Breast cancer in men is real. It accounts for about 1% of all breast cancer cases in the United States, which works out to roughly 2,670 new diagnoses and 530 deaths per year according to the American Cancer Society. Globally, cases more than doubled between 1990 and 2021 — a 272% increase — based on data published in Clinical Breast Cancer using the Global Burden of Disease database across 204 countries.
That is a drop in the ocean compared to the 1 in 8 at risk women. When the diagnosis hits you or your own family, however, and you find yourself sitting in a doctor’s office, hearing the phrase breast cancer, but with a man in the sentence, your numbers are no longer abstract. The mean age at which it has been diagnosed ranges between 60 and 70 and lifetime risk of men is approximately 1 in 755 as indicated by the American Cancer Society.
It is not that male breast cancer is an issue in itself. The issue is that nearly all about the way we discuss it, search it, and handle it is constructed on the premise that it does not.
Misconceptions That Delay Diagnosis and Cost Lives
The majority of the risk surrounding male breast cancer is not due to the fact that the illness is inherently agile. Men and women actually fare equally, stage by stage. The risk is that men will be diagnosed later, with the problem of diagnosis being caused by a misconception about the issue that is so widespread that most people now accept the information without doubting it.
#1 — “Men Don’t Get Breast Cancer”
They do. Men have breast tissue — not as much as women, but enough for cancer to develop in. The most common type is invasive ductal carcinoma, which starts in the milk ducts and accounts for roughly 90% of all male breast cancer cases according to the National Cancer Institute and StatPearls (NCBI Bookshelf). Men can also develop ductal carcinoma in situ, and in rare cases, inflammatory breast cancer or Paget disease of the breast.
The reason men have breast tissue at all is straightforward biology. Before puberty, breast tissue in boys and girls is virtually identical. During puberty, hormones cause female breast tissue to develop further while male breast tissue mostly stays dormant. But “mostly dormant” isn’t the same as “gone.” The ducts are still there. And ducts are where most breast cancers begin.
#2 — “It Only Happens If It Runs in the Family”
This one gets people killed because it gives men without a family history of breast cancer a false sense of security.
According to the American Cancer Society, the majority of men with breast cancer do not have any known risk factors except age. The National Cancer Institute agrees. Yes, having a first-, or second-,degree relative with breast cancer is a risk factor. The BRCA2 gene mutations are indeed associated with a high risk of male breast cancer. However, most of the cases present themselves in men who had no specific cause to anticipate it.
In a PMC study on 19,795 male breast cancer patients in the National Cancer Database (2004-2014), the majority of the cases were among men who self-identified as non-Hispanic white, with a mean age of 64.6 years, and had no prior sign that breast cancer was imminent. Delaying to seek medical attention until the disease has spread to other family members is playing with time that you may not have.
#3 — “A Lump in the Chest Is Probably Nothing Serious”
Men commonly present with a painless lump under or near the nipple. Because breast cancer isn’t on their radar, they rationalize it as a gym injury, a cyst, fatty tissue, or just something that’ll go away on its own.
The same pattern was observed by a survivor of breast cancer Michael Singer of the Bronx, who has been interviewed by the CBS News. When he had a routine physical he noticed that there was a pencil-shaped lump under his left nipple but he did not inform the doctor. His follow-up appointment was the only time he eventually brought it up. Surgical biopsy was done and he was found to have breast cancer a few days later. The response first was disbelief: he believed that his doctor had mixed his chart with that of his sister who had died of metastatic breast cancer two years before.
It is the delay that also exposes men to a higher likelihood of having the cancer diagnosed at an advanced stage. A National Cancer Database analysis published by PMC compared the male and female breast cancer patients in 13 years (2004-2016) and discovered that men had an earlier clinical staging, adverse disease grades, and a higher prevalence of cancer that had already metastasized to the nearby lymph nodes at the time of diagnosis.
#4 — “Screening Would Catch It If It Were Real”
There are no routine screening mammogram programs for men. None. The NCI notes that screening mammograms are not usually recommended for men, even those at increased risk. The American Cancer Society advises men with known risk factors to discuss monitoring options with their doctor, but there’s no standardized protocol the way there is for women.
This means detection in men depends almost entirely on the man himself noticing a change and deciding to act on it — which circles right back to all the misconceptions above. If a man doesn’t believe he can get breast cancer, he’s not going to interpret a breast lump as something that needs medical attention. And without a screening system to catch it independently, the cancer just grows.
#5 — “Treatment Probably Doesn’t Work As Well for Men”
The results are similar stage by stage. In a massive SEER (Surveillance, Epidemiology, and End Results) study by the National Institutes of Health, the survival curve of male breast cancer closely matched that of female breast cancer, after adjusting for diagnosis stage.
The total relative 5-year survival rate is a bit lower in men 82.8 versus 88.5 depending on the available data considered in various PMC studies. Much of that gap however is due to the simple fact that men are diagnosed later than not because the disease does not react the same way to treatment. Treatment is effective when the stage is identical.
