RE: NCRP 136 / Immunology, DNA repair, cancer...

["Jacobus, John (OD/ORS)" <jacobusj@ors.od.nih.gov>]

Les, 

I think you are a little confused as to how cancers develop, and what role

the immune system and cellular components play in DNA repair.  If cancer

initiation, development and propagation were as simple as you think, we

would have found cures years ago.



I would recommend you read the Mossman article, and let me know what you

think.

The Mayo Clinic (internet site) says:



"Although the DNA controls the cell division process, the body's immune

system serves as a quality controller; under normal circumstances the immune

system regulates the orderly and predictable dividing of cells. If cells

begin to divide too quickly, for instance, "scavengers" or "soldiers" in the

bloodstream physically devour the abnormal cells and prevent them from

causing illness.



If an immune system is weakened because of exposure to certain chemicals or

disease, cancer is more prevalent."



It would seem the immune response goes after the defective cells themselves.



Not being a cancer expert, that's just the way I read what Mayo Clinic said.

(and I've been reading a lot of similar stuff for the 3 years my wife has

been undergoing chemotherapy for her cancer).

>I never realized that "cancer is determined by how the body is able to

defend itself." So, I guess the 25% of the population that get cancer have 

defective immune systems.

---

In order for the immune system to function on a cellular level there must be



antigens that the immune system can react against. 



Therefore, I don't think that the immunology has any important role in the 

protection against cancer.



My personal opinion,
