one problem with Cancer is if person get it in the age there are not longer able having offspring nature selection is powerless to reduce the frequency of that disease in population
Yes and no, you see natural selection may not be able to directly influence a person past breeding age but there are a host of other factors, if a person dies after having children then presuming the child is still young they will be unable to care for that child. Human also chose their mates (partly) based on health and family health, allowing for a form a disjointed sexual selection. On another note cells also have a massive shortterm advantage 2wards cancer and cancers themselves can evolve.
