Apparently
immunotherapy does not work very well as a weapon against ovarian cancer. According to this article, emerging from
research performed at the Wistar Institute, a prominent biomedical facility
located in Philadelphia, this is because OVCA protects itself against the
immune system by means of the activities of several rogue genes, which the
Wistar people identify. It is hoped that
this discovery will lead to more effective therapies.
To me, it is
a puzzle how genetic defects like these can avoid being eliminated from the
gene pool by normal evolutionary processes.
After all, to my perhaps primitive way of thinking evolution will
preserve and propagate mutations that confer a survival advantage. How can a genetic change that contributes to
the death of its host be beneficial?
Maybe these genes help get a woman past puberty and reproduction age, and
then go bad? Beats me. But I am thankful for the scientists who come
up with these facts and conundrums. We
will beat the SOB yet!
