Montgomery Glands and Bumps on the Areola: Why the Small Raised Dots Are Normal, When a Lump Behind the Nipple Needs an Ultrasound, What Can and Cannot Be Done About Bumps and Areolar Hair, and Which Changes Call for a Biopsy Instead of a Cosmetic Fix

The patient is 31, has never been pregnant, and has a list of three concerns for a breast consultation. The first two are about volume and shape. The third, written at the bottom of the intake form, is the one the patient actually wanted to talk about: "bumps on my nipples, can these be removed?" The bumps in question are a ring of small, skin-colored raised dots scattered across both areolas, a few more on the left than the right. They have been there since adolescence. They got larger for a few months after the patient started a new birth control pill, and they have never gone away entirely.

They are almost certainly Montgomery glands, and they are on nearly every areola. The question of whether to remove them is a reasonable one to ask, but it is a different question from the one most patients think they are asking. They are not asking how to get rid of a blemish. They are asking whether to cut out a normal gland that sits in thin, pigmented skin that scars and changes color unpredictably.

This piece explains what Montgomery glands and tubercles are, why they enlarge with pregnancy, hormones, and sometimes after breast surgery, how the cysts that occasionally form behind them are usually handled, what can be done about prominent bumps and hair on the areola, and which changes on the nipple and areola are not cosmetic problems at all. It builds on the earlier pieces on nipple and areola reduction and galactorrhea and nipple discharge after augmentation, which touched on the areola without covering its glands.

What Montgomery glands are, and why almost everyone has them

The short answer: Montgomery glands are small glands in the areola that combine an oil-producing sebaceous gland with a rudimentary milk-producing unit; they open onto the surface as the raised bumps called Montgomery tubercles, they are present in most people of every sex, and they are a normal part of breast anatomy rather than a skin condition.

The areola is not just pigmented skin. Scattered across it, usually toward the outer half, are glands that anatomists have described since the nineteenth century, named for the Irish obstetrician William Fetherstone Montgomery, who wrote about them in pregnancy. Each is an areolar gland that opens through a small elevation in the skin. Histology studies describe them as a sebaceous gland paired with a small lactiferous (milk) duct, which is why they can produce both an oily secretion and, occasionally, a few drops of milky fluid. The raised surface openings are the tubercles. The terms get used interchangeably in clinic, and in older literature the bumps on a non-pregnant areola are sometimes called tubercles of Morgagni.

The number varies widely. Studies that counted tubercles in women report averages in the range of roughly ten to fifteen per areola, with some people having almost none and others having thirty or more, and with a common difference between the two sides. A count that differs between left and right is normal.

The glands do have a job. Their oily secretion lubricates and protects the areolar skin, which matters most during breastfeeding, when that skin takes repeated friction and moisture. Research from groups studying newborn behavior, published in journals such as Archives of Disease in Childhood and PLoS One, has found that secretions from these glands provoke head turning and mouthing in newborns and that mothers with more areolar glands reported somewhat faster early infant weight gain and lactation onset in first pregnancies. Those are small observational studies and the effect sizes are modest, but they make the same point from another direction: these are working structures, not leftover blemishes.

Three features of this anatomy shape every decision that follows:

• The glands are in the skin you would cut. A tubercle cannot be smoothed off like a mole sitting on top of the skin. Removing one means removing a small piece of areola and the gland beneath it, which leaves a small scar in pigmented tissue.
• Their size changes. A bump that looks prominent today may look different after a hormonal change, a pregnancy, or weight loss, which makes timing part of any decision.
• They can be blocked or inflamed. Like any sebaceous gland, a Montgomery gland can clog, swell into a small cyst, or become infected, and those are medical problems with their own management.

Why the bumps change: pregnancy, hormones, weight, and breast surgery

The short answer: Montgomery tubercles enlarge in response to estrogen and progesterone, so they are typically more visible during pregnancy and breastfeeding, sometimes with hormonal contraception or across the menstrual cycle, and occasionally after breast surgery changes the skin tension around the areola; most of that enlargement is reversible, but not always completely.

