Twenty-eight percent might seem like a low number, the researchers say, but it's significant given that RNA can degrade over time, so fresher samples would likely be more accurate.

Why didn't they use fresh samples since they know RNA can degrade overtime? How old were these samples?

For hypothesis initiation studies, you go with the best samples you have or can get for free. Collecting and analyzing fresh samples takes money. Like it or not, that's the way science works. I assume both of you are in favor of better ways of early detection of cancer???
