yes i know what its for...it helps kill cancer cells but it also kills good cells as well which is why sometimes hair loss happens...

but i want a more in depth definition...like what causes the nausea? && why do cancer patients have to go through so many rounds of it?? i am very interested in cancer, as lots of people in my family have had it...i always feel so sad when i think of the people suffering from it and chemo therapy almost seems worse than the cancer itself!

anybody ever undergo chemo?
