Can Men Get Mammograms? Why and What to Expect

Men can absolutely get mammograms, and thousands do every year. The procedure is not reserved for women, even though nearly all public messaging around breast imaging targets a female audience. In men, mammograms are almost always diagnostic rather than routine screening, ordered when a doctor finds something worth investigating. That distinction, along with the social awkwardness many men feel walking into a breast imaging center, shapes almost every part of the experience.

Why a Man Would Need a Mammogram

The most common reason a man ends up in a mammography suite is a change he or his doctor has noticed in the chest area. In a study of 263 men who underwent mammography, the two leading reasons were breast tenderness (about a third of cases) and a palpable lump (about 30%).¹ Other triggers include nipple discharge, nipple retraction, skin changes like dimpling or thickening, or swelling that seems to affect one side more than the other. A lump that is hard, fixed in place, off-center from the nipple, or accompanied by enlarged lymph nodes under the arm raises particular concern and warrants prompt imaging.²

Unlike women, who are encouraged to start routine screening mammograms at a certain age, men do not have standard screening recommendations. The prevalence of male breast cancer is simply too low to justify population-wide screening. Mammography in men is a diagnostic tool, meaning it is ordered in response to a specific symptom or clinical finding rather than as a periodic check-up.³ That said, there is a narrow group of high-risk men for whom periodic imaging may be discussed, which is covered further below.

Gynecomastia Is the Most Common Finding

If you are a man being sent for a mammogram, the odds are strongly in favor of a benign result. The vast majority of male breast concerns turn out to be gynecomastia, an enlargement of the glandular breast tissue that can affect one or both sides.⁴ Gynecomastia has characteristic imaging features that allow radiologists to distinguish it from cancer on a mammogram without much ambiguity.⁵ It tends to fan out symmetrically behind the nipple, whereas cancer typically appears as an irregular, off-center mass.

Another common benign finding is pseudogynecomastia, which is not glandular tissue at all but simply fat accumulation under the nipple area. On a mammogram, it looks distinctly different from true gynecomastia because there is no glandular component, just fatty tissue.⁶ Lipomas and other harmless lumps can also show up. The point is that most men who undergo breast imaging leave with reassurance, not a cancer diagnosis.

What the Procedure Actually Feels Like

The mechanics of a male mammogram are the same as a female one. Your breast tissue is positioned on a flat plate and compressed by a second plate from above or from the side, and an X-ray image is captured. The compression is necessary to spread the tissue thin enough for the X-ray to pick up subtle abnormalities. Two standard views are typically taken of each breast.

For men, the physical experience can feel more awkward than painful. Male breast tissue is usually smaller, which means the technologist has to work harder to get enough tissue positioned between the plates. There is less to compress, and the chest wall is often flatter, so the sensation tends to be brief and uncomfortable rather than the sustained squeeze that many women describe. That said, if you have gynecomastia or significant tissue, the compression can be genuinely uncomfortable for those few seconds. A bilateral mammogram, covering both sides, is generally preferred over imaging only the symptomatic side because comparing the two helps the radiologist spot asymmetries and can catch problems on the opposite side.³

The appointment is short. Expect the imaging itself to take around 15 to 20 minutes, though you may spend more time in the waiting room and changing into a gown than you do in front of the machine. You will likely be in a facility that primarily serves women, and you may be the only man in the waiting area. That is completely normal and something the staff encounters regularly.

How Accurate Is a Mammogram in Men

Mammography performs well in men. The sensitivity for detecting male breast cancer is roughly 92 to 95%, and the specificity is in the same range.³ In practical terms, sensitivity means the mammogram catches the vast majority of cancers that are there, and specificity means it correctly identifies most non-cancerous findings as benign. One study found mammography was the most sensitive method for detecting malignancy at about 95%, while ultrasound was the most specific at about 95%.⁷

There is some variation in published accuracy figures. A separate study proposed that ultrasound alone could serve as the first-line imaging tool for men, reporting ultrasound sensitivity of 100% and specificity of 97%, compared with mammography sensitivity of 69% and specificity of 87% in that particular patient group.⁸ The discrepancy likely reflects differences in study populations and methods, but it highlights that ultrasound is not just a backup. It is a genuinely useful complement. When a mammogram is abnormal or inconclusive, ultrasound is typically the next step. For men under 25, guidelines suggest starting with ultrasound and adding a mammogram if needed.³ Ultrasound can also help characterize the stage of gynecomastia, distinguishing early-phase tissue changes from later fibrotic ones.⁹

