Cancer cells undergo a high rate of death due to disordered growth and lack of vasculature, releasing DNA into the bloodstream.

“cancer cells are constantly dying right so you think of cancers as growing very quickly and that's true but they actually um are dying at an incredible rate because it's disordered growth right so many of the cells that divide or you know have all kinds of genomic problems so they die or they're cut off from vasculature so um but the crazy thing about a tumor is yes it's it's growing in you know fast if it's an aggressive tumor but also the amount of cell death um within that tumor is just uh you know is very high”
