Comprehensive Overview of Skin Cancer: Causes, Indicators, and Prevention

Skin cancer results from abnormal multiplication of skin cells and includes three primary types. The most common is basal cell carcinoma, followed by squamous cell carcinoma. Melanoma, though less frequent, poses the greatest danger. Other rare types encompass Merkel cell carcinoma and kaposi sarcoma, affecting different skin structures and tissues.

Causes: Genetic mutations in skin cells mainly cause skin cancer, often due to ultraviolet (UV) radiation from sun exposure or tanning devices. Damage can also occur without UV radiation, especially in individuals with weakened immune systems.

UV rays harm skin DNA, resulting in mutations that can lead to cancer. Risk factors include frequent sunburns, fair skin, light hair and eye color, freckles, living in sunny or high-altitude regions, family history of skin cancer, exposure to arsenic or radiation, atypical moles, and certain viral infections. A compromised immune system can also elevate risk.

Signs: Symptoms differ among types. Basal cell carcinoma may present as shiny bumps or flat brown patches. Squamous cell carcinoma appears as scaly or reddish growths. Melanoma often resembles irregular dark moles or spots that change size or color over time. Kaposi sarcoma shows purple or red patches, while Merkel cell carcinoma presents as shiny bumps. Any unusual skin lesion warrants medical attention.

Prevention & Treatment: Methods include surgical removal, radiation therapy, topical treatments, cryotherapy, and laser procedures. Protective measures like sunblock and limiting UV exposure can greatly lower risk.
