Squamous Cell Carcinoma: Essential Signs & Next Steps for Women 30–45

Squamous cell carcinoma (SCC) is a common type of skin cancer that develops in the squamous cells—the thin, flat cells that make up the outer layer of the skin. While it is more common after age 50, women between 30 and 45 are not immune. In fact, rising sun exposure, indoor tanning, and immune-related conditions have increased risk in younger adults.

The good news: When found early, squamous cell carcinoma is highly treatable. The key is knowing what to look for and acting promptly.

What Is Squamous Cell Carcinoma?

Squamous cell carcinoma is the second most common type of skin cancer, after basal cell carcinoma. It usually appears on areas exposed to the sun, including:

• Face
• Lips
• Ears
• Neck
• Chest
• Arms and hands
• Legs

However, SCC can also develop in less expected areas, such as the genital region or inside the mouth.

Squamous cells normally help form a protective barrier for your skin. When these cells are damaged—most often by ultraviolet (UV) radiation from the sun or tanning beds—they can grow abnormally and form cancer.

Why Women 30–45 Should Pay Attention

Many women in this age group:

• Spent years tanning (outdoor or tanning beds)
• Use minimal daily sun protection
• Have busy schedules and delay skin checks
• Assume skin cancer only affects older adults

But early sun damage often shows up in your 30s and 40s. Skin cancers can also develop more aggressively in people with:

• Fair skin, light eyes, or red/blonde hair
• A history of blistering sunburns
• Frequent tanning bed use
• Weakened immune systems
• Human papillomavirus (HPV) infection (for certain genital or oral SCCs)

Essential Signs of Squamous Cell Carcinoma

Squamous cell carcinoma does not always look dramatic. In many cases, it resembles a minor skin issue that doesn't heal.

Common Warning Signs

Watch for:

• A scaly red patch that feels rough or crusty
• An open sore that doesn't heal within several weeks
• A raised growth with a central depression
• A wart-like lesion
• A thickened or firm bump
• A sore that bleeds easily
• A crusted spot on the lip that doesn't improve

SCC may also feel:

• Tender
• Painful
• Itchy
• Sensitive when touched

If a spot keeps coming back in the same location, that's another red flag.

How Squamous Cell Carcinoma Differs from Other Skin Cancers

It helps to understand the differences:

• Basal cell carcinoma: Often looks pearly or shiny and grows slowly.
• Melanoma: Usually appears as a dark, irregular mole.
• Squamous cell carcinoma: Often scaly, crusted, or thickened.

Unlike basal cell carcinoma, squamous cell carcinoma has a higher chance of spreading (metastasizing) if left untreated. While this is still uncommon, especially in early cases, advanced SCC can spread to lymph nodes and other organs.

This is why early detection matters.

What Is Keratoacanthoma?

You may also hear about keratoacanthomas, which are closely related to squamous cell carcinoma.

Keratoacanthomas:

• Grow rapidly over weeks
• Appear dome-shaped with a central plug of keratin
• Often resemble SCC

Because it's difficult to distinguish them without testing, doctors often treat keratoacanthomas similarly to squamous cell carcinoma.

If you've noticed any unusual skin changes and want to better understand your symptoms before scheduling an appointment, you can use a free Squamous Cell Carcinoma and Keratoacanthomas symptom checker to help determine whether you should seek immediate medical attention.

When to See a Doctor

You should speak to a doctor if:

• A skin lesion lasts more than 2–4 weeks
• A spot grows quickly
• It bleeds repeatedly
• It becomes painful
• You notice swelling in nearby lymph nodes
• A sore heals and then reopens

Even if the spot seems small, don't wait. Early evaluation can prevent complications.

Any symptom that could be serious or life-threatening deserves professional evaluation. Always speak to a doctor about concerns involving persistent skin changes.

How Squamous Cell Carcinoma Is Diagnosed

If your healthcare provider suspects squamous cell carcinoma, they will:

1. Perform a skin examination
2. Possibly use a dermatoscope (a magnifying tool)
3. Take a skin biopsy

A biopsy is the only way to confirm the diagnosis. The procedure is usually quick and done in the office under local anesthesia.

If SCC is confirmed, further evaluation may be needed in higher-risk cases to determine whether it has spread.

Treatment Options

Treatment depends on:

• Size of the tumor
• Location
• Depth of invasion
• Whether it has spread
• Your overall health

Common Treatments

• Surgical excision – The tumor is cut out with a margin of healthy tissue.
• Mohs surgery – Tissue is removed layer by layer and examined immediately. This is often used for facial areas to preserve healthy skin.
• Curettage and electrodesiccation – Scraping and burning the lesion (for small, early SCC).
• Radiation therapy – Sometimes used if surgery isn't possible.
• Topical medications – In select superficial cases.

When treated early, cure rates are high—often above 90%.

What Happens If It's Not Treated?

Without treatment, squamous cell carcinoma can:

• Grow larger and deeper
• Damage nearby tissue
• Spread to lymph nodes
• Spread to distant organs (rare but serious)

Advanced SCC can become life-threatening. While most cases are caught early, ignoring persistent skin changes increases risk.

Prevention Steps for Women 30–45

You cannot undo past sun exposure, but you can reduce future risk.

Daily Protection Habits

• Use broad-spectrum SPF 30+ sunscreen every day
• Reapply sunscreen every 2 hours outdoors
• Wear hats and protective clothing
• Avoid tanning beds entirely
• Seek shade during peak sun hours (10 a.m.–4 p.m.)

Monthly Skin Checks

Perform a full-body self-exam once a month:

• Use a mirror for hard-to-see areas
• Check scalp, between toes, under breasts
• Note new or changing lesions

Take photos to track changes.

Professional Skin Exams

Women with higher risk should consider yearly dermatology visits.

Emotional Side: Staying Calm but Proactive

Hearing the word "carcinoma" can feel overwhelming. But it's important to remember:

• Squamous cell carcinoma is common
• It is often slow-growing
• It is highly treatable when detected early
• You have control over prevention and early action

The goal is awareness—not fear.

Key Takeaways

• Squamous cell carcinoma is a common skin cancer that can affect women 30–45.
• Look for scaly patches, non-healing sores, firm bumps, or wart-like growths.
• Early treatment leads to excellent outcomes.
• Any lesion that persists or grows should be evaluated.
• Prevention through sun protection is critical.

If you're experiencing concerning symptoms and want quick guidance on whether to see a doctor, a free Squamous Cell Carcinoma and Keratoacanthomas symptom checker can help you assess your risk and make informed decisions about your next steps.

Most importantly, speak to a doctor promptly about any skin change that could be serious or life-threatening. Early evaluation is the safest and smartest next step.
