Skin Cancer

Skin cancer is a prevalent malignancy characterized by the abnormal growth of skin cells, often triggered by excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds. The most common types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma typically appears as a pearly or waxy bump and tends to grow slowly, while squamous cell carcinoma often manifests as a red, scaly patch or a sore that fails to heal. Melanoma is the most aggressive form, arising from melanocytes, the pigment-producing cells, and can appear as a changing mole with irregular borders and varying colors. Early detection and treatment are crucial, with surgical excision being the primary approach for removing cancerous lesions. In some cases, other treatment modalities such as radiation therapy, immunotherapy, or targeted therapy may be employed, depending on the stage and type of skin cancer, emphasizing the importance of sun protection and regular skin examinations to prevent and detect skin cancer at its earliest, most treatable stage