Breast cancer in men is also almost exclusively hormone receptor-positive – about 90% of them have estrogen receptors based on StatPearls – so hormonal therapy (which is actually a combination of tamoxifen) works in the majority of cases. Tamoxifen has also been reported to lower the chance of recurrence by about 51 percent in male breast cancer just like in the case of women.
The Barriers That Keep Men Silent
Misconceptions are part of the problem, but they aren’t the whole picture. Even men who know something is wrong sometimes avoid seeking help because of barriers that have nothing to do with medical knowledge and everything to do with how society frames this disease.
The Stigma of a “Women’s Disease”
Literature that has been published in PMC has reported that men diagnosed with breast cancer often have a crisis related to their masculinity. There were men who stated that because of the diagnosis they felt like their manhood was taken away or they were less of a man. These are not edge cases or exaggerations, this is a documented psychological trend among the breast cancer patients of the male gender.
Such stigma brings about avoidance behavior. The reason why men put off visiting a doctor is the judgment. They downplay the symptoms since it is disgraceful to be a man and to confess to a breast issue. There are those who do not even say the word breast cancer even when they are diagnosed.
Mathew Knowles Bayonce father was diagnosed with breast cancer, and publicly maintained that the term should not be used, rather using the term male chest cancer, which was considered more palatable to men with the condition who are averse to the association of their body with the word breast. He is a carrier of BRCA2 gene, a fact that he found out only after the mastectomy procedure. In an op-ed after being diagnosed, Knowles urged men to take their health seriously and go through genetic testing as opposed to thinking that the disease could not happen to them.
No Clinical Trials Built for Men
Here’s something that doesn’t get discussed enough: treatment protocols for male breast cancer are almost entirely borrowed from trials conducted on female patients. Specifically, treatment mirrors what’s used for postmenopausal women, because the hormonal profile is considered the closest match.
The PMC epidemiology study on male breast cancer stated it directly — due to low incidence, there is a lack of randomized trials aimed specifically at male breast cancer patients. No large-scale, prospective, male-specific clinical trials have reported results as of the most recent literature. Every treatment decision for a man with breast cancer is being made based on evidence gathered predominantly from women.
That’s not necessarily wrong in every case, but it’s a gap. Men metabolize drugs differently. They have different hormonal environments. The assumption that what works for postmenopausal women will work identically for men is a practical workaround, not a scientific confirmation.
Psychological Support Barely Exists
The same PMC research documented that men with breast cancer experience high levels of psychological distress, including anxiety, depression, fear of recurrence, fatigue, and insomnia. These aren’t side notes in a clinical paper — they’re consistent findings across multiple studies examining quality of life in male breast cancer patients.
But unlike women, who have extensive support networks, survivor communities, awareness campaigns, and dedicated resources, men with breast cancer largely navigate the emotional fallout alone. Support groups are overwhelmingly female-focused. Awareness campaigns feature pink ribbons and messaging directed at women. A man walking into a breast cancer support meeting is walking into a room that wasn’t designed with him in mind, which can reinforce the exact isolation the support is supposed to address.
Men Who Spoke Up — And What Changed Because They Did
Richard Roundtree — The Actor Who Waited Five Years
Richard Roundtree, widely known for his role as the lead in the 1971 film Shaft, was diagnosed with breast cancer in 1993 after finding a lump in his chest. He underwent a mastectomy and was successfully treated, but he didn’t tell anyone publicly for five years.
When he finally did, it was at a celebrity golf tournament raising funds for breast cancer services. In his own words to ABC News in 2007: “I just got up and told everybody that I was a breast cancer survivor. The room was totally silent. I think it dawned on people that men can be affected by this too.”
In a later interview with Extra, Roundtree reflected on the experience more bluntly: “Coming out of the closet about my breast cancer episode, that was an eye-opener for me because I really got to experience the fact that men are so cavalier about their health issues and want to sweep it under the rug.”
Roundtree passed away from pancreatic cancer in October 2023 at age 81. His willingness to eventually speak publicly about his breast cancer diagnosis remains one of the most cited examples in male breast cancer awareness.
Peter Criss — The Drummer Who Called It a Nightmare
Peter Criss, the original drummer for KISS, found a lump in his chest after a workout in 2007. Doctors initially thought it was a harmless nodule, but testing confirmed it was cancerous. Surgery removed the cancerous tissue, and because it hadn’t spread, no additional treatment was needed.
Criss shared his experience on CNN in 2009 and has been vocal about male breast cancer awareness since. His message has been consistent and direct: “Don’t sit around playing Mr. Tough Guy. Don’t say ‘It’s going to go away.'”
His case is a useful example of what happens when a lump gets checked instead of ignored. Because he acted on it — even though it initially looked benign — the cancer was caught before it could spread, and treatment was straightforward. That’s the entire argument for early detection compressed into one real outcome.
