Causes and Risk Factors: Who Is Most Vulnerable
Chronic sun exposure is the main cause, particularly for fair-skinned, light-eyed individuals. Other risks include burns, scars, chemical exposure, chronic inflammation, and weakened immune systems. SCC can also appear in darker skin, often in previously damaged or inflamed areas.
• Over 250,000 Americans develop SCC each year, making early recognition essential.
• Fair skin and repeated sun exposure significantly increase lifetime risk of SCC.



Recognizing Warning Signs: Early Symptoms to Spot Before Progression
SCC can appear as scaly red patches, raised bumps with central depressions, open sores, or wart-like growths. Lesions may bleed, crust, or enlarge over weeks. High-risk locations include the face, ears, hands, forearms, and lips.
Regular self-checks and prompt evaluation of suspicious spots help detect SCC early, allowing simpler treatment, less tissue damage, and improved long-term results. Images help patients recognize potential SCC changes at home and seek care quickly.
