What is the meaning of anti-angiogenic agents?

Anti-angiogenic agents are drugs that inhibit the formation of new blood vessels (angiogenesis) from existing ones. This process is crucial for tumor growth and metastasis, as tumors require a blood supply to receive nutrients and oxygen. By blocking angiogenesis, these agents can effectively starve tumors and limit their growth, making them an important strategy in cancer treatment. They are also being studied for potential use in other conditions characterized by abnormal blood vessel growth, such as certain eye diseases.
