Different way of how tumors spread opens up a new research against cancer

The way that tumor grows and spread is called angiogenesis. For years researchers have focussed on studying the process and developing drugs targeting this mechanism.
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels. It is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer ​[source: Wikipedia]. 
Another way that tumors could use to spread is called vasculogenic mimicry. Until now there was some kind of skepticism about it, but it seems that it is an actual problem and  some treatments are starting to focus on it.
The term vasculogenic mimicry describes the formation of fluid-conducting channels by highly invasive and genetically dysregulated tumor cells  ​[source: APMIS. 2004 Jul-Aug;112(7-8):508-25].
If this process helps metastasis (the migration of tumor cells to new parts of the body), blocking it could save millions of lives every year.
