Ted,

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.  Are you proposing that we all receive additional

radiation to prevent cancer?  How much would you suggest?  Have you gotten

your dose today?  Do you practice what you preach?

That is simply untrue.  In the presence of millions of metabolism-induced

mutations, the few additional radiation-induced mutations have negligible

effect.  Whether you get cancer is determined by how effectively the body's

defenses work.  When the radiation stimulates these defenses, it reduces not

only the number of radiation-induced mutations but also the much larger

number of metabolism-induced mutations.
