Newly Inverted Nipples: What Causes Them—and When to See a Doctor

Nipple inversion or retraction—where the nipple pulls inward instead of pointing outward—is more common than you might think. For many people, inverted nipples are a harmless, lifelong feature. But if you notice a new change in nipple appearance as an adult, it could be a sign of an underlying medical condition, including breast cancer. Here’s what you should know.

What Are Inverted Nipples?

Inverted nipples occur when the nipple is pulled inward toward the breast instead of protruding outward. This may affect one or both nipples and can be either congenital (present from birth) or acquired later in life.

• Flat nipples lie flush with the breast surface
• Inverted nipples turn inward toward the breast tissue
• Nipple retraction refers to when only part of the nipple is drawn inward

If your nipples have always looked this way, it’s likely not a medical concern. However, newly inverted nipples should always be evaluated.

Common Causes of Inverted Nipples

1. Congenital Factors

Some people are born with tight connective tissue or underdeveloped milk ducts that pull the nipple inward.

2. Hormonal Changes or Aging

As people age or go through menopause, structural changes in the breast tissue can lead to nipple retraction.

3. Breast Cancer

Sudden nipple inversion—especially if it's only on one side—can be a symptom of breast cancer, including a rare type called Paget’s disease.

4. Breast Infections or Inflammation

• Periductal mastitis (inflammation of the milk ducts)
• Duct ectasia (thickened and widened milk ducts)
• Trauma or surgery can also cause tissue changes and retraction

When to Seek Medical Care

If your nipple has suddenly inverted—especially without prior injury or explanation—it’s essential to talk to a healthcare provider. This is especially important if accompanied by:

• Discharge from the nipple
• Breast pain or lumps
• Skin changes such as dimpling or redness
• Changes to the areola

‍Schedule a consultation with a BASS primary care provider or contact the BASS Cancer Center if you are concerned about possible signs of breast cancer.

How Inverted Nipples Are Diagnosed

Doctors typically begin with a physical exam and may recommend one or more of the following imaging tests:

• Mammogram
• Breast ultrasound
• Breast MRI
• Needle biopsy (if cancer is suspected)

Regular breast exams and mammograms are crucial for early detection of breast cancer and other abnormalities. At BASS Imaging Center, we offer advanced diagnostic services—including same-day mammograms and breast imaging—to support your ongoing health.

Can Inverted Nipples Be Treated?

For Breastfeeding:

If inverted nipples interfere with breastfeeding, working with a lactation consultant may help. Suction devices or nipple shields can help draw the nipple outward.

Non-Surgical Methods:

• Nipple stimulation exercises (e.g., Hoffman technique)
• Consistent suction with at-home tools
• Piercing (not typically recommended, especially if you plan to breastfeed)

Surgical Options:

For cosmetic or functional reasons, minor outpatient procedures can correct persistent nipple inversion. Speak with your doctor about your options.

Are Inverted Nipples Common?

Yes—flat or inverted nipples affect approximately 10–20% of people and are usually benign. However, sudden nipple changes are always worth checking out.
