I still don’t understand HOW cancer kills.
I mean, we just have some additional cells who does not perform their normal functionality. But we still have a big bunch of normal, functioning cells.
In my (very very) distant family, someone died from lung cancer a few months ago. I still don’t understand the link between the few additional cells in his lungs and the acute hepatic failure that killed him.
I read somewhere that a primary cancer seldom kills ; most of the time the metastasic-induced does. Why ? There should be far more "bad" cells in the primary site, doesn’t it ?
(medecine illiterate there, sorry if half of my assumptions are wrong)
To throw another reference into the discussion, section 1.8 of McKinnell et al.'s The Biological Basis of Cancer spends a few pages on this. Summary: cancers can cause organ failure, but because the body has "an enormous reserve of normal tissue plus a built-in mechanism to regenerate more" organ failure is not usually the proximate cause of (edit: non-leukaemia) cancer death; the most common cause of death is instead cachexia (wasting) and hence infection.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
