we do our best to post to your patient portal within days.
The reason it isn't instant is that one of our radiologists reads your images after your appointment rather than during it, and often compares them against your previous mammograms before signing off. Under federal rules, you receive a written summary in plain language, along with a statement about your breast density.
Why a Diagnostic Mammogram Is Usually Faster Than a Screening One
Whether you’re having a diagnostic mammogram for specific symptoms or a callback from a screening, the timeline for results is often much shorter. Part of the reason is that a radiologist frequently reviews your images while you’re still at the imaging center, so you may get preliminary information before leaving, rather than waiting for a letter in the mail. A little preparation also makes the exam smoother, including not wearing deodorant to your mammogram.
What Can Make a Diagnostic Mammogram Longer
Several factors may delay the timeline for receiving your diagnostic mammogram results. One of them is if your previous mammograms were done at a different facility. This may require the radiologist to wait longer for those images to compare. Holiday and weekend hours also push reports to the following week. And if the first read of your result raises concerns, your results may be held while your radiologist consults a colleague to review the findings. But it’s important to remember that none of these reasons mean something is wrong — it means your care team is going the extra mile to ensure accurate results.
Mammogram Results: Why Two Weeks Is So Common
While waiting two weeks for your mammogram results may feel long, it reflects how the process is structured. After your appointment, your images enter a reading queue, where they’ll be compared with prior imaging. Once the results are interpreted and dictated, you’ll receive a letter with your results. Each step is short, but when combined, they usually add up to a couple of weeks in most cases.
Reading Your Report When It Arrives
Mammogram reports use a standardized scoring system called BI-RADS, which assigns a category summarizing what was seen and the recommended next steps. Categories range from normal results to findings that call for additional imaging or a biopsy. However, a category recommending additional imaging is common and isn’t a diagnosis.
Your report also names your breast density category. Dense tissue and possible tumors both appear white on a mammogram, so density affects how your images are read and may give you and your doctor a chance to talk through supplemental imaging.
What If You Get a Callback?
Being asked to return for further imaging isn’t cause for alarm, and it’s actually more common than most people realize. Fewer than 1 in 10 women called back for additional testing were found to have cancer. Callbacks are especially common after your first mammogram because there are no prior images to compare with. If you receive a callback, schedule your follow-up promptly and bring any prior imaging you have.
When to Follow Up
If several weeks have passed and you've received nothing, call your clinician’s office or the imaging center and ask directly. Reports can be delayed, and portal notifications can be missed.
Contact your doctor sooner, without waiting for the report, if you notice a new lump or thickening, a change in breast size or shape, skin dimpling, nipple changes or discharge. These warrant evaluation on their own timeline.
