What is natural selection?

Question

If a healthy female was impregnated by cancerous male would evoloution or natural selection correct the problem and are we interfering with evoloution by not totally relying on it to correct our health woes?

Answer 1

If a "cancerous male" has already impregnated a "healthy female" then there isn't too much selective pressure left. In some sense we're always "interfering" with evolution but in another sense how can we?!

Answer 2

If a genetically determined cancerous male impregnates a healthy female , it results in natural selection by a blighted ovum that gets aborted early , a child developing cancer earlier than father, a child who would develop cancer later in adulthood, or a non cancerous child
If a genetically undetermined cancerous male impregnates a healthy female normal pregnancy results.
Natural selection is a continuous process not confined to a single generation or pregnancy.

Answer 3

It would have no effect on the fetus or the mother.
Cancer is not spread through to others DNA.
It is contained within our own, it would not be passed to the child. Natural selection is a process of adaptation to determine the stronger species from that of the weaker ones. Those that are strong, adapt to surrounding changes, while those who do not perish. Cancer does not show a weakness, it is a mix of factors, environmental, genetic, and the Mitotically active cells within our body that from time to time make a mistake while encoding from DNA and form an ineffective cancerous cell that is not destroyed by our own immunities.
