Humans have been practicing selective breeding ever since there were humans.

Really? How so? Drowning the unwanted, like they do with kittens or puppies?

You might just as well lament the fact that the several million of Chloe's father's sperm all swam to no end and died.

Only one sperm can impregnate an ovum! It takes millions of sperm for the one to reach its destiny. Your argument makes absolutely no sense.

And I suspect this child will be very thankful to her parents that she will not have to spend the first few decades of her life knowing that she will eventually die of cancer at a young age.

And how will she know this if the parents have not pointed this out to her, which you attest will never happen.

Nope, just by deciding with whom one wants to reproduce. In human populations, individuals tend to reproduce with more fit members. That's the very definition of selective breeding. For example, many men would chose to breed with Heidi Klum, but few with Helen Thomas.

Let me explain it to you again. If you lament the millions and millions of embryos that naturally die every year (which I doubt you do), you might as well lament the millions and millions of sperm which also do not fertilise an egg. They are both largely irrelevant and morally inconsequential, or neither are.

And I suspect this child will be very thankful to her parents that she will not have to spend the first few decades of her life knowing that she will eventually die of cancer at a young age.

And how will she know this if the parents have not pointed this out to her, which you attest will never happen.

Strike the "to her parents" phrase: I supsect the child will be very thankful that she will not have to spend the first few decades of her life knowing that she will eventually die of cancer at a young age.
