Clinical Causes: Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds History of frequent sunburns or excessive sun exposure Immunosuppressive therapy or conditions that weaken the immune system Previous skin injuries, burns, or scars that may have been exposed to UV light Exposure to certain chemicals or carcinogens Inherited genetic predispositions to skin cancer Age, with higher incidence in older adults

Key Symptoms: A persistent, scaly, or crusted patch on the skin A sore that does not heal or repeatedly heals and reopens Raised, firm growth with a surface that may be ulcerated or keratinized An open sore or wart-like growth that may bleed or crust Changes in the appearance of the skin, such as color or texture variations Tenderness, pain, or itching in the affected area

Diagnosis Path: Diagnosis typically involves a physical examination by a healthcare provider, who assesses the skin lesion's appearance. If a suspicious lesion is identified, a biopsy is performed to confirm the presence of squamous cell carcinoma. Additional diagnostic tests may include imaging studies if there is concern about local spread or metastasis, especially in advanced cases.

Treatment Protocols: Treatment options depend on the size, location, and stage of the cancer, and may include: - Surgical removal of the tumor, often through procedures like excision or Mohs surgery - Radiation therapy to target cancer cells while sparing surrounding healthy tissue - Topical medications or cryotherapy in early or superficial cases - Systemic therapies such as immunotherapy or chemotherapy for more advanced or metastatic cancer Careful follow-up and regular skin examinations are important to monitor for recurrence or new cancers. Prevention strategies include minimizing UV exposure and using protective clothing and sunscreens.
