You’ve probably seen the viral headlines. Maybe it was that 2014 story about Jasmine Tridevil—real name Alisha Hessler—who claimed she’d spent thousands on plastic surgery to add a third breast. It turned out to be a hoax involving a prosthetic. People were obsessed. But if you strip away the Florida-man-style internet hoaxes, there is a very real, very biological side to this. It’s called polymastia.
It isn’t a sideshow trick.
For most people, the idea of a girl with three boobs sounds like something out of a sci-fi movie or a Total Recall fever dream. In the medical world, though, it’s a recognized congenital condition where extra breast tissue develops along the "milk line." This line runs from your armpit down to your groin. Most of the time, it’s just a small bump that looks like a mole. Occasionally, it’s a fully formed breast.
The Reality of Accessory Breast Tissue
Let’s get into the weeds here. Human embryos are weird. Around the fifth week of development, we all have these thickened ridges of skin called mammary streaks. Usually, these streaks disappear everywhere except for the two spots that eventually become our breasts. But biology is messy. Sometimes, bits of that tissue stick around. When that happens, you get what doctors call accessory breast tissue or polymastia.
It’s actually more common than you’d think. Research published in the Journal of Clinical and Diagnostic Research suggests that up to 6% of the population has some form of supernumerary (extra) breast tissue. It’s more frequent in some ethnic groups and slightly more common in women than men.
Most people don't even know they have it. They might have a "third nipple"—which is polythelia—and just assume it’s a birthmark or a freckle. It's often only when puberty hits or a woman gets pregnant that things change. Because this extra tissue is hormonal, it can swell, leak milk, or become tender just like regular breast tissue. Imagine being 14 and suddenly growing a lump in your armpit that hurts every month. That’s the reality for many girls dealing with this.

Where Does It Show Up?
It’s rarely right in the middle of the chest like the fake viral photos. That’s almost physically impossible because of how the mammary glands are structured. Instead, you usually see it in the axilla (the armpit). In very rare cases, it can show up on the back, the thigh, or even the vulva. I know, it sounds wild. But because those milk lines are so long in the embryo phase, the tissue can get stranded almost anywhere on the trunk of the body.
Why the Internet is Obsessed With the Hoax
We have to talk about the 2014 incident because it permanently warped how people search for a girl with three boobs. Alisha Hessler claimed she couldn't find a boyfriend and wanted to be a reality star, so she supposedly found a doctor to perform a "forbidden" surgery.
The media ate it up.
Reputable news outlets were scrambling. Then, airport security found a three-breast prosthetic in her luggage. The "surgery" never happened. No ethical surgeon would actually do that. It would be a massive violation of the Hippocratic Oath to perform a disfiguring surgery that serves no physiological purpose and carries high risks of necrosis or infection.
The internet loves a freak show, but the medical reality is much more mundane and, honestly, a bit of a hassle for those who actually have the condition.

The Physical and Emotional Toll
If you actually have polymastia, it’s not a ticket to fame. It’s a medical concern.
- Physical discomfort: Extra tissue in the armpit can limit range of motion.
- Hormonal fluctuations: The tissue responds to the menstrual cycle.
- Cancer risks: This is the big one. Because it’s real breast tissue, it can develop the same pathologies as normal breasts, including fibroadenomas or even breast cancer.
Diagnostic imaging like ultrasounds or mammograms is way harder when the tissue is in an unusual spot. Radiologists often miss it because they aren't looking for a tumor in a patient's armpit or side. This is why awareness matters. It’s not just about "looking weird"—it's about staying healthy.
Treatment: Is Surgery Necessary?
Most doctors take a "wait and see" approach. If the extra breast isn't causing pain and isn't a cosmetic concern for the patient, they usually leave it alone. But "leaving it alone" means you have to include that area in your monthly self-exams.
If it is causing issues, the solution is usually a surgical excision. It’s not a simple "snip and stitch" job. Surgeons have to ensure they remove all the glandular tissue to prevent it from growing back or causing future cysts. Sometimes they use liposuction if it's mostly fatty tissue, but for true polymastia, you need a scalpel.
It's expensive. Most insurance companies label this as "cosmetic" unless you can prove it's causing significant physical pain or interfering with your life. That's a huge hurdle for a lot of women.

Navigating the Social Stigma
Let's be real—growing up as a girl with three boobs (or even just an extra nipple) is a nightmare for a teenager. We live in a world that is hyper-fixated on breast symmetry and "perfection."
I’ve read accounts from women who felt they had to hide their bodies for years. They wouldn't wear tank tops. They avoided swimming. They felt like "freaks" because of a minor biological glitch. When the media turns the condition into a joke or a hoax, it makes it even harder for real people to seek help or talk about their experiences without feeling like a punchline.
Real Expert Insights
Dr. Susan Love’s Breast Book is basically the bible for this stuff. She notes that while supernumerary tissue is a variation of normal, it requires the same vigilance we give to our primary breasts. The medical community is shifting toward being more supportive of early excision for psychological reasons, acknowledging that the mental health impact of "feeling different" is a valid reason for surgery.
There's also a genetic component. If your mom or grandma had an extra nipple or accessory tissue, there’s a higher chance you will too. It’s just one of those quirks of heredity, like having a hitchhiker’s thumb or being able to roll your tongue.
Actionable Steps for Management
If you suspect you have accessory breast tissue, don't panic. It's usually benign. Here is how you should actually handle it:
- Consult a Specialist: Don't just go to a general practitioner. See a breast specialist or a dermatologist who understands "milk line" anomalies.
- Get an Ultrasound: If you have a lump that changes size during your period, get it imaged. You need to know if it's just fat, a lymph node, or glandular breast tissue.
- Monitor Hormonal Changes: Keep a diary. Does the area swell when you're on your period? Does it hurt? This info is gold for your doctor.
- Check Your Insurance: if you want it removed, start documenting "pain" or "restriction of movement" early. Insurance is much more likely to cover the procedure if it’s coded as a functional issue rather than a cosmetic one.
- Ignore the Tabloids: Real polymastia doesn't look like a movie prop. It’s a part of your body that just happened to grow in a different spot.
Biology doesn't always follow the blueprint perfectly. Whether it's a tiny extra nipple or a more developed accessory breast, it's a common human variation that deserves medical attention and personal acceptance, not internet sensationalism. Understanding the "why" behind the tissue makes it a lot less scary and a lot more manageable. Only by looking at the actual science can we move past the hoaxes and treat the condition with the seriousness it requires.
