Showing supremacy among the ranks and to fight other males for dominance. And when they grow their antlers long enough, they sometimes rub them against trees to rub the "leather" off their antlers.
Yes because they have to use extra energy to use them. If they lose their antlers, the energy that is usually used to grow them can be used to survive without much food in the winter.
white-tailed Deer usually start growing their antlers in late spring to early summer. The velvet ( the furry coating on the antler that makes the antler grow) is shed in early august and the antler is shed after the rut (deer mating season) in November.
Elk, have there caves during late spring, May or June usually.

Deer grow a new set of antlers each year. The new antlers are covered in a kind of velvet. Because of fighting and searching for food the velvet becomes rather tatty, often hanging down in strips. This can reduce the animals vision, which is highly important to such an animal. So it rids itself of the offending velvet by rubbing its antlers against trees. The bare antlers are used especially in the "rutting" season (the mating season) when the strongest deer, usually with the largest and perfectly shaped antlers, will be able to assemble his own herd of females. Later in the year the antlers are "cast" off, but the material of which they are made is not wasted because the deer will gnaw away at the antlers to take in the stuff needed for antlers to grow once more.
After the end of the rut, usually in winter. New antlers soon grow back.
