Screening, diagnosis, and treatment for the three main types of skin cancer.
Squamous cell carcinoma is the second most common skin cancer, often appearing as a firm, red bump, a scaly patch, or a sore that crusts and bleeds. It's more likely than basal cell carcinoma to grow quickly and, in rare cases, spread to other parts of the body if untreated.
Cumulative UV exposure is the primary cause; risk is also elevated by immune suppression, prior radiation, and chronic wounds or scars.
Daily sun protection and prompt treatment of precancerous actinic keratosis, which can progress to squamous cell carcinoma if left untreated.
Surgical excision, Mohs micrographic surgery, radiation, or systemic therapy for advanced cases.
Myth: Squamous cell carcinoma only appears on the face. Fact: It can develop anywhere on the body, including on scars, chronic wounds, and areas that rarely see the sun.
If you notice a firm, scaly, or crusted growth that grows or doesn't heal, especially on sun-exposed skin.
