This is nearly certain to be oversold. The etiology and composition of brain tumors is highly diverse; they don’t all share the same biology and the study design here (100 “CNS tumors” vs. “normal” individuals) leaves a lot to be desired. It’s not clear to me if they also are basically using the same testing and training dataset or not.
Even the headline here (100% accuracy) is inaccurate; it had 100% sensitivity). The list of cancer bio markers which have turned out not to work for screening is quite extensive.
That said, the most interesting thing here is the microRNA capture technology. If it can be scaled, it might be interesting.

They used samples of pee of people that were diagnosed with CNS tumors with other methods, so my guess is that they had already big enough tumors to cause problems, so "regardless of its size or malignancy" is probably too optimistic.

"It can be sterilized, produced on massive scales and completed by patients any time anywhere with “minimal effort,” according to the study published recently in the journal ACS Applied Materials & Interfaces."
