The difficult thing for me is that while I believe radon can cause lung cancer, I think products are often sold based on fear. “Second leading cause” doesn’t really mean anything in isolation, does it?
What slice of my mortality pie was radon before and after spending $5000? Could I spend $5000 to cut a bigger slice out of it in another way, like eating better or hiring a grizzly bear to make me exercise more often?
I think action is better than decision paralysis, but I wish I could make much more informed decisions.

You'll never know. The same way people in the exclusion zone will never know if their thyroid cancer was always destined to be or if it really was related to the Chernobyl meltdown.
But spending (closer to $1000) to mitigate some risk from a known threat vector does seem thrifty.
Of course anyone can restore from backups. It's a pain and it's time consuming.
My post serves more as a warning to those who may develop buyer's remorse.
