How to cut some text?

I have long section titles in my document like:

Lorem ipsum dolor sit amet, consectetur adipisicing elit. Proin nibh augue, suscipit a, scelerisque sed, lacinia in, mi.

Now I want to place it in page header but it is to long for it. Is there any way to cut text in LaTeX? I want to have it like that:

Lorem ipsum dolor sit amet, consectetur...

Is that possible?
