Skin cancer prevention and screening.

Area of Science:

• Dermatology
• Oncology

Background:

• Skin cancer is the most common malignancy globally.
• Risk factors include excessive solar/ultraviolet (UV) exposure, chronic injury, genetics, and pigmentation.
• Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are common types, while malignant melanoma, though rarer, causes most deaths.

Purpose of the Study:

• To summarize the etiology, clinical presentation, and risk factors of common skin cancers.
• To highlight the role of UV radiation and other irritants in skin carcinogenesis.
• To emphasize preventative measures and the importance of screening.

Main Methods:

• Review of existing literature on skin cancer epidemiology and risk factors.
• Analysis of clinical characteristics differentiating BCC, SCC, and melanoma.
• Synthesis of current recommendations for prevention and early detection.

Main Results:

• UV light is the primary carcinogen; chronic irritation also increases risk.
• BCC is more common in lighter skin, SCC in darker skin; melanoma has the highest mortality.
• Sunscreen use, avoiding tanning devices, and regular screening are strongly supported preventative strategies.

Conclusions:

• Skin cancer development is multifactorial, involving genetic predisposition and environmental exposures.
• Public health efforts should focus on sun protection and awareness of high-risk individuals.
• Adherence to sun safety guidelines and vigilance for suspicious lesions are crucial for reducing skin cancer incidence and mortality.
