Cooking in general affects the nutritional value of food—some nutrients are easier to absorb when cooked, so cooking effectively increases their amount, while other nutrients are destroyed [0] [1]. But given that you're probably cooking your food anyways, there's nothing specific to microwaves here.
Microwaves might actually be slightly better than other cooking methods here, since they produce a lower heat that's less likely to destroy nutrients, but the cooking method has such a minor effect that I wouldn't really worry about it either way.

Microwaves are classified as non-ionizing radiation [2], so their main effect is just heating things up. So if you're standing near a microwave and your body starts heating up, then something bad is happening; otherwise, you're probably fine.
The only health risk from microwaves (aside from a hypothetical accident involving someone being cooked inside one like a rotisserie chicken) is cataracts [3]. But this usually only affects radio technicians, who put their heads beside much bigger and much more powerful microwave emitters than a domestic microwave oven. And even cataracts are only due to the heating effect.
