C44.310

Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds Fair skin that burns easily and does not tan well Older age, since BCC is more common in individuals over 50 History of frequent sunburns during childhood or adolescence Presence of previous skin cancers or precancerous skin lesions Exposure to certain environmental toxins or radiation Genetic predisposition or family history of skin cancer

Key Symptoms: A shiny, pearly, or translucent bump on the skin A sore or crater that persists and does not heal Pink, red, or brown patches that are slightly raised Waxy scars or scars that look like scars from healing wounds Rolled edges around a pearly bump Itching, bleeding, or crusting in the affected area Changes in the appearance of a mole or skin growth

Diagnosis Path: Diagnosis of basal cell carcinoma often involves a physical skin examination where the healthcare provider checks for characteristic signs of BCC. A biopsy is typically performed, during which a small sample of the suspicious skin is removed and examined microscopically. Additional imaging tests may be used if the tumor appears to have invaded deeper tissues or if there is concern about spread, although this is uncommon with BCC. Accurate diagnosis is essential to determine the appropriate treatment plan.

Treatment Protocols: Treatment options depend on the size, location, and type of BCC, as well as the overall health of the patient. Common approaches include: - Surgical excision, where the cancerous tissue is cut out and the wound is closed with sutures - Mohs surgery, a precise surgical technique that removes cancer layer by layer, conserving healthy tissue - Cryotherapy, which involves freezing and destroying cancer cells - Topical treatments such as creams or ointments containing 5-fluorouracil or imiquimod - Radiation therapy for cases where surgery is not feasible - Laser therapy or photodynamic therapy in select cases Early diagnosis and treatment are key to preventing further skin damage and the potential for scarring or disfigurement.
