Breast dimpling refers to a small, often shallow indentation or dimpling of the skin that can appear on one or both breasts. This change may be noticeable in certain positions, when the skin is gently pulled, or on imaging. While occasional minor dimpling can be a normal variant, new, persistent, or worsening dimpling can sometimes be linked with underlying structural or inflammatory changes. This explainer covers common causes, what clinicians look for during evaluation, and the steps you can take if you notice changes in your breast skin.
What Is Breast Dimpling and How It Appears
Breast dimpling is a visible change in the skin surface where a small area appears inset or indented compared with the surrounding tissue. It is often described as resembling a small depression or a slight “orange peel” texture in a localized spot. The change can be intermittent or constant and may become more apparent when the arm is raised or when gentle lateral pressure is applied. Clinically, providers assess dimpling in relation to other skin or shape changes, symmetry, and any associated symptoms such as pain or discharge.
Common Causes of Breast Dimpling
Several factors can contribute to the appearance of breast dimpling, ranging from harmless, temporary changes to conditions that warrant medical follow-up. Understanding the likely cause begins with how the dimpling developed, whether it is new or long-standing, and whether there are additional findings.
Normal Anatomy and Postural Changes
Minor skin dimpling can occur normally in some people due to the underlying pattern of connective tissue beneath the skin. Temporary dimpling may be more noticeable after certain postures, pressure during sleep, or minor trauma. These variations typically remain stable over time and are not associated with other symptoms.
Fibrocystic Changes and Cysts
Fibrocystic breast changes, which include general lumpiness, cysts, and fibrosis, can sometimes cause subtle shifts in breast contour. If a cyst is large or located just beneath the skin, it may create a localized dimpling effect. Such changes often fluctuate with the menstrual cycle and may be accompanied by tenderness.
Fat Necrosis
Fat necrosis is a benign condition where damaged fat tissue in the breast forms firm lumps or areas of scarring. It can occur after injury, surgery, or radiation. As the damaged fat is replaced by scar tissue, the skin over the area may dimple or retract slightly. Fat necrosis is usually painless but can sometimes be confused with other findings on exam or imaging.
Mastitis and Inflammatory Changes
Inflammation of breast tissue, whether due to infection (infectious mastitis) or other causes, can lead to localized skin dimpling if swelling and scarring affect the overlying skin. Inflammatory changes may be accompanied by redness, warmth, pain, or fever, and often respond to appropriate treatment.
Prior Biopsies, Surgeries, or Radiation
Previous procedures or radiation therapy can alter the breast architecture, leading to scarring and localized skin dimpling. These changes are typically stable and are part of a known medical history. Any new change in an area of prior treatment should still be reviewed by a clinician.
Rare but Important Considerations
Although uncommon, new skin dimpling can be a sign of an underlying breast condition that requires prompt attention. This is particularly relevant when dimpling is new, progressive, or accompanied by other findings. Clinicians evaluate these situations carefully to determine the appropriate next steps.
When to Seek Medical Evaluation
Not every instance of breast dimpling is a cause for concern, but certain features suggest the need for a clinical assessment. If you notice new dimpling, changes in existing dimpling, or any associated symptoms, contacting a healthcare provider is a reasonable and helpful step.
Features That Suggest Prompt Evaluation
- New dimpling that appears and does not improve over several menstrual cycles
- Dimpling accompanied by a new or changing breast lump
- Skin redness, warmth, or pain along with dimpling
- Nipple changes, such as inversion or discharge, especially if bloody
- Dimpling that progresses or becomes more noticeable over time
Clinical Evaluation and Diagnostic Steps
When you seek care for breast dimpling, clinicians typically begin with a thorough history and physical examination, which includes breast palpation and assessment of skin changes. Based on findings, targeted imaging or additional testing may be recommended to clarify the cause.
What to Expect During a Clinical Visit
Your provider will ask when the dimpling began, whether it is constant or intermittent, and if there are other symptoms such as pain, discharge, or changes in your menstrual cycle. They will examine both breasts for symmetry, skin changes, lumps, and areas of tenderness. They will also consider your personal and family medical history.
Imaging and Further Testing
Imaging can help characterize the cause of dimpling. Many people undergo a combination of tests, such as:
| Modality | Purpose | Typical Findings That Matter |
|---|---|---|
| Diagnostic Mammogram | Visualize breast tissue and detect abnormalities | Masses, architectural distortion, skin thickening |
| Breast Ultrasound | Characterize lumps and distinguish solid from fluid-filled areas | Cysts, solid masses, complex lesions |
| MRI (when indicated) | Provide detailed soft tissue evaluation | Suspicious enhancing lesions, extent of known disease |
If imaging raises concern, a biopsy may be recommended to obtain tissue samples for microscopic evaluation. The type of biopsy—core needle, vacuum-assisted, or surgical—depends on the imaging findings and clinical context.
Reassuring Findings and Benign Patterns
Many people with breast dimpling have benign findings on evaluation. Stable, long-standing dimpling without other concerning features often reflects normal anatomic variation or prior minor trauma. When imaging and exams show reassuring features, clinicians may recommend routine follow-up with self awareness and periodic clinical exams.
Examples of Benign Patterns
- Slight unilateral or bilateral dimpling present for many years with no change
- Dimpling that fluctuates with the menstrual cycle and is associated with generalized lumpiness
- Stable dimpling noted after known trauma or surgery, with imaging showing no concerning features
Next Steps and Self Care
If you are experiencing breast dimpling, practical steps include tracking any changes, noting when the dimpling is most apparent, and recording any additional symptoms. Scheduling a visit with your primary care provider or a breast specialist can help clarify the cause and determine whether further testing is needed. In the meantime, maintaining regular breast self awareness and attending age-appropriate screening appointments supports overall breast health.
Summary and Key Takeaways
Breast dimpling is a descriptive change in skin contour that can have a variety of causes, from normal anatomy to conditions that require medical evaluation. New, progressive, or symptomatic dimpling should prompt a clinical visit, where history, examination, and possibly imaging can clarify the underlying reason. Most cases are benign, but a careful, individualized assessment ensures that important findings are identified and managed appropriately.
