> there’s little survival advantage for people who can effectively fight cancer after their reproductive age While there's less evolutionary advantage, it's far from trivial. See, for instance, https://www.pnas.org/content/100/16/9637 https://www.pnas.org/content/100/16/9637 : > In some species, postreproductive females make substantial contributions to their descendants, either through direct parental care or through grandparental care. Such contributions continue after birth in all mammals (most notably primates), all birds, many insects, and some fish (15). Postreproductive bottle-nose dolphins and pilot whales baby-sit, guard, and even breastfeed their grand-children (15). Selection against the mortality of postreproductive individuals in such species would be expected to continue.
