“That which exists is not the same as existence itself.” (ST I, q.3, a.4)

In fact MMA is much safer than boxing.

In boxing you have the repeated blows to the head resulting in long term brain injury.

The "punch-drunk" syndrome.

In boxing the primary target is the head.

In MMA you have a single blow to the head instead of multiple repeated blows.
