Did death evolve?

Discussion of the distribution and abundance of living organisms and how these properties are affected by interactions between the organisms and their environment

cancer cells are immortal but they do harm to their hosts. (I could't find another word instead of host). I mean, when you have cancer, (a malign one) sooner or later it will do harm to your body and lead the body to death.

I agree with Kyle,
It doesn't matter how healthy you live (like not smoking or such kind of things) one day ,(usually after a certain age) you will have cancer...

So cancer is our way to limit life, which relies on DNA mutations. Perhaps at one stage DNA did not mutate,however it evolved to do so, thus leading to a limit on life.

not all organisms have it in their genes for programmed death, most do.

So what organisms do not have programmed death?

Cancer is ONE way we limit life. Let me get in contact with Dr. Blem and I'll ask him for an example. One is a bird....but can't remember which one.

How can cancer cells be immortal if they get divided, division = death here, as in bacts???

And see if cancer is one of the ways of getting deaqd after some years we would be able to stop all types of cancer and thus get nearer to immortality.

hey, I think you should get some info about cancer.

If we stop all types of cancer (and I don't think this is likely to happen), maybe we can live longer.

Actually poison, i've switched my essay topic to cover cancer somewhat, specifically I'm discussing how internal cancer risks(colon in my case) would differ from external cancer(skin) as age progresses. Any info you could pm me with would be greatly appreciated :D.

yes. cancer cells are immortal, unless you kill them or unless the cancer cells kill their host. the cells are immortal but as they spread (metastasis) they harm the body. Because cancer cells are not identical to normal cells. they are different. and note that it is an uncontrolled division. the cells divide continuously. normal cells divide to a point and then stop. the mechanism that stops them is called contact inhibition.
cancer cells kill their hosts. (or you can call it the body.) when cancer spreads to some organs it causes many activities to stop and finally the person dies. When the person (or it might be more logical to call organism instead of person) dies all metabolic activities stop as well.
so doesn't that mean the death of cancer cells too?

@mithrilhack
I will try to find some info. but if you give me more details about what the subject exactly is, it will be easier. Feel free to pm me.

Cancer cells only stop dividing after the death of the patient. This is due to the lack of incoming sustenance; proteins, carbohydrates, and especially lipids. Cells need these to divide. Without them, cells will die.

Thats right Kyle. that is what i was trying to say. :) when the patient dies, the cells die too. but if make a culture of cancer cells , they won't die as long as you provide optimum conditions.

Wohoo! I know something after all! lol

So is death a biological response to kill the cancer cells?
