Which statement correctly differentiates basal cell carcinoma from squamous cell carcinoma?

• A. Basal Cell Carcinoma grows slowly with rare metastasis; Squamous Cell Carcinoma grows more quickly and can metastasize
• B. Basal Cell Carcinoma is slow-growing with rare metastasis; Squamous Cell Carcinoma is faster-growing and metastatic
• C. Basal Cell Carcinoma is always aggressive
• D. Basal Cell Carcinoma metastasizes more often than Squamous Cell Carcinoma

Answer: (D)

Understanding how basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) differ in behavior is key. BCC tends to grow slowly and almost never spreads beyond the local area. SCC, while often treatable when caught early, can grow more rapidly and has a real risk of metastasis, especially in larger, deeper, poorly differentiated tumors, or in patients with immunosuppression. So the correct differentiation is that BCC is slow-growing with rare metastasis, whereas SCC is faster-growing and can metastasize. The statement that BCC metastasizes more often than SCC doesn't match these patterns; metastasis from BCC is rare, while SCC has a higher metastatic potential in appropriate cases. Clinically, this distinction influences management: BCC is typically treated with local excision or Mohs surgery with very high cure rates, while SCC may require wider margins and assessment for lymph node involvement depending on risk factors.
