C44.91

Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun Use of tanning beds and artificial tanning devices Fair skin that burns easily and doesn't tan well A history of frequent sunburns or outdoor work Certain genetic conditions that increase skin cancer risk Immunosuppression due to medical treatments or health conditions

Key Symptoms: Appearance of a pearly or translucent bump on the skin New sore that doesn’t heal, or a sore that heals and then reopens Pink, scar-like area without a clear border Waxy or shiny growths on the skin Lesions that bleed easily or develop a crust Scar-like area that may feel raised or rough

Diagnosis Path: Diagnosis typically involves a thorough skin examination by a healthcare professional. They may perform a biopsy, removing a small sample of tissue from the suspicious lesion, which is then examined under a microscope to confirm the presence of basal cell carcinoma. Additional imaging tests might be employed if the cancer appears to have spread or to assess the extent of the lesion. Proper diagnosis is key to determining the most effective treatment plan.

Treatment Protocols: Treatment options for basal cell carcinoma depend on the size, location, and depth of the lesion. Common approaches include: - **Surgical excision:** Removing the cancerous tissue along with a margin of healthy skin. - **Mohs micrographic surgery:** A precise technique that removes the cancer layer by layer, examining each layer under a microscope until no abnormal cells remain. - **Curettage and electrodessication:** Scraping away the lesion and using electrical current to destroy residual cancer cells. - **Topical medications:** Such as imiquimod or 5-fluorouracil, often used for superficial BCC. - **Radiation therapy:** Used in cases where surgery isn’t feasible. Early detection and treatment help prevent the cancer from spreading or causing significant tissue damage.
