Question: What allows cancer cells to become invasive?

What makes cancer cells invasive?

Invasive tumor growth is enabled by the detachment of malignant cells from the tumor mass due to a reduction in or complete loss of intercellular adhesion molecules, and, therefore, the cells gain the ability of anomalously high motility enabling penetration through the stiff structural elements of the surrounding …

Metastases are formed by cancer cells that have left the primary tumor mass and traveled by the body’s highways—blood and lymphatic vessels— to seek out new sites throughout the body where they may found new colonies.

What is required to enable a cancer cell to metastasize?
