Which type of non-melanoma skin cancer is known to be more aggressive?

Squamous Cell Carcinomas (SCC) are generally considered to be more aggressive compared to Basal Cell Carcinomas (BCC). SCC can invade deeper layers of the skin and have a higher likelihood of metastasizing, meaning they can spread to other parts of the body. This characteristic makes squamous cell carcinoma more concerning in terms of potential complications and the need for prompt treatment.

Basal cell carcinomas, while they can grow locally and cause significant local damage, rarely metastasize and are often referred to as "non-aggressive" cancers. They tend to be more manageable and are associated with a lower risk of serious health issues.

Thus, identifying SCC as the more aggressive type recognizes the need for increased vigilance and treatment strategies that may be required to address its potentially harmful progression.
