The "angiogenesis" drug That's what it would be called if we, the average person, were in charge of naming drugs. Angiogenesis is the process of forming new blood vessels in our body. It is mainly needed for regeneration. New tissues need an active blood supply for growth. Yet malignant tumors also need it - they activate the process of angioneesis, due to which they grow at lightning speed. And the drug capecitabine blocks the enzyme, which triggers this mechanism and thus - does not allow the tumor to grow👌🏻
