This segment shows how Dr. Judah Folkman gained his insight of angiogenesis, and how the biological field disagreed the existence of angiogenesis. This is Part 2 of a 8 part series (http://www.pbs.org/wgbh/nova/cancer/program.html) that introduces a possible non-toxic cancer treatment and highlights the long journey of how angiogenesis (new blood vessel growth) was discovered, how most...

This segment illustrates how Dr. Judah Folkman designed experiments to provide solid proof of angiogenesis' existence, and the further identification of angiogenesis factors. The identification of angiogenesis factors was so time consuming (it took several years of effort) that even Dr. Folkman doubt whether this factor existed. The quote from Dr. Folkman: "In research, there's a very fine line...

This segment shows how angiogenesis inhibitors, potential cancer treatment, were identified. Is it identified through good luck, through hard work, or through something else? This is Part 4 of a 8 part series (http://www.pbs.org/wgbh/nova/cancer/program.html) that introduces a possible non-toxic cancer treatment and highlights the long journey of how angiogenesis (new blood vessel...

This segment shows the other approach of searching and identifying angiogenesis inhibitors. This is Part 5 of a 8 part series (http://www.pbs.org/wgbh/nova/cancer/program.html) that introduces a possible non-toxic cancer treatment and highlights the long journey of how angiogenesis (new blood vessel growth) was discovered, how most scientists thought angiogenesis as ridiculous, how...

This segment demonstrates how cancer spreads through a mechanism called metastases, and how the puzzle of metastases inspired Dr. Folkman to identify more angiogenesis inhibitors. This is Part 6 of a 8 part series (http://www.pbs.org/wgbh/nova/cancer/program.html) that introduces a possible non-toxic cancer treatment and highlights the long journey of how angiogenesis (new blood vessel...
