Verified step by step guidance

Understand the concept of angiogenesis: Angiogenesis is the process through which new blood vessels form from pre-existing vessels. This is a normal and vital process in growth and development, as well as in wound healing.

Consider the role of angiogenesis in cancer: In the context of cancer, angiogenesis is crucial because it allows tumors to grow beyond a small size by providing them with the necessary blood supply to receive oxygen and nutrients.

Evaluate the options given: Analyze each option to determine which one aligns with the role of angiogenesis in cancer. The options are: stimulating growth factors, providing a blood supply, blocking apoptosis, and increasing DNA replication.

Identify the correct function: Recognize that the primary role of angiogenesis in cancer is to provide a blood supply to the tumor cells, which is essential for their growth and survival.

Conclude with the correct answer: Based on the understanding of angiogenesis, conclude that the correct answer is that it provides a blood supply to the tumor cells, enabling them to grow and potentially metastasize.
