Final answer:
Angiogenesis is the process of developing tumor vascularization, and it can be inhibited by drugs called angiogenesis inhibitors to prevent tumor growth and spread.
Step-by-step explanation:
Angiogenesis is the process of developing tumor vascularization. It involves the creation of new blood vessels from existing ones. Angiogenesis inhibitors, which are drugs that inhibit this process, can be used in cancer treatment because they help prevent the growth and spread of tumors by blocking the blood supply they need to thrive. These drugs can be used in combination with other treatments to target the blood vessels feeding the tumor.
