(A)For the past two years, I have been studying cancer survivors at the university,
trying to find out why it is that some people respond much better to
their treatment than do others.
(B)Some patients fared much better in their therapies than others.
(C)The patients I am talking about here received upon diagnosis whatever therapy -
medication, radiation, surgery - their individual cases demanded.
(D)On closer scrutiny, however, I discovered that severity of the illness was only
one of a number of factors that accounted for the difference between those who
get well and those who don't it.
(E)Yet the response to such treatment was hardly uniform.
(F)At first I thought that some patients did well because their illness were
not as severe as the illness of others.
