What is the most deadly form of skin cancer?

1. Basal cell carcinoma

2. Squamous cell carcinoma

3. Malignant melanoma

4. Keratoacanthoma

The correct answer is: Malignant melanoma

Malignant melanoma is regarded as the most deadly form of skin cancer due to its aggressive nature and potential to metastasize, or spread, to other parts of the body if not detected and treated early. Unlike basal cell carcinoma and squamous cell carcinoma, which are more common but typically localized and less likely to result in serious health consequences, malignant melanoma can develop from existing moles or appear as new dark spots on the skin. It often spreads rapidly to lymph nodes and other organs, leading to a greater risk of mortality. Keratoacanthoma, while it can appear similar to squamous cell carcinoma, is generally considered a less aggressive tumor and often resolves on its own. Therefore, when considering the serious implications of skin cancer, malignant melanoma clearly stands out as the most dangerous type, highlighting the importance of early detection and monitoring of skin changes.
