Which statement describes unresectable melanoma?

• A. It cannot be reached by surgery
• B. It spreads to distant sites
• C. It is benign
• D. It is curable with antibiotics

Answer: (B)

Unresectable melanoma means the cancer cannot be removed completely by surgery. The defining issue is that the disease has spread beyond the original site in a way that no operation can remove all cancerous tissue and achieve cure. When melanoma has metastasized to distant sites, surgery alone cannot eradicate the systemic disease, so it’s considered unresectable.

The other statements don’t fit as the best description: simple inaccessibility to surgery can render a tumor unresectable, but the hallmark exam-wise is metastasis to distant sites indicating spread. Melanoma is malignant, not benign, and antibiotics don’t cure cancer.