MRI of the male breast exists as well, though it is far less commonly used. It is primarily considered when evaluating the extent of a known cancer before or after surgery, or during follow-up. MRI is seen as a complement to mammography and ultrasound rather than a replacement.¹⁰

What Happens If Something Suspicious Shows Up

If the mammogram or ultrasound reveals a finding that the radiologist cannot confidently call benign, the next step is usually a core needle biopsy. This involves using a hollow needle, often guided by ultrasound, to extract small samples of tissue for examination under a microscope. It sounds more dramatic than it is: the area is numbed with local anesthesia, and the procedure itself takes only a few minutes.

Core needle biopsy is highly reliable in the male breast. In a series of 234 male breast lesions evaluated with ultrasound-guided biopsy, sensitivity for detecting cancer was about 99%, and overall accuracy reached nearly 100%.¹¹ Roughly 59% of those biopsied lesions turned out to be benign, which again underscores that a biopsy recommendation does not mean you have cancer. It means the imaging was not definitive enough on its own. Biopsy helps surgeons plan ahead: if the lesion is cancerous, they already know what they are dealing with before operating, and if it is benign, unnecessary surgery is avoided.¹² A second large single-center series confirmed that core needle biopsy should be a routine part of the workup for a one-sided male breast lump.¹³

Male Breast Cancer Is Rare but Real

Men account for less than 1% of all breast cancer diagnoses.¹⁴ In the United States, that translates to roughly 2,800 new cases per year, compared to about 300,000 in women. The rarity itself is part of the problem. Because breast cancer in men is so uncommon, men are less likely to recognize a lump as something worth getting checked, and even some primary care providers can initially dismiss the symptom.

When male breast cancer does occur, it tends to show up later in life than in women, often presents at a higher stage, and is more frequently hormone receptor–positive.¹⁴ On imaging, it characteristically appears as an irregular mass located just behind or slightly off-center from the nipple. Nipple retraction, skin thickening, and tiny calcifications may also be visible.¹⁵ Population-level data show that while survival rates for male breast cancer have improved over the decades, the gains have not kept pace with the improvements seen in women. Comparing more recent patients to those diagnosed a generation earlier, death rates from breast cancer dropped by about 28% in men but about 42% in women.¹⁴ Even after accounting for stage and grade, early-stage male breast cancer tends to carry worse survival than the equivalent stage in women.¹⁶

Who Is at Elevated Risk

Most men who develop breast cancer have no obvious family history or genetic mutation. But two groups stand out as having meaningfully higher risk. The first is men who carry certain gene mutations, particularly in the BRCA2 gene. In families with a strong breast cancer history, BRCA2 mutations may be responsible for 60 to 70% of male breast cancer cases. The cumulative lifetime risk of breast cancer for a BRCA2 carrier is roughly 7 to 8% by age 80, which is far higher than the general male population but still much lower than the risk BRCA2 poses to women.¹⁷ BRCA1 mutations also raise male breast cancer risk, but less so, with a cumulative risk of about 1.2% by age 70. Beyond the BRCA genes, mutations in CHEK2 and PALB2 have also been linked to increased risk in multi-gene panel testing.¹⁸

The second notable high-risk group is men with Klinefelter syndrome, a chromosomal condition. Together with BRCA2 carriers, this group accounts for up to about 15% of male breast cancer cases. Other risk factors include liver disease, obesity, and certain occupational exposures, though none of these individually identify a group with large numbers of cases.¹⁹ Genetic testing is now commonly recommended for any man diagnosed with breast cancer, regardless of his age or family history.¹⁷

Screening for High-Risk Men

Given those risk factors, you might expect clear screening guidelines for men with BRCA2 mutations or Klinefelter syndrome. In reality, formal recommendations are sparse. Due to the low overall prevalence of male breast cancer and limited supporting data, there are currently no widely endorsed image-based screening programs for men, even those at high risk.²⁰ Some expert guidelines suggest that BRCA2 carriers should perform breast self-exams and discuss periodic clinical breast exams with their doctor starting around age 35, with mammography considered on an individual basis. But this falls short of the structured screening programs available to women, and the evidence base behind it is thin.

