Like others said it looks like a mild case of warts.
The real small ones, and the ones around the eyes you can probably put some real strong vetrinary iodine on to discourage growth.
The medium- small califlower shaped ones, put the cow in a squeeze and use a sturdy pair of sissors to simply clip them off. Don't go too deep ( close to the hide) ,or you can whack the hide open. Even then the cow doesn't often appreciate your efforts to help her out.
After cutting them off put Iodine on the base that is left.
The bigger califlower shaped ones I have put elastrator rubber bands on to cut the circulation off of so they die back, and then use iodine for a while on the base of them.
The real big califlower shaped ones ( I have seen them as long as my thumb, --no joke!) I tie off tight with a slip knot using fishing string, so they die back so they fall off or shrink down to size so they can be clipped off and iodined.
They should be taken care of because they are contagious to other cattle, and I have seen some cattle looking absolutely awful they had so many warts on them.
Sometimes they go away on their own, but I have seen them spread to other animals.
If it is a show animal take care of it way before show day.
Saw a steer once at a 4-H show that looked like he had gone through a tree-de-barker, as he must of had an incredible amount warts that were cut off just before show day. Doesn't make a very good impression on a judge to go into a ring with a major amount of cuts on an animal.
