C44.70

Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds Genetic predisposition or family history of skin cancer History of skin injuries or scars that did not heal properly Exposure to carcinogenic substances, such as arsenic or certain chemicals Weakened immune system due to illness or medication Presence of atypical or precancerous skin lesions that may develop into malignancies Older age, as risk increases with age

Key Symptoms: A new or changing skin lesion, often appearing as a sore that doesn't heal A raised, firm, or nodular growth on the skin surface Lesions with irregular borders, asymmetry, or uneven coloration Persistent pain, bleeding, or itching at the site of the lesion Ulceration or oozing from the affected skin area Lumps or swelling in or near the affected region Skin changes, such as thickening or a scar-like appearance

Diagnosis Path: Diagnosis typically involves a thorough physical examination of the skin and affected area, followed by biopsy to confirm the presence of malignant cells. Additional diagnostic tools may include histopathological analysis, imaging studies like ultrasound, MRI, or CT scans to assess the extent of involvement, and lymph node evaluation to check for spread. Because the specific type of skin cancer is unspecified, further testing might be needed to clarify the diagnosis and plan appropriate treatment.

Treatment Protocols: Treatment strategies depend on the size, location, and spread of the neoplasm, as well as the patient's overall health. Common options include: - Surgical excision to remove the tumor and surrounding tissue, aiming for complete removal - Mohs micrographic surgery, especially for tumors in cosmetically or functionally sensitive areas - Radiation therapy to target residual cancer cells - Systemic therapies such as immunotherapy or chemotherapy in advanced cases - Follow-up monitoring to detect any recurrence or spread Consulting healthcare professionals specializing in dermatology or oncologic surgery is essential for personalized treatment planning.
