What is Carcinoma Skin Cancer? A Guide to Types, Symptoms & Treatment
Carcinoma skin cancer is the most common form of skin cancer in the United States, and chances are, you or someone you know has been affected by it. Unlike melanoma, which often gets more attention due to its severity, carcinoma includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)—both of which can be serious if ignored. If you’re wondering what carcinoma skin cancer really is and how to recognize and prevent it, you’re in the right place.
Understanding Carcinoma Skin Cancer
Carcinoma refers to cancers that begin in the epithelial cells—those found in the skin or in the lining of internal organs. In the context of skin cancer, we’re mainly talking about:
- Basal Cell Carcinoma (BCC): Arises from basal cells in the skin’s lower epidermis. It’s slow-growing and rarely spreads, but can cause significant local damage.
- Squamous Cell Carcinoma (SCC): Develops from squamous cells in the upper epidermis. It can grow more aggressively than BCC and may spread if not treated early.
Both fall under the umbrella of non-melanoma skin cancer. They’re highly treatable—especially when caught early.
What Causes Carcinoma Skin Cancer?
The biggest culprit? Ultraviolet (UV) radiation from the sun or tanning beds. Other causes include:
- Fair skin or light-colored eyes and hair
- History of frequent sunburns
- Older age (risk increases after 50)
- Chronic exposure to toxic substances (e.g., arsenic)
- Weakened immune system
- Family history of skin cancer
Symptoms and Warning Signs to Watch For
Knowing what carcinoma looks like can help save your skin—literally. Here’s what to keep an eye on:
- Pearly or waxy bump (especially for BCC)
- Flat, flesh-colored or brown scar-like lesion
- Red, firm nodule (common in SCC)
- Scaly patches that crust or bleed
- Sores that don’t heal within a few weeks
If you notice anything unusual on your skin that’s new or changing, get it checked.
Diagnosis and When to See a Dermatologist
Early detection is key. Your doctor may perform:
- Skin exam: Full-body check for moles, lesions, and growths
- Biopsy: Removing part of the suspicious area for lab testing
- Dermatoscopy: A non-invasive tool to closely examine skin lesions
The earlier you act, the easier and more effective the treatment.
How Is Carcinoma Treated?
Treatment depends on the cancer type, size, and depth. Common methods include:
- Excisional surgery: Cutting out the cancerous tissue
- Mohs surgery: Layer-by-layer removal, great for facial areas
- Cryotherapy: Freezing small tumors with liquid nitrogen
- Radiation therapy: For cases where surgery isn’t possible
- Topical treatments: Prescription creams for superficial BCCs
Basal cell carcinomas are almost always curable. Squamous cell carcinomas, when caught early, are also very treatable with high success rates.
Real Stories: Why Early Detection Matters
"I ignored the scab on my forehead for months. I thought it was just dry skin. Turned out to be squamous cell carcinoma. Luckily, I caught it in time." – Ryan, 41
"I used tanning beds in college. At 35, I had a spot on my chest removed. It was BCC. Now I wear sunscreen daily." – Mia, 37
Can Carcinoma Skin Cancer Come Back?
Yes, recurrence is possible—especially if sun safety habits don’t change. People who’ve had one carcinoma are at higher risk of developing another.
Prevention Tips: Protecting Your Skin
- Apply broad-spectrum SPF 30+ sunscreen every day
- Wear protective clothing and sunglasses outdoors
- Avoid tanning beds—seriously
- Seek shade during peak sun hours (10am–4pm)
- Check your skin monthly for changes
