90 mm Summicroon-R with small spot of fungus. Salvageable or paper weight?

I just had given to me a Leitz Canada 90mm f2 Summicron-R lens with a 1mm. diameter spot of fungus on the inside element in the middle. Is it worth getting cleaned or is it a paper weight?

A competent service person can easily remove the small fungus, no need to worry too much if it is a new growth and relatively small.
