Anti-Angiogenic Drugs are Being Used to Decrease Tumor Growth

Question

Anti-angiogenic drugs are being used to decrease tumor growth. These drugs work by decreasing
A) cell division.
B) cell communication.
C) new blood vessel formation.
D) focal calcification.
E) vascular flow.

Accepted Answer

Anti-angiogenic drugs work by inhibiting the formation of new blood vessels, particularly those that supply the tumor with nutrients and oxygen necessary for cell proliferation and growth. By reducing this blood supply, the tumor's growth is slowed down or stopped. Anti-angiogenic drugs do not directly affect cell division or communication, focal calcification, or vascular flow.
