The green eyed monster

What is cancer? Or more specifically what is Acute Myeloid Leukemia? For most of my life I've viewed cancer as this green eyed ugly monster cell that goes around infecting other cells and causing all sorts of havoc in the victim, but now that view is no longer valid. From what I understand my cancer cells are just cells that are underdeveloped and immature, they are larger than normal cells and tend to reproduce and divide much quicker than healthy cells. They are not malicious, mean and scary as I previously imagined but lazy, fat and immature. They crowd out the normal healthy cells and make it challenging for the normal cells to do their job. Without treatment cancer cells will reproduce too fast for the healthy cells to compete and will spread to the whole body and  within only a few months the body will shut down....but I am a lucky one and the green eyed monster was discovered quite early so there is much hope that given enough chemo the cancer will go into remission. And so begins the Chemo. :)
