Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from sunlight or tanning beds History of skin damage from sunburns or repeated injury Fair skin, light hair, and light eyes increase susceptibility Weakened immune system due to medical conditions or medications Exposure to carcinogenic chemicals or substances Personal or family history of skin cancer Age-related skin changes and cumulative sun exposure over the years

Key Symptoms: Appearance of a new, persistent skin lesion or sore that does not heal Rough, scaly patches on the skin that may bleed or ooze Unusual growths or nodules on the face Changes in size, shape, or color of existing moles or lesions Persistent redness or inflammation in a specific area of the face Skin ulcers or lesions that enlarge over time Difficulty or pain in the affected area (less common)

Diagnosis Path: Diagnosis typically involves a combination of clinical examination and biopsy. During a physical exam, a dermatologist will inspect the skin for abnormal changes. A biopsy involves removing a small tissue sample from the suspicious lesion, which is then examined under a microscope to confirm the presence of malignant cells. Additional tests, such as imaging scans, might be performed to determine the extent of the spread if necessary. Accurate diagnosis is essential to determine the most effective treatment plan.

Treatment Protocols: Treatment options depend on the size, location, and extent of the cancer. Common approaches include: - Surgical excision: Removing the cancerous tissue with a margin of normal skin. - Mohs surgery: A precise surgical technique that removes the cancer layer by layer, conserving as much healthy tissue as possible. - Radiation therapy: Using targeted radiation to destroy cancer cells, often used when surgery isn't suitable. - Topical treatments: Such as creams or ointments containing anti-cancer agents, more common for early or superficial lesions. - Systemic therapies: Including chemotherapy, targeted therapy, or immunotherapy for advanced cases. Follow-up care involves regular skin checks to monitor for recurrence or new lesions. Early detection and prompt treatment significantly improve prognosis in skin cancers.
