Skin Cancer on the Scalp: What You Need to Know

When we think about skin cancer, we often picture sun-exposed areas like the face, arms, or legs. But did you know that skin cancer can also develop on the scalp? Because it’s often hidden under hair, it can be harder to detect, making early diagnosis even more crucial.

Can Skin Cancer Occur on the Scalp?

Absolutely. Skin cancers, including melanoma, can develop anywhere on the body, including the scalp. Melanomas arise from melanocytes—pigment-producing cells found in the skin—which means they can appear even in areas covered by hair.

Should You Be Concerned About a Mole on Your Scalp?

If you’ve recently noticed a new mole on your scalp or if an existing mole has changed in size, shape, or color, it’s essential to get it checked by a dermatologist as soon as possible. Melanoma, one of the most aggressive forms of skin cancer, can develop on the scalp, and studies suggest that scalp and neck melanomas are nearly twice as deadly as those found elsewhere on the body.

Why Are Scalp Melanomas More Dangerous?

Scalp melanomas tend to be more dangerous for several reasons:

• Delayed Detection: Because they’re often hidden by hair, scalp melanomas may not be noticed until they’re more advanced.
• Rich Blood Supply: The scalp has a dense network of blood vessels and lymphatics, which may contribute to faster cancer spread.

This makes regular skin checks—either by yourself, a partner, or a healthcare professional—especially important.

Can Other Types of Skin Cancer Occur on the Scalp?

Yes. In addition to melanoma, two other common types of skin cancer can develop on the scalp:

• Basal Cell Carcinoma (BCC): Typically appears as a pink or flesh-colored spot that may be flat or raised. It may bleed easily, even with minor trauma, and larger BCCs may have visible blood vessels on the surface.
• Squamous Cell Carcinoma (SCC): Can present as a rough, scaly patch or a sore that doesn’t heal. It may become crusty, red, or tender over time.

What Do Scalp Skin Cancers Look Like?

The appearance of skin cancer on the scalp varies depending on the type:

• Basal Cell Carcinoma (BCC): A pink or shiny spot that can be flat, raised, or crusty. It may bleed easily and sometimes has visible, irregular blood vessels.
• Squamous Cell Carcinoma (SCC): A red, scaly, or crusty patch that may grow and spread if left untreated.
• Melanoma: Can appear as a new or changing mole with irregular borders, multiple colors, or an asymmetrical shape.

What Should You Do?

If you notice any suspicious spots, moles, or sores on your scalp that don’t heal, grow, or change in appearance, schedule a skin check with a dermatologist. Early detection is key to successful treatment.

Additionally, wearing a hat, applying sunscreen to your scalp (especially if you have thinning hair), and regularly checking your scalp can help protect you from skin cancer.
