Molecular interactions of cancer and age

The authors believe that the aging process--the loss of youthful resilience--is caused by the decline of many hormones. By restoring these hormone levels, the decay associated with old age can be eliminated and in some cases, perhaps reversed. The hormones that naturally occur in the body should be replenished through a medically sound regimen. The hormones must work together. The data indicate that aging occurs at two levels: systemically and cellularly. Systemic controls regulate the rates of intracellular enzymatic processes that accelerate to protect against aging.
