"NANA was never cancelled, not the anime nor the manga - the anime caught up and the manga was on hiatus (and, years later, still is) due to the mangaka being hospitalized, they had no choice but to stop the series because they ran out of adaptable material and didn't want to really make shit up in such a great show.
That's just being unfinished, not cancelled. The show was doing great, fine and dandy, it just had to be ended because of lack of material."
Got this from someone else.
