Invasion and Metastasis of Carcinomas
The hallmark of a malignant tumor is its tendency to invade and infiltrate local and adjacent structures and, eventually, spread from the site of its origin to non-adjacent regional and distant sites in the body, a process called metastasis. If unchecked, tumor growth and metastasis eventually creates a tumor burden so great that the host succumbs. Carcinoma metastasizes through both the lymph nodes and the blood.

Famous quotes containing the word invasion:
“In our governments the real power lies in the majority of the community, and the invasion of private rights is chiefly to be apprehended, not from the acts of government contrary to the sense of the constituents, but from the acts in which government is the mere instrument of the majority.”
—James Madison (1751–1836)
