To illustrate potential mutation - specific
effects on absolute cancer risks, we used the hazard ratio estimates to derive approximate absolute risks and 95 % confidence intervals, based on published estimates for the overall risks
of breast and ovarian cancer by
age 70 years.26 These estimates are for illustration and do not represent absolute risk estimates that would be required in a
genetic counseling setting, as they do not account for noncancer outcomes that may influence a woman's life expectancy, the
effects of family history, and nonrandom ascertainment
of mutation carriers in this sample and depend on assumptions about the prevalence
of different mutation classes in the population.

One theory is that
aging is caused by the cumulative
effects of random
genetic mistakes — distortions in the
genetic code that take place as cells reproduce billions

of reasons — certain
genetic mutations, exposure to radiation and most importantly health and lifestyle choices — but the resulting

aging.
ACE Pro Jonathan Ross tackles this
age - old question, comparing
