Seborrheic Keratosis

What it is

A seborrheic keratosis is a very common and harmless skin growth. They often look like waxy or wart-like spots that are tan, brown, or black. These growths appear on the surface of the skin and are not related to the breast tissue underneath.

How common it is

These spots are very common, and you are more likely to get them as you get older. Many people have at least one.

What you may notice

You might see a single spot or a group of spots on your breast skin. They can be flat or raised and sometimes feel a little greasy or crumbly. Sometimes, they can get itchy or irritated by clothing.

What can contribute

Getting older is the main reason these spots appear. Your genetics and how much sun exposure you have had over your life can also play a role.

How it is usually checked

A provider can usually identify a seborrheic keratosis just by looking at it. If they are not sure what the spot is, they may look at it with a special magnifying tool. Sometimes they may suggest removing a small piece of skin, called a biopsy, to be sure.

Does this change my long-term risk?

A seborrheic keratosis is a harmless skin condition. It does not change your long-term breast health risk.

Comfort and everyday care

• Try wearing soft, loose-fitting bras and tops to avoid rubbing that can cause irritation.
• Keeping your skin well-moisturized may help with any itchiness.
• Using sunscreen can help reduce the number of new spots that form over time.
