Melanoma in Women: Why You Need to Check Your Nails and Scalp

When people think about melanoma, they often picture a dark mole on the arm, leg, or face. While those are common places, they are not the only ones. In women, melanoma can appear in less obvious areas—especially the nails and scalp. These hidden locations are easy to overlook, which can delay diagnosis and treatment.

Understanding where melanoma can develop, what to look for, and when to speak to a doctor can make a real difference. This article explains why nail and scalp checks matter, what warning signs to watch for, and how to take action without panic or delay.

What Is Melanoma?

Melanoma is a serious form of skin cancer that starts in melanocytes—the cells that give skin, hair, and nails their color. While it is less common than other skin cancers, melanoma is more likely to spread if not found early.

The good news is that when melanoma is detected early, treatment is often very effective. Awareness and regular self-checks are key parts of prevention and early detection.

Why Melanoma Can Be Different in Women

Research shows that melanoma can present differently in women than in men. Women are:

• More likely to develop melanoma on the legs, scalp, and under nails
• Sometimes diagnosed later when melanoma appears in hidden or less-checked areas
• More likely to overlook nail and scalp changes because they do not match the typical "mole on the skin" image

Because of this, paying attention to these areas is especially important.

Melanoma Under the Nails: What You Should Know

Melanoma that forms under the nail is called subungual melanoma. It is rare, but it can be serious because it is often mistaken for harmless conditions.

Common Signs of Nail Melanoma

Look for the following changes in fingernails or toenails:

• A dark brown or black stripe running lengthwise down the nail
• A spot or streak that widens over time
• Pigment spreading into the surrounding cuticle or skin
• A nail that splits, cracks, or lifts without injury
• Bleeding, pain, or swelling around the nail
• A dark mark under the nail that does not grow out as the nail grows

Importantly, nail melanoma is not caused by nail polish, gel manicures, or nail trauma, although those factors can hide the signs.

Why It's Often Missed

• It may look like a bruise
• It often affects only one nail
• It can appear slowly and painlessly
• Many people don't regularly examine their nails closely

Melanoma on the Scalp: A Hidden Risk

The scalp is one of the most common places for melanoma to go unnoticed. Hair can hide changes in the skin, making them harder to see.

Why Scalp Melanoma Is Serious

• It is often diagnosed later
• It may grow deeper before being noticed
• It can be harder to treat if advanced

Signs to Watch For on the Scalp

• A new or changing mole or bump
• A sore that does not heal
• A spot that itches, bleeds, or crusts
• A lesion that looks different from others on your skin

Parting your hair in sections or asking a partner or stylist to look during hair care routines can help with early detection.

The ABCDEF Rule for Nail Melanoma

Doctors often use a simple guide to assess nail changes:

• A – Age (more common over 50, but can occur at any age)
• B – Brown or black band with irregular borders
• C – Change in size or appearance
• D – Digit involved (often thumb, big toe, or index finger)
• E – Extension of pigment into surrounding skin
• F – Family or personal history of melanoma

This is not a diagnosis tool, but it can help you decide when to seek medical advice.

Risk Factors Women Should Be Aware Of

Anyone can develop melanoma, but certain factors increase risk:

• Fair skin, light hair, or light eyes
• History of sunburns or tanning bed use
• Family history of melanoma
• Many moles or unusual moles
• Weakened immune system
• Age (risk increases over time)

Nail and scalp melanoma do not always relate to sun exposure, which is why they can catch people off guard.

Speak to a Doctor—Especially for Serious or Life-Threatening Concerns

If you notice:

• A rapidly changing nail or scalp lesion
• Bleeding, pain, or ulceration
• A dark streak or spot that is growing or spreading
• Any lesion that looks very different from others on your body

You should speak to a doctor, ideally a dermatologist, as soon as possible. Anything that could be life-threatening or serious deserves professional evaluation. Early diagnosis of melanoma can save lives.

Prevention Without Fear

Being aware of melanoma does not mean living in fear. It means being informed and proactive.

Simple habits can help:

• Use sun protection on exposed scalp areas
• Avoid tanning beds
• Schedule routine skin checks
• Include nails and scalp in monthly self-exams
• Trust your instincts if something looks "off"

Final Thoughts

Melanoma in women does not always appear where you expect it. The nails and scalp are often overlooked, yet they can be critical areas for early detection. By knowing what to look for, checking regularly, and taking action when something changes, you give yourself the best chance for a positive outcome.

Stay informed, stay observant, and always speak to a doctor about anything that feels serious or potentially life-threatening. Early attention is not overreacting—it is smart healthcare.
