What is Skin Cancer?
Skin cancer is one of the most prevalent types of cancer, affecting millions of people worldwide each year. It occurs when skin cells begin to grow uncontrollably, often due to excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds. Understanding the different types of skin cancer and their risk factors is crucial for prevention and early detection.
Types and Symptoms of Skin Cancer
The most common types of skin cancer include basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma appears as a pearly bump or a flat, scaly patch, while squamous cell carcinoma may look like a firm, red nodule or a flat sore that doesn’t heal. Melanoma, the most dangerous form, often presents as an irregularly shaped mole or a change in an existing mole. Early detection is essential, as most cases are highly treatable when caught in their initial stages.
Prevention and Risk Factors
Preventing skin cancer involves several strategies. Limit sun exposure, especially between 10 AM and 4 PM when UV rays are strongest, and always use sunscreen with an adequate SPF. Other preventative measures include wearing protective clothing and regularly checking your skin for any changes in moles or new growths. Risk factors for developing skin cancer include having fair skin, a history of sunburn, or a family history of skin cancer. Regular visits to a dermatologist can also aid in early detection and peace of mind.