Michael Singer — From “Chest Cancer” to Advocate
Michael Singer’s story, covered by CBS News, captures the stigma barrier more vividly than almost any statistic could.
When Singer was diagnosed with breast cancer while nearing retirement, his coworkers and friends knew he had cancer, but didn’t know what kind. He purposely told people that he had “chest cancer” for months because he was scared of the stigma attached to a man having breast cancer. In his own words: “I was afraid there would be some sort of stigma attached to me having male breast cancer.”
The turning point arose more than a year later. A friend called and said for him to turn on the television. Richard Roundtree and Brett Miller, founder of a male breast cancer awareness non-profit organization called 1T Foundation, were on a daytime talk show talking about the disease. It was an epiphany for me, says Singer: “I can’t sit back. I can’t be quiet. The embarrassment is over. I’m going to go out there and I’m going to talk about this.”
Since then, Singer has volunteered with the Congressionally Directed Medical Research Program sharing firsthand experience with researchers, completed Project Lead (an intensive science program for breast cancer advocates), spoken at American Cancer Society events, worked with the Breast Cancer Research Foundation, and spent his own money making pink and blue bracelets and lapel pins that he hands out on the streets of the Bronx and New York City.
“I want to be the voice for the guys who aren’t here anymore,” Singer told CBS News. “And I want to be the voice for guys who are here to let them know there’s such a thing as male breast cancer.”
What Men Should Actually Watch For
Male breast cancer symptoms are often easier to detect physically than in women because there’s less breast tissue to obscure a lump. But that advantage only matters if the man is paying attention and knows what to look for.
Signs that need medical attention:
- A painless lump or thickening in the breast or chest area, usually near or under the nipple
- Changes to the nipple — retraction (pulling inward), discharge, or scaling
- Dimpling, puckering, or redness of the skin over the breast
- A lump or swelling in the underarm lymph nodes
The NCI and American Cancer Society both emphasize that most breast changes in men turn out to be benign conditions like gynecomastia (breast tissue enlargement from hormonal imbalance). But benign and malignant can look similar from the outside, and the only way to know the difference is getting it checked.
Speaking of gynecomastia — it’s actually worth knowing that this condition can mask breast cancer. Enlarged breast tissue can make a new lump harder to notice, and men who already have gynecomastia may assume any breast changes are just more of the same. The Susan G. Komen Foundation flags this specifically as a complicating factor in male breast cancer detection.
Risk Factors Backed by Research
Most men who develop breast cancer have no identifiable risk factor beyond age. But several factors are known to increase risk, and being aware of them can inform conversations with a doctor.
- Age — median diagnosis age is 69 according to Susan G. Komen data covering 2018-2022 US cases
- BRCA2 gene mutations — the most significant genetic risk factor for male breast cancer. BRCA1 mutations carry some increased risk but the link is weaker
- Family history — a first-degree relative (parent, sibling, child) with breast cancer increases risk for both men and women
- Klinefelter syndrome — a rare genetic condition where males have an extra X chromosome, associated with a 20 to 50-fold increase in breast cancer risk per Wikipedia’s medical sources
- Radiation exposure to the chest — particularly from previous cancer treatment
- Liver disease — chronic conditions like cirrhosis can raise estrogen levels in men
- Obesity — increases estrogen production through fat tissue
- Testicular conditions — orchitis (inflammation), undescended testicle, or surgical removal of one or both testicles can alter hormone balance
A study published in Clinical Breast Cancer analyzing the Global Burden of Disease data found that among men diagnosed with breast cancer, high red meat consumption was the top modifiable factor linked to breast cancer death, followed by alcohol consumption and secondhand smoke exposure.
Where Things Stand — And What Still Needs to Change
Male breast cancer research is beginning to pick up, but the gaps are still significant. No prospective clinical trials conducted exclusively in male breast cancer patients have reported results. Treatment continues to resemble postmenopausal female treatment. Screening programs for men don’t exist. Psychological support infrastructure is limited. Awareness campaigns still overwhelmingly focus on women, even though the messaging could save men’s lives with very minor tweaks.
The cost of treatment isn’t insignificant either. A PMC review put the average cost for treatment of male breast cancer in the United States at $50,000 to $100,000 or even $200,000 for advanced stage cases. Late diagnosis doesn’t just mean a difference in survival odds – it means a difference in the financial burden on patients and their families.
What actually needs to happen is easy enough even if the execution is slow. Men need to know they can get breast cancer. Doctors need to think about it as a differential diagnosis when a man comes in with a breast lump instead of thinking that it must be gynecomastia. Researchers need funds for trials specific to males. Support systems need to be inclusive enough that a man walking through the door does not feel as if he’s in the wrong room.
Richard Roundtree put it in the simplest terms that he could when going public. The room went silent as people really didn’t know that men could get breast cancer. That silence – that gap in basic awareness – is the barrier on which everything else is based.
