You’ve probably seen the viral headlines. Every few years, a photo or a "leaked" video surfaces claiming to show a female with 3 boobs, usually accompanied by a story about expensive plastic surgery or a quest for fame. Most of the time? It’s a hoax. A well-placed prosthetic or a clever bit of Photoshop designed to farm clicks from the curious. But if we strip away the tabloid drama and the fake Jasmine Tridevil stories from years ago, there is a very real, very documented medical reality beneath the noise. It’s called polymastia.
It isn't a third breast in the way Hollywood depicts it. You won't usually see a perfectly symmetrical, full-sized mound sitting right in the middle of someone's chest like a scene out of Total Recall. Nature is messier than that.
What Actually Happens in Real Polymastia Cases?
During the early stages of human development—we're talking weeks into being an embryo—everyone develops "milk lines." These lines run from the armpits down to the groin. Usually, these lines disappear except for the two spots that eventually become breasts. Sometimes, the tissue doesn't regress. It stays.
This results in accessory breast tissue. It’s way more common than people think. Estimates suggest that up to 6% of the population has some form of supernumerary (extra) breast tissue or nipples.
Kinda wild, right?
Most of the time, it looks like a small mole or a "third nipple" (polythelia). But in true polymastia, the body develops actual mammary glandular tissue.
Where does it show up?
It’s rarely on the sternum. Most commonly, it’s in the axilla—the armpit. A woman might spend years thinking she just has a stubborn bit of "armpit fat" that won't go away with exercise. Then, during pregnancy or puberty, that "fat" starts to swell, ache, or even produce milk. That’s because it is biologically a breast. It responds to the same hormones as the primary ones.
The Difference Between Fake Viral Stories and Real Medicine
We have to talk about the 2014 Jasmine Tridevil hoax because it’s the reason most people search for a female with 3 boobs today. She claimed to have spent $20,000 on a third breast implant. It was a massive internet sensation. People were obsessed.
But doctors were skeptical from day one. Why? Because finding a surgeon to perform a "tri-masty" is nearly impossible. Ethics boards would have a field day with that. Eventually, it came out that it was a strap-on prosthetic. The "third breast" didn't have a nipple-areola complex that looked remotely biological, and the skin tension required to hold an implant in the center of the chest would be a surgical nightmare.
Real medical cases are documented in journals like the Journal of Clinical Medicine or Case Reports in Obstetrics and Gynecology. These reports don't describe fame-seekers. They describe patients like a 28-year-old woman who went to her doctor because of painful swelling in her axilla after giving birth.
Doctors look for three things to classify this:
- Presence of glandular tissue (the stuff that makes milk).
- Presence of a nipple.
- Presence of an areola.
If you have all three, it’s a full accessory breast. If you just have the nipple, it’s polythelia. If you just have the tissue, it’s just accessory breast tissue.
Why This Matters for Women's Health
Having extra breast tissue isn't just a physical quirk or a "freak show" curiosity. It carries real health implications.
Honestly, the biggest risk is that this tissue is susceptible to the same diseases as normal breasts. That means mastitis, cysts, and yes, even breast cancer. Because the tissue is often in the armpit or hidden under the "normal" breast, it often gets overlooked during routine exams or mammograms.

If a female with 3 boobs (biologically speaking) develops a lump in that extra tissue, she might dismiss it as a swollen lymph node. This can lead to delayed diagnoses.
Dealing with the Physical and Emotional Toll
It’s not just about the "weirdness" factor. Having a third breast, especially one that fluctuates with your period, is uncomfortable.
- Physical discomfort: The tissue can chafe against clothing or the arm.
- Hormonal pain: It gets tender just like regular breasts do.
- Psychological stress: Living in a world that treats your body like a sci-fi trope is exhausting.
Most women who have significant accessory breast tissue opt for surgical removal. It’s usually a combination of liposuction and excision. It’s not about being "normal"—it’s about preventing future health complications and stopping the physical discomfort of carrying extra glandular tissue where it doesn't belong.
Breaking the Stigma of the "Third Breast"
We need to stop treating this like a circus act. When we talk about a female with 3 boobs, we are talking about a variation in human anatomy that has existed since the beginning of time.
In some cultures, throughout history, extra nipples or breasts were even seen as a sign of fertility. It’s only in our modern, hyper-curated visual culture that we’ve decided it’s "creepy" or "fake."
The medical reality is that the human body is incredibly diverse. The "milk line" is a relic of our evolutionary past. Humans are mammals, and while we usually only have two offspring at most (meaning we only need two "stations"), our genetic blueprint still carries the instructions for multiple sites.

What to Do If You Suspect You Have Accessory Tissue
If you’ve noticed a lump in your armpit or along the line down to your groin that seems to change throughout your cycle, don't panic. But don't ignore it either.
Step 1: Get a Professional Opinion
See an OB-GYN or a general surgeon. They can perform an ultrasound or a biopsy to confirm if it’s mammary tissue or just a lipoma (a fatty lump).
Step 2: Check It Regularly
If you choose not to have it removed, you must include that area in your monthly breast self-exams. Feel for changes, hardening, or discharge.
Step 3: Consider Your Options
Removal is a common and relatively straightforward procedure. If the tissue causes you pain or significant anxiety, insurance often covers the excision if it’s causing documented physical discomfort.
Step 4: Stop Following the Hoaxes
The "three-breasted woman" in the movies or on clickbait sites is almost always a lie. The real version of this condition is a medical reality that millions of women manage quietly every day. Understanding the biology helps take the power away from the "freak show" narrative.
Real health is about knowing your own "normal," even if your normal includes a little extra tissue where you didn't expect it. Stay informed, check your body, and ignore the tabloids.
Next Steps for Monitoring Accessory Breast Tissue
- Schedule a clinical breast exam: Specifically ask your provider to check the axillary region (armpits) for accessory tissue.
- Document cyclical changes: Keep a log of whether the area becomes tender or swollen in the days leading up to your period.
- Review your family history: Polymastia and polythelia can have a genetic component; check if other relatives have had "extra nipples" or similar growths.
- Consult a plastic surgeon: If the tissue is causing skin irritation or emotional distress, seek a consultation to discuss the risks and benefits of surgical excision.
