How Does Angiogenesis Contribute to Cancer Growth?
Angiogenesis is a natural process in the body, essential for wound healing and the formation of the placenta during pregnancy. However, in cancer, this process is hijacked to support tumor growth. Tumors release angiogenic factors like vascular endothelial growth factor (VEGF) to stimulate the formation of new blood vessels. These new vessels not only supply the tumor with nutrients and oxygen but also provide a pathway for cancer cells to enter the bloodstream and metastasize to other organs.
