WebLike healthy cells, cancer cells can't live without oxygen and nutrients. So they send out signals called angiogenic factors. These encourage new blood vessels to grow into the tumour. This is called angiogenesis. Without a blood supply, a tumour can't grow much bigger than a pin head. http://web.mit.edu/hst527/www/readings/Lecture%2024/Cancer%20Med%20Final%20from%20C%5B2%5D.pdf
