Cedar rust

I have two old junipers that are covered in cedar rust and I am wondering if taking then down would be better all around or is trying to treat them?  

There is no treatment I am aware of. Once infected the cedar remains infected. Apples and pears (and relatives) generally get infected on deciduous areas and reinfect every year. I do have some hawthorns that seem to stay infected.

I cleared the cedars and replaced with holly for wind and habitat.
