About World NF Awareness Day
World NF Awareness Day is observed on May 17 as part of the wider May NF Awareness Month. The Children’s Tumor Foundation (CTF) currently uses May 17 for World NF Awareness Day and separately identifies May 22 for NF2-SWN awareness.
NF refers to a group of genetic conditions that can cause tumors to grow on nerves. This guide is for observance context and does not diagnose any individual condition.
Why World NF Awareness Day matters
The day helps make neurofibromatosis and schwannomatosis more visible and gives affected people, families, clinicians, researchers and advocates a shared awareness date.
Personal stories can be powerful, but participation should protect patient and family privacy—especially when children or medical details are involved.
History of World NF Awareness Day
CTF archival material documents World NF Awareness Day on May 17 by 2013.
CTF says its Shine a Light on NF campaign launched in 2014; that campaign is part of NF Awareness Month but is not treated here as the founding event for World NF Awareness Day itself.
Current CTF material continues to distinguish May 17 World NF Awareness Day from May 22 NF2-SWN Awareness Day.
