Verified step by step guidance

Understand the concept of angiogenesis: Angiogenesis is the process through which new blood vessels form from pre-existing vessels. Tumors often stimulate angiogenesis to supply themselves with the necessary nutrients and oxygen for growth.

Identify the role of anti-angiogenic drugs: These drugs are designed to inhibit the process of angiogenesis, thereby cutting off the blood supply to the tumor, which can lead to the starvation and death of cancer cells.

Differentiate between the therapies: Chemotherapy targets rapidly dividing cells, surgery physically removes tumors, and passive immunotherapy uses antibodies to target cancer cells. None of these directly target blood vessel formation.

Recognize the specific action of anti-angiogenic drugs: Unlike other therapies, anti-angiogenic drugs specifically aim to destroy the blood vessels that support tumor growth, making them unique in their approach.

Conclude that anti-angiogenic drugs are the therapy that targets cancer cells by destroying the blood vessels that support tumor growth, distinguishing them from other treatment options.
