Cancer as a chaotic adaptation of the adult stem cell.
Tez M, Koç M, Bilgin A.

I don’t specifically know how it kills people, but such a process has obvious negative consequences.

I think medicine has lost sight of the fact that people who “die of caner” really die of systemic burdens imposed by pathogen proliferation.

Oncologists focus on “reducing tumor burden” but never tell the patient that reducing the size or number of his tumors does not necessarily extend his life one bit.

Perhaps the best place that explains cancer without over-simplifying is Arny Glazier’s book.

In my current understanding, there is an element of all three of the alternatives, and many other factors as well in terms of what kills you about cancer. In some ways it’s better to ask, how does normal multicellular life work and sustain itself? At the highest level of abstraction, I view cancer as the autocatalytic unwinding — or the photo negative — of multicellular life.
