Angiogenesis contributes to cancer development by A. inhibiting apoptosis (programmed cell death). B. providing nutrients and ox
ygen to tumors and by facilitating metastasis. C. preventing the normal inhibition of growth that occurs when cells make contact. D. initiating a mutation in a gene that causes uncontrolled cell growth.
B, providing nutrients and oxygen to tumors and by facilitating metastasis
Explanation:
Tumor angiogenesis refers to the formation of nascent vasculature during tumor progression, enabling delivery of nutrients and oxygen as well as the removal of waste. Angiogenesis facilitates metastasis by enabling transport of tumor cells to distant sites via vascular and lymph systems.