The most thoroughly documented trigger is pregnancy. Enlarged, darker tubercles are a classic early sign, listed in obstetric texts alongside areolar darkening, and they often appear within the first trimester. After breastfeeding ends they usually shrink, but many people find they stay a little more noticeable than before, much as the areola itself may stay darker or wider. That is part of why the timing advice in the piece on mommy makeover timing after pregnancy applies here as well: an areola examined six weeks after weaning is not the areola that will exist a year later.

Hormonal contraception, hormone therapy, and the normal menstrual cycle can produce smaller versions of the same change. Patients sometimes notice that the bumps are more prominent in the week before a period or after starting or switching a pill. The pattern is usually symmetric and fluctuating, which is reassuring. The interaction between hormonal medication and surgery more broadly is covered in birth control and hormone therapy before cosmetic surgery.

Breast surgery changes the picture in a few ways:

• Augmentation stretches the skin envelope. In many patients that flattens the tubercles slightly, but some patients notice them for the first time after surgery simply because they are looking at their areolas closely for the first time in years. Post-operative scrutiny is a real phenomenon, and a bump that was always there can feel new.
• Lifts and reductions reposition the nipple and areola and often reduce the areolar diameter by removing an outer ring of pigmented skin. Tubercles in that outer ring are removed with it, and the remaining ones can look more crowded on a smaller areola. The incision patterns themselves are described in breast lift incision patterns.
• Periareolar incisions for augmentation run along the areolar border, where tubercles often sit. Surgeons generally place the incision at the color junction and the glands are not a reason to avoid this approach, but a gland cut across at the edge can occasionally form a small cyst or a pinpoint sinus during healing. The tradeoffs of that incision are covered in choosing an augmentation incision.

A few drops of fluid from a tubercle, especially in the months after surgery, during pregnancy, or with hormonal change, is usually the gland doing what it was built to do. Fluid that is bloody, comes from the nipple itself rather than a tubercle, or comes from one spot on one side repeatedly is a different situation, discussed below.

"A Montgomery tubercle is not a blemish sitting on the areola. It is a gland opening through the areola, and taking it away means taking away a piece of the skin."

Montgomery cysts and inflamed glands: what usually happens and what treatment looks like

The short answer: a blocked Montgomery gland can form a small cyst behind the areola, most often in adolescent girls, and the published case series show that the large majority settle with observation, warm compresses, and antibiotics only if infected; surgery is reserved for abscesses that need draining or cysts that persist or recur, and an ultrasound is the usual test.

The classic presentation is a teenager, typically between about ten and seventeen, who notices a tender lump at the edge of the areola, sometimes with a reddened tubercle above it or a small amount of clear to brownish fluid leaking from it. Pediatric surgery and adolescent gynecology journals, including the Journal of Pediatric and Adolescent Gynecology and the Journal of Pediatric Surgery, have published case series on these retroareolar cysts. The consistent findings are that ultrasound shows a simple or slightly complex cyst just under the areola, that most resolve without surgery over weeks to a few months, and that a minority become infected and need antibiotics or, less commonly, drainage.

The reason this matters to a cosmetic audience is that the instinct to excise a breast lump in a young person runs the wrong way here. The developing breast bud sits directly beneath the areola in adolescence, and surgery in that area can damage it and cause lasting asymmetry, as the piece on facial and breast asymmetry explains. Conservative management is the standard because it works and because the downside of operating is real.

In adults, inflamed or cystic Montgomery glands are less common and are managed on similar principles:

• Warm compresses and leaving it alone are usually enough for a tender, slightly swollen tubercle. Squeezing tends to inflame the gland further.
• Antibiotics are used when there is spreading redness, warmth, or pus, typically aimed at skin bacteria. During breastfeeding, an inflamed gland is managed by the obstetric or lactation team alongside any mastitis concern.
• Drainage or excision is for an abscess or a cyst that keeps coming back. The approach is similar in spirit to the one for other skin cysts described in cyst and lipoma removal: if the gland lining is left behind, recurrence is likely.

A lump near the areola in an adult is also not automatically a Montgomery cyst. Fibroadenomas, ordinary breast cysts, duct ectasia, and in people with implants, capsule-related findings or silicone-related lymph node changes can all sit nearby. That is why an adult with a new firm lump should have it imaged rather than assumed, and why people with implants should know how breast imaging after implants and fat transfer works before they need it.

