Which statement correctly identifies the most dangerous form of skin cancer?

• A. Malignant melanoma
• B. Basal cell carcinoma
• C. Squamous cell carcinoma
• D. Non-melanoma carcinoma

Answer: (A)

Melanoma is the form of skin cancer with the highest risk to life because it tends to spread quickly to lymph nodes and distant organs. It originates in pigment-producing melanocytes and can arise from a changing mole or a new pigmented lesion, which is why early detection is crucial. The deadly potential of melanoma comes from its ability to metastasize even when the primary tumor is still small, making timely treatment essential. Basal cell carcinoma and squamous cell carcinoma are more common but generally less deadly because they grow more slowly and are less likely to spread to distant sites. Basal cell carcinoma tends to stay local, causing local tissue damage if untreated, while squamous cell carcinoma can metastasize in some cases but far less often than melanoma. The term non-melanoma carcinoma isn’t a standard category and doesn’t carry the same risk profile as melanoma.
