Which treatment is typically NOT used for large basal cell carcinoma on the face?

• A. Electrodesiccation and curettage
• B. Surgical excision
• C. Mohs micro surgery
• D. Radiation therapy

Answer: (A)

Electrodesiccation and curettage is not typically used for large basal cell carcinoma on the face due to its potential limitations in completely removing larger lesions. This technique involves scraping away the cancerous tissue and using electrical current to destroy any remaining cancer cells. While it can be effective for small, superficial basal cell carcinomas, it has a higher risk of incomplete removal and recurrence when applied to larger tumors. Therefore, larger basal cell carcinomas necessitate more definitive treatments to ensure total excision and minimize the likelihood of recurrence.

In contrast, surgical excision is a common and effective treatment for larger basal cell carcinomas, as it involves removing the tumor along with a margin of healthy tissue, which decreases the chance of leaving cancerous cells behind. Mohs micro surgery is also ideal for facial tumors because it allows for real-time examination of the excised margins to ensure complete removal. Radiation therapy is sometimes considered for patients who cannot undergo surgery or for those with extensive local disease; however, it is typically not the first-line treatment for large basal cell carcinomas when surgical options are viable.
