Breast Skin Dimpling: A Change That Needs a Look

What does breast skin dimpling actually mean?

Dimpling is an inward pull or pucker of the breast skin that stays in one place instead of smoothing out when you move or gently press nearby. Fibrous bands called Cooper's ligaments anchor the skin to the tissue underneath. When something below the surface shortens or tugs on those bands, the skin dents inward, much as a button pulls fabric. That is different from a surface rash or irritation, such as contact dermatitis, which affects the skin itself rather than its contour. A true dimple often becomes clearer when you raise an arm or lean forward, because the movement changes how the tethered skin is stretched and shadows the pucker.

What causes a dimple or pucker to appear?

Several conditions can tether breast skin, and many of them are not cancer. Benign causes include fat necrosis after a bruise, injury, or surgery, scarring from a previous procedure, or the pull of a large benign cyst or breast lump. A dimple can also form over an underlying breast cancer as it draws on nearby ligaments, and rapid puckering with redness can point to inflammatory breast cancer. About 1 in 8 women in the United States will develop breast cancer over a lifetime, according to the National Cancer Institute 1Ref 1National Cancer Institute (PDQ Screening and Prevention Editorial Board) (2025).Breast Cancer Screening.National Cancer Institute source for the lifetime breast cancer risk of about 1 in 8 women and for the role of clinical exam and mammographic imaging in evaluating breast findings, and a new area of skin tethering is one visible clue worth checking. A strong family history or an inherited BRCA gene change raises that baseline risk 3Ref 3National Cancer Institute (2024).BRCA Gene Changes: Cancer Risk and Genetic Testing Fact Sheet.National Cancer Institute source that a strong family history and inherited BRCA gene changes raise baseline breast cancer risk.

How can you check for dimpling at home?

A mirror check in good light is the simplest way to notice a change in breast contour. It helps to look in a few positions rather than one and to compare the two sides.

• With arms relaxed at your sides, look for any dent, pucker, or area that sits differently than before.
• Raise both arms overhead and watch for skin that pulls inward on one side.
• Press your hands onto your hips to tighten the chest muscles, then lean forward and look again.

Learning how to examine your breasts makes these changes easier to catch early. Breast tissue feels naturally lumpier and more nodular in the premenopausal years and around each cycle, and often softens after menopause, so a fixed dimple stands out against that normal, shifting texture at any age.

Does dimpling always mean a mammogram?

A visible skin change is evaluated in person first, and any imaging is chosen based on that exam. A clinician performs a clinical breast exam and may order a diagnostic mammogram, an ultrasound, or both, depending on your age and what they feel. This is different from routine screening: the American College of Obstetricians and Gynecologists recommends offering screening mammography starting at age 40, usually every 1 to 2 years for women at average risk 2Ref 2American College of Obstetricians and Gynecologists (2017).Practice Bulletin Number 179: Breast Cancer Risk Assessment and Screening in Average-Risk Women.ACOG guidance that screening mammography is offered to average-risk women starting at age 40, typically every 1 to 2 years, and that benign breast changes are common. A new dimple, though, is a diagnostic question rather than a screening one, so it may be looked at sooner regardless of when your last routine mammogram was done.

When breast dimpling needs an in-person exam

Breast dimpling that is new, stays in one spot, or appears alongside a lump, nipple change, or skin thickening is a reason to book a visit rather than wait to see whether it fades. The large majority of breast changes turn out to be benign, but skin tethering is the kind of change clinicians prefer to examine promptly rather than watch. Within 1 to 2 weeks is a reasonable timeframe for a change that is not painful or spreading, and sooner if other symptoms appear. Gale can help you organize what you have noticed, including when the dimple showed up and how it has changed, before that conversation.