What can be done about prominent tubercles and areolar hair, and what each option costs you

The short answer: prominent tubercles can be reduced with small excisions, electrosurgery, or ablative laser, and hair around the areola can be reduced with laser hair removal or electrolysis, but every option works on thin, pigmented, sensitive skin where scarring and pigment change are the main risks, the evidence comes from small case reports rather than trials, and no option is a requirement for health.

There is no guideline from the American Society of Plastic Surgeons or the American Academy of Dermatology on cosmetic removal of Montgomery tubercles, and the published literature consists of case reports and small series. What follows is a description of the techniques in use and their tradeoffs, not a ranking.

Small surgical excision. A surgeon removes the tubercle and the gland beneath it with a tiny ellipse or punch and closes the skin with fine sutures. This is the most definitive option for an individual bump, because it removes the gland rather than just flattening its opening. The cost is a small scar for each bump removed. On the areola, a scar can heal paler or darker than the surrounding pigment, and the more bumps removed, the more the areola can look speckled with tiny marks rather than smooth.

Electrosurgery or ablative laser. Some dermatologists and plastic surgeons flatten tubercles with fine-tip electrosurgery or a carbon dioxide laser, vaporizing the raised portion. Case reports describe acceptable cosmetic results in selected patients, but these methods leave the deeper gland behind, so some bumps recur, and ablation creates a small wound that heals with the same pigment risks. The same principle applies to removing other small raised lesions, as discussed in seborrheic keratoses and skin tag removal.

Areola reduction. When the real concern is a large areola with tubercles concentrated in the outer ring, reducing the areola removes those bumps as part of the operation, with a single scar at the color junction. That is a larger operation with its own tradeoffs, including the tendency of a reduced areola to stretch back, all covered in the earlier piece on nipple and areola reduction.

Pigment and skin tone. On medium and deeper skin, the risk that any of these procedures leaves a light or dark mark is higher, and post-inflammatory darkening on the areola can take many months to fade. The general principles are laid out in cosmetic procedures on deeper skin tones. Patients with a history of keloids should treat any areolar procedure as a scar risk first, since the chest is one of the most keloid-prone areas of the body, as noted in scar care after plastic surgery.

Breastfeeding. Removing a handful of tubercles is unlikely to affect breastfeeding in a measurable way, since many glands remain. Removing many of them, or combining removal with an areola reduction, adds to whatever effect other breast surgery has already had. Anyone planning a future pregnancy should weigh this with the information in breastfeeding after breast surgery.

Hair is a separate concern that patients often raise in the same breath. A few dark hairs around the areola are common in people of every sex and are not a sign of disease on their own. Plucking them is the most common home approach and the most likely to cause ingrown hairs and small inflamed bumps, which then get mistaken for new tubercles. Waxing the areola is generally discouraged because the skin is thin.

The two methods that offer lasting reduction are laser hair removal and electrolysis. Laser works on the contrast between dark hair and lighter skin, and because the areola is pigmented, the contrast is lower and the burn and pigment risk is higher. Clinicians typically use longer-wavelength lasers such as Nd:YAG on darker areolar skin and conservative settings throughout, as the piece on laser hair removal and permanent reduction explains. Electrolysis treats each follicle individually, works regardless of pigment, and suits the small number of hairs typically present, at the cost of more sessions and some discomfort.

A notable increase in hair on the areola together with hair on the chin, upper lip, abdomen, or chest, irregular periods, or acne is worth raising with a primary care physician or endocrinologist, since it can reflect conditions such as polycystic ovary syndrome. That evaluation comes before cosmetic hair removal, not after.

When a change on the nipple or areola is not a cosmetic problem

The short answer: scaling, crusting, weeping, or a sore that starts on the nipple and does not heal, a new lump, new nipple inversion, skin dimpling, or spontaneous bloody discharge from one duct should be examined by a physician and may need imaging or a biopsy; these are uncommon, but they are the reason a cosmetic consult should never be the first stop for a changing areola.

