Which of these tumors is known for its invasive nature and metastatic potential?

Malignant melanoma is the tumor that is well-documented for its aggressive and invasive characteristics, along with a significant potential for metastasis. Unlike basal cell carcinoma and superficial carcinoma, which are generally less aggressive and have a lower likelihood of spreading to other parts of the body, malignant melanoma can rapidly invade surrounding tissues and spread to distant organs through the bloodstream or lymphatic system.

Squamous cell carcinoma, while it can be invasive, often behaves less aggressively compared to malignant melanoma and is usually localized in its early stages. Basal cell carcinoma is typically the least invasive and is known for its slow growth, rarely spreading beyond the original site. Therefore, malignant melanoma is distinct in its capacity for both invasion and metastasis, making it a crucial focus in oncology due to its serious implications for patient health.
