Final answer:
Squamous Cell Carcinoma (SCC) is generally more aggressive and has a higher potential for metastasis than Basal Cell Carcinoma (BCC), which grows more slowly and is less likely to spread.
Step-by-step explanation:
When comparing which type of skin cancer grows more quickly or is more aggressive between Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC), SCC is generally considered to be more aggressive. BCC typically grows at a slower rate and is less likely to spread to other parts of the body (metastasis), while SCC has a greater potential for metastasis if not treated early.
SCC can also recur and can become invasive more frequently than BCC. Treatment for both includes surgical removal, but due to its higher aggressiveness, SCC may require additional treatments such as radiation therapy or chemotherapy.