The condition every clinician in this area keeps in mind is Paget disease of the breast, a form of breast cancer that shows up in the skin of the nipple. Organizations including the National Cancer Institute describe it as typically starting as redness, scaling, or crusting on the nipple, often on one side, sometimes with itching, burning, or a small amount of discharge, and gradually spreading onto the areola. In the large majority of cases there is an underlying cancer in the breast, sometimes without a palpable lump. It is often mistaken for eczema, and the delay that follows is the problem.

The practical distinctions that clinicians use, none of which replaces examination:

• Eczema of the nipple and areola is often on both sides, often starts on the areola rather than the nipple, tends to itch, and improves with a short course of a topical steroid. It is common in people with eczema elsewhere and in breastfeeding parents, and contact allergy to creams, detergents, or dressings can produce something similar, as described in adhesive and tape rash after surgery.
• Paget disease usually starts on the nipple itself, is usually on one side, and does not resolve with steroid treatment, or improves briefly and comes back. A rash on one nipple that has not cleared after a few weeks of appropriate treatment warrants a biopsy.

Other changes that move a concern out of the cosmetic category:

• A new, firm, or growing lump near or behind the areola in an adult.
• New inversion of a nipple that used to point outward, which is different from lifelong inversion, as explained in inverted nipple correction.
• Skin dimpling, puckering, or an orange-peel texture on the areola or nearby breast.
• Spontaneous discharge from one duct on one side, especially if it is bloody or clear and watery, rather than the oily or milky secretion of a tubercle.
• A pigmented spot on the areola that is new, changing, or irregular, which belongs to a dermatologist on the same logic described in cosmetic mole removal.

There are also benign conditions that look unusual enough to prompt a visit. Nevoid hyperkeratosis of the nipple and areola produces thickened, brownish, warty skin, usually on both sides, and is benign but stubborn, with limited treatment options. Accessory nipples and breast tissue along the line from the armpit to the groin can look like moles or bumps and are covered in accessory breast tissue. In men, Montgomery glands are present but usually smaller, and a domed or puffy areola is far more often a sign of gland underneath, the territory of gynecomastia surgery, than a problem with the tubercles.

A good cosmetic surgeon will look at a list of areolar concerns and sort it before discussing removal. If a surgeon proposes excising or lasering a lesion on the nipple or areola without sending it for pathology, or without asking how long it has been there and whether it has changed, that is worth a second consultation.

The honest summary

The small raised bumps on most areolas are Montgomery tubercles, the surface openings of glands that lubricate the skin and play a supporting role in breastfeeding. They vary in number from person to person and between the two sides, they enlarge with pregnancy and hormonal change, and they can become more noticeable, or simply more noticed, around breast surgery. None of that is a disease.

When a Montgomery gland blocks and forms a cyst, most often in adolescence, observation and warm compresses resolve the large majority, with antibiotics for infection and surgery reserved for abscesses or persistent cysts. Operating on the developing breast bud is the outcome everyone involved is trying to avoid.

Removing prominent tubercles is possible, by small excision, electrosurgery, ablative laser, or as part of an areola reduction. Each option trades a bump for a small scar in skin that is prone to pigment change, the evidence base is thin, and recurrence is common with methods that leave the gland behind. Hair around the areola is common and can be reduced with laser or electrolysis, with extra caution on darker areolar skin, and a broader pattern of new hair growth deserves a hormonal workup first.

What does not belong in a cosmetic conversation is a change that is new, one-sided, scaly, crusted, bleeding, or growing. A nipple rash that does not clear with treatment needs a biopsy, and a new lump needs imaging, before anyone discusses smoothing anything off.

The patient at the top of this piece had the tubercles examined at the breast consultation. Both areolas were symmetric in texture, the bumps had been present since adolescence, and nothing was scaly, crusted, or one-sided. The surgeon explained that removal was possible but would leave several small marks on each side, and suggested waiting six months after the recent change in contraception before deciding. By the follow-up visit the bumps had shrunk noticeably. The patient decided to leave them, went ahead with the volume and shape plan, and crossed the third item off the list. It was the right outcome not because removal is wrong, but because the decision was made about the glands as they actually were, rather than as they looked in one hormonal month.
