Cleaning internal fungus on Hexanon 200mm f4
1

I just got a Hexanon 200mm f4, and noticed some fungus on an internal element.

A) Is this easy to access / clean? If so, how?

B) Is it worth it? Can internal fungus infect other lenses or my camera?

It appears to be on either the second or third element from the front.
