Understanding Skin Cancer: Causes and Risk Factors
Skin cancer is a condition in which abnormal skin cells grow uncontrollably, often due to DNA damage caused by ultraviolet (UV) radiation from the sun or tanning beds. While sun exposure is the most significant risk factor, genetic predisposition, skin type, and environmental factors also contribute to its development. The disease encompasses three main types: basal cell carcinoma, squamous cell carcinoma, and melanoma. Each type varies in severity and progression, but all require prompt attention to prevent complications.
Basal cell carcinoma, the most common form, generally grows slowly and rarely spreads, making it easier to treat when detected early. Squamous cell carcinoma, while more aggressive, can also be successfully treated with early intervention. Melanoma, though less common, is the most serious type due to its potential to spread to other parts of the body.
Proactive measures such as regular skin checks, avoiding UV exposure, and using sun protection can significantly reduce the risk of developing skin cancer. Early detection and proper management are crucial for positive outcomes, making routine dermatological evaluations essential for maintaining skin health.
Recognizing the Signs of Skin Cancer
Signs and symptoms of skin cancer include:
Basal Cell Carcinoma:
Pearly or translucent bumps
Open sores that don’t heal
Reddish, irritated patches of skin
Squamous Cell Carcinoma:
Thickened, scaly patches of skin
Wart-like growths
Open sores that bleed or crust
Melanoma:
Irregular, asymmetrical moles
Changes in mole size, shape, or color (ABCDE Rule: Asymmetry, Border, Color, Diameter, Evolving)
Dark spots or streaks under nails
What Causes Skin Cancer?
The primary causes of skin cancer include:
UV Radiation: Unprotected exposure to sunlight or tanning beds damages the DNA in skin cells.
Genetics: A family history of skin cancer increases your susceptibility.
Weakened Immune System: Certain medical conditions or treatments that suppress immunity can elevate your risk.
Fair Skin and Light Hair: These traits make individuals more prone to UV damage.
What are Some Possible Treatments for Skin Cancer?
The treatment approach depends on the type and stage of skin cancer. At Summerlin Dermatology, we offer:
Biopsies: Performed in-office to diagnose the type and extent of cancer.
Cryotherapy: Freezing small cancerous lesions with liquid nitrogen.
Excision Surgery: Removing cancerous tissue and surrounding healthy skin for clear margins.
Mohs Surgery: A precise technique often used for BCC and SCC to minimize scarring and ensure complete removal.
Topical Medications: Such as 5-fluorouracil (5-FU) for early-stage BCC and SCC.
Photodynamic Therapy: A non-invasive treatment using light and a photosensitizing agent.
Advanced Melanoma Treatments: These may include immunotherapy or targeted therapy in collaboration with oncology specialists.
Prevention and Early Detection Tips
Taking proactive measures can significantly reduce your risk of skin cancer:
Daily Sunscreen Use: Apply broad-spectrum sunscreen with SPF 30 or higher to all exposed areas.
Protective Clothing: Wear hats, sunglasses, and UV-blocking apparel when outdoors.
Avoid Tanning Beds: These emit harmful UV rays and significantly increase your risk.
Perform Monthly Skin Checks: Use a mirror to examine hard-to-see areas for any changes or abnormalities.
Annual Dermatologist Visits: Regular screenings can catch skin cancer in its earliest stages.
