Angiogenesis is the process by which new blood vessels form within the body. In cancer, factors can be released that promote the formation of blood vessels in and around a tumor, supplying it with its own blood supply. The presence of these blood vessels is often correlated with a poor prognosis in patients with cancer. This medical animation describes the structure of these new blood vessels and some of the issues associated with tumor angiogenesis.
This animation forms part of a larger web based project that Random42 developed to increase the awareness of cancer driven angiogenesis. This can be viewed here.
