Thanks,Liquidstone
I may have this kind of "mechanical aptitude and nerves of steel to DIY", but I have no prior experiences, so that's why I am here asking for professional help.
Good luck on the job.... better to do it sooner than later, whether DIY or Canon service. Meantime, it's probably a good idea to regularly expose the lens to UV light (e.g. early morning sunlight) to arrest or slow down the fungal growth.
I see that you're from Taiwan and it's often the case that typhoons slamming our northern islands go your way. The high humidity in our parts are indeed tough on lenses. I've lost these favorite glass to fungus - my prime sharp 100-400, 400 5.6L, 100 2.8 macro, and many consumer lenses. I tried to save my 100-400 by having it cleaned by the local Canon service, but when it came back it wasn't as sharp as before (I suspect the complex design makes it tough to put everything back in good specs).
Interestingly, my 400 2.8 IS and my previous 500 f4 IS weren't affected by fungus even after over a decade of use, and these big whites were sometimes exposed to rain during birding.
