Cystic Fibrosis in Japanese is "Nou hou sei sen i shou", but writing the kanji (picture words for those unfamiliar with the Japanese writing style) would be more appropriate for what you're doing.
The kanji is quite complicated, I could hardly even rewrite it. If you really want to add that to your project, I'd have to E-mail it to you because this forum does not support the necessary fonts for the language.
PM me if you really want to add the Japanese meaning as well!
Best,
