Noticing a breast indentation when arm is raised can be both confusing and concerning. These subtle changes are often overlooked, but they can sometimes signal underlying issues that require medical attention. Before jumping to conclusions, it is important to understand what breast indentation really is and why it may occur.

Breast indentation refers to a visible dip, dent, or concave area on the surface of the breast. This change becomes more noticeable when the arm is lifted because the motion stretches the skin and underlying tissue, revealing irregularities that might not be obvious when at rest. The indentation can occur due to various reasons—some completely harmless, such as natural tissue changes or previous injuries, and others more serious, like underlying tumors pulling on the ligaments or skin from within.

While not every indentation is cause for alarm, it is always worth paying attention to changes in breast symmetry, contour, or skin texture—especially if they are new, worsening, or accompanied by other symptoms.

“One of the earliest signs of breast cancer isn’t always a lump—it can be a subtle indentation or dimpling that only appears when the arm is raised. These signs can be easy to miss, which is why awareness is so important.”
 – Dr. Garvit Chitkara, a seasoned breast cancer surgeon in Mumbai

 Now, let’s understand the reason behind the indentation.

Why Does Indentation Appear When You Raise Your Arm?

The structure of the breast includes fatty tissue, glands, ducts, and ligaments, all of which are connected to the skin. When you raise your arm, the skin and tissues stretch, making subtle indentations more noticeable. These indentations can be caused by:

• Fibrous tissue pulling on the skin
• Changes in breast fat distribution
• Scar tissue or previous surgery
• Trauma or injury to breast tissue

In many cases, the cause is benign. However, if the indentation is new or accompanied by other changes, it may be worth a closer look.

Here’s what you need to know.

Could It Be a Sign of Breast Cancer?

A breast indentation when arm is raised can, in some cases, be an early sign of breast cancer. Certain types of breast tumors grow in a way that tugs at surrounding tissue, creating a tethering effect that pulls the skin inward.

Dr. Garvit Chitkara, a breast oncology surgeon in Mumbai, emphasizes,

“One of the lesser-known symptoms of breast cancer is skin dimpling or indentation. It often appears before any lump is felt.”

While not all indentations point to cancer, it is important to consider them within the broader context of breast health.

Watch out for these red flags.

Other Symptoms to Watch For

If you observe a breast indentation when arm raised, check for other accompanying signs, including:

• A palpable lump
• Changes in skin texture (like an orange peel appearance)
• Nipple discharge
• Unexplained swelling or shrinking of the breast
• Redness or skin irritation
• Nipple inversion or sudden changes in position

Any combination of these symptoms should be assessed by a medical professional promptly.

What to Do If You Notice Indentation When You Lift Your Arm

If you see a breast indentation, don’t panic. Here’s what you can do:

Self-examine thoroughly:
Use a mirror to observe your breasts in different positions—arms down, arms raised, and hands pressed on hips.

Document the change:
Take note of when you first noticed the indentation, whether it is persistent, and if other symptoms have developed.

Avoid jumping to conclusions:
Not all changes are malignant. Hormonal shifts, weight changes, and benign cysts can also cause visible differences.

Schedule a clinical exam:
Get it checked by a specialist, preferably someone with experience in breast oncology, like Dr. Garvit Chitkara, who has managed hundreds of complex breast cases.

• There is a family history of breast cancer
• You are experiencing unexplained breast pain or nipple discharge

Prompt medical evaluation can help detect any serious conditions early and initiate appropriate care.
