There's an important protein called VEGF, which stands for vascular endothelial growth factor. This protein plays a crucial role in the formation of new blood vessels, a process known as angiogenesis.

A high VEGF level may indicate a weakness in your blood vessels, leading to the excessive growth of new blood vessels.