The challenge is a numbers problem. Even among BRCA2 carriers, the absolute risk is in the single digits over a lifetime. Screening with mammography works best when the disease you are looking for is common enough to justify the cost and the false positives that inevitably come with any screening program. For now, the practical advice for high-risk men is to stay aware of changes in the chest area and not delay getting symptoms checked.

The Embarrassment Factor

One of the underappreciated barriers to male breast cancer diagnosis is embarrassment. In a study that interviewed men diagnosed with breast cancer, over 90% reported experiencing some degree of embarrassment when they first noticed symptoms. All of those men admitted the embarrassment caused them to hesitate before seeking medical attention. The discomfort did not end at the doctor’s office, either: over 90% reported feeling uneasy in waiting rooms where every other patient was female.²¹

This is not just an emotional inconvenience. Delayed presentation leads to later-stage diagnosis, which directly affects outcomes. Some men in the study reported that even their primary care providers initially dismissed their breast symptoms, adding a professional-level delay to the patient-level one. The cultural framing of breast cancer as exclusively a women’s disease, reinforced by decades of pink-ribbon campaigns, has been effective at raising awareness in women while leaving men largely in the dark.²¹ If you are a man with a breast symptom, it is worth knowing that imaging technologists see male patients regularly and that there is nothing unusual about a man getting a mammogram from the clinical staff’s perspective.

Treatment After Diagnosis

If a mammogram and biopsy do confirm cancer, treatment follows a path that will look familiar to anyone who knows about breast cancer in women. Surgery, radiation, chemotherapy, and endocrine therapy are all on the table, and the choices depend on the cancer’s stage and receptor status. Because male breast cancer is so frequently hormone receptor–positive, endocrine therapy plays a central role. The ASCO guideline for male breast cancer recommends tamoxifen as the standard adjuvant endocrine treatment for an initial five years. Men who tolerate it well and remain at high risk of recurrence may be offered an additional five years. For those who cannot take tamoxifen, alternative hormonal approaches exist.²²

For advanced or metastatic disease, endocrine therapy is typically the first-line treatment unless the cancer is progressing rapidly. Targeted systemic therapies approved for women can also be used in men under the same indications.²² The honest reality is that most treatment protocols for male breast cancer are adapted from research conducted overwhelmingly in women. Male-specific clinical trials have been rare, and much of what guides treatment in men is extrapolated from female data combined with smaller observational studies in male cohorts.

Mammography for Transgender Individuals

The question of whether men can or should get mammograms extends into transgender health in ways that are clinically important. Transgender women (assigned male at birth, now living as women) who take estrogen-based hormone therapy develop breast tissue over time. Current recommendations suggest that transgender women who have been on hormone therapy for five or more years and are over 50 should be offered screening mammograms every two years, following a logic similar to screening guidelines for cisgender women.²³ One practical consideration is that hormone therapy often produces dense breast tissue, which both raises the baseline risk of breast cancer and makes mammograms harder to read because dense tissue can obscure abnormalities.²³

Transgender men (assigned female at birth, now living as men) who have not had chest surgery retain breast tissue and generally follow the same screening guidelines as cisgender women, adjusted for their individual risk factors. Those who have had top surgery still have some residual tissue in most cases, and the approach to imaging after surgery is handled on a case-by-case basis. The screening protocols in this area are still evolving and are not yet firmly evidence-based, but the guiding principle is to match imaging recommendations to the breast tissue present rather than to the person’s gender identity.²⁴

Why AI Has Not Yet Changed Male Breast Imaging

Artificial intelligence tools are increasingly being tested and deployed in breast imaging, and you might wonder whether they help with the relatively rare task of reading a male mammogram. The short answer is that no AI diagnostic imaging models for mammography, MRI, or ultrasound have been clinically validated in male patients. Every published study on breast imaging AI pertains to female cohorts or general populations that are overwhelmingly female. There are no diagnostic accuracy numbers for AI applied specifically to male breast imaging. Until male-specific validation studies are conducted, radiologists reading a male mammogram rely entirely on their own training and standard reporting frameworks rather than algorithmic support. Given how rare male breast imaging is relative to female imaging, building a dataset large enough to train and validate AI for men is a significant logistical hurdle that is unlikely to be resolved soon.
