Which diagnosis is a fast-growing cancer of the skin?

• A. Basal cell carcinoma
• B. Melanoma
• C. Squamous cell carcinoma
• D. Lichen planus

Answer: (B)

Growth and spread patterns among skin cancers vary a lot, and melanoma is the one that stands out for rapid expansion and earlier spread. Melanoma arises from pigment-producing melanocytes and can grow quickly, especially in its vertical phase, meaning it can invade deeper into the skin and reach lymph nodes or distant sites sooner than other skin cancers. This aggressive behavior is what makes melanoma the fast-growing cancer of the skin. Basal cell carcinoma typically progresses slowly and rarely spreads beyond the local area, focusing on local tissue destruction rather than rapid growth or metastasis. Squamous cell carcinoma can be more aggressive than basal cell and may metastasize in some cases, but overall it doesn’t usually exhibit the same rapid, widespread growth pattern as melanoma. Lichen planus is not cancer at all; it’s an inflammatory condition that can affect the skin or mucous membranes. So, melanoma is the best answer because its growth and potential to metastasize happen more rapidly than the other options.
