Detailed explanation-1: -Invasive cancer is a term that describes cancer that has grown past the original tissue or cells where it developed, and spread to otherwise healthy surrounding tissue. According to the National Cancer Institute, invasive cancer is also called infiltrating cancer.

Detailed explanation-2: -Metastasis. In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor.

Detailed explanation-3: -(in-VAY-siv KAN-ser) Cancer that has spread beyond the layer of tissue in which it developed and is growing into surrounding, healthy tissues.

Detailed explanation-4: -Tissue invasion is the mechanism by which tumor cells expand into nearby environments. Metastasis refers to the process of tumor cells breaking away from the primary tumor, migrating to a new location and establishing a new, or secondary tumor, in the new environment.
