How Tumors Grow

You probably never want to hear that you have a tumor, and much less that it has metastasized. Learning how tumors grow and manage to combat therapeutic approaches is interesting on its own right, but it can also have the added benefit of revealing ways to beat the hijacking little bastards and save countless lives. In today's beautiful animation, you can get a crash course on tumors for your oncology class :)

I take it cutting the blood vessels feeding the tumors is not very practical?
