Which type of skin cancer is the most fatal yet least common?

Malignant melanoma is considered the most fatal yet least common type of skin cancer due to its aggressive nature and ability to spread rapidly to other parts of the body, including vital organs. While it accounts for a smaller percentage of skin cancer cases compared to basal cell carcinoma and squamous cell carcinoma, its potential for metastasis makes it particularly dangerous. Early detection and treatment are crucial, as the prognosis worsens significantly once the cancer spreads beyond the skin. This contrasts with other types of skin cancer, which, while more prevalent, tend to be less aggressive and have higher cure rates when detected early.
