Why Do I Have Little Bumps Around My Nipples? Root Causes

Those small bumps around your nipples are most likely Montgomery glands — normal oil-producing glands that help keep the area lubricated. They become more visible during pregnancy, hormonal changes, or when irritated. Less common causes include clogged hair follicles, ingrown hairs, or minor skin infections. Understanding the difference helps you know when to leave them alone and when to see a clinician.

What Are Montgomery Glands?

Montgomery glands are tiny sebaceous glands located on the areola, the dark skin surrounding the nipple. They produce an oily substance that keeps the areola moist and protected. Everyone has them, though they are more noticeable in some people.

These glands often become more prominent during pregnancy, breastfeeding, or just before a menstrual period. Hormonal shifts cause them to enlarge. This is normal and does not require treatment. The bumps look like small pimples or goosebumps and are scattered around the areola.

Some people call them “tubercles” or “Montgomery tubercles.” The medical term is areolar glands. They are not a sign of disease. They serve a purpose: the oil they release has antibacterial properties and helps keep the skin barrier intact during breastfeeding.

Why Do I Have Little Bumps Around My Nipples That Look Like Pimples?

If the bumps look like pimples — red, white-tipped, or tender — the cause may be different from normal Montgomery glands. Clogged pores or follicles can develop into folliculitis, which is inflammation of a hair follicle. The areola has fine hairs, and irritation from shaving, friction, or tight clothing can cause small pimple-like bumps.

Another possibility is a sebaceous cyst. This happens when a sebaceous gland becomes blocked and fills with keratin. The bump feels smooth and firm under the skin. Sebaceous cysts are not dangerous but can become inflamed or infected.

Hidradenitis suppurativa is a chronic skin condition that causes painful bumps in areas with sweat glands, including the armpits, groin, and occasionally the breasts. It is less common but should be considered if bumps are recurrent, painful, or drain fluid.

If the bumps appear suddenly after using a new soap, lotion, or laundry detergent, contact dermatitis could be the cause. The skin reacts to an irritant or allergen, producing small red bumps that may itch or burn.

When Are These Bumps a Sign of Something Serious?

Most bumps around the nipples are harmless. However, certain features warrant a medical evaluation. A single bump that does not go away, grows, or feels hard and fixed to deeper tissue should be examined. So should bumps that bleed, ooze, or change color.

Inflammatory breast cancer is a rare but aggressive form of breast cancer that can present with skin changes rather than a lump. Symptoms include redness, swelling, warmth, and a dimpled or orange-peel appearance of the breast skin. Small bumps may appear, but they are usually part of a broader change rather than isolated spots.

Paget’s disease of the breast is another rare condition that begins in the nipple. It causes a red, scaly, crusted area that may look like eczema. The nipple can become flat or inverted. Itching and burning are common. Paget’s disease is almost always associated with an underlying breast cancer.

If you have any of these signs — a persistent non-healing sore, nipple discharge, skin retraction, or a hard lump deeper in the breast — see a healthcare provider promptly. Most breast changes are benign, but ruling out serious causes is important.

How Can You Tell the Difference Between Normal Bumps and Ones That Need Attention?

Normal Montgomery glands are symmetrical, multiple, and consistent in appearance. They do not hurt, bleed, or change rapidly. They vary slightly in size but remain small, usually 1–2 millimeters across. They are not red or inflamed unless irritated.

Bumps that need attention tend to stand out as different. They may be larger, tender, or solitary. They might appear suddenly and persist. A useful rule: if one bump looks notably different from the others around it — bigger, redder, harder — that one deserves a closer look.

Changes over time matter too. A bump that grows over weeks, develops a crust, or becomes painful is more concerning than one that stays the same for months. Keeping track of your breast skin each month during a self-exam can help you notice changes early.

Can You Treat or Remove These Bumps?

Normal Montgomery glands do not need treatment. Trying to pop or squeeze them can cause infection, scarring, or more visible inflammation. Leave them alone.

For folliculitis or other minor skin irritation, gentle care often resolves the issue. Stop any potential irritants — harsh soaps, tight bras, or excessive friction. Warm compresses can soothe inflammation. Over-the-counter hydrocortisone cream may help mild contact dermatitis, but check with a clinician before using it on breast skin.

For a sebaceous cyst that becomes infected, a doctor may recommend incision and drainage. Do not attempt this yourself. Infected bumps may require antibiotics.

If hidradenitis suppurativa is suspected, a dermatologist can create a treatment plan. Options include topical antibiotics, anti-inflammatory medications, and sometimes laser therapy or surgery. No evidence supports home remedies for this condition beyond warm compresses and weight management.

Surgical removal of Montgomery glands is rarely necessary and is not recommended unless a specific medical problem exists. The glands serve a function, and removing them can cause complications.

How Do Pregnancy and Breastfeeding Affect These Bumps?

Pregnancy causes Montgomery glands to become larger and more numerous. This is a normal response to rising hormone levels. The glands prepare for breastfeeding by producing more oil, which helps protect the nipple and areola from cracking and infection.

During breastfeeding, the bumps may stay prominent. Some women notice they get smaller after weaning. If a bump becomes painful or red during breastfeeding, it could be a blocked duct or mastitis, not the gland itself. Mastitis requires medical treatment.

Pregnant and breastfeeding women should not attempt to squeeze these bumps. The risk of introducing bacteria and causing an infection is higher during this time. If you are concerned about any bump, talk to your obstetrician or midwife.

What About Other Skin Conditions on the Areola?

Eczema and psoriasis can affect the areola, causing red, scaly, itchy patches. These are not bumps exactly but can be confused with them. Eczema is usually triggered by irritants or allergens. Psoriasis is an autoimmune condition. Both are managed with topical treatments.

Milia are tiny white cysts that can appear on the areola. They are harmless and go away on their own. They contain keratin and look like small whiteheads. Do not try to pop them.

Molluscum contagiosum is a viral skin infection that causes small, flesh-colored, dome-shaped bumps with a dimple in the center. It can spread to the breast area, especially in children or adults with weakened immune systems. It usually resolves without treatment but can be treated if persistent.

If you are unsure what you are seeing, a dermatologist can identify the condition by looking at it. Skin conditions on the areola are common and usually benign, but an accurate diagnosis helps avoid unnecessary worry.
