yes they do. However majority of Americans want something to make them feel better. Some things like virus you cant"cure" your body has to do it. So you treat the symptoms. I am not a med student but a General physiology, immno class or parasitilogy class DOES teach you this.
Commercials for those who think they can solve their own problems by watching TV. So no comment on them, i just wish they would go away
First off...have you or any one close to you had cancer....
This is the most ridiculous statement in this whole thread. Chemo and radiation DO attack the problem not the symptoms. NOW if you mean attack what caused the cancer. The majority of the time we dont know what caused it and never will. In general you need two exposures to carcinagens...one gets your cells weaken by "attacking" a repair mechanism and then one institutes uncontrolled cell growth ( ie cancer). It could be the same chemical or it could be genetic. Some "defective" genes allow for uncontrolled cell growth due to the repair system being damaged/defective. cancer treatments do also treat the symptoms...like nausa from the medicine or being immno-suppressant. They go hand in hand in some cases.
/I wish people would post their ages so we can see what sort of life experience we are dealing with. Some of you post from a very narrow world view that I wonder if its caused by being a young poster who has no experience to base their opinions on.
