We've got a 35 year old female firefighter here with cancer, so I can relate. Let me know the address, and I'll send off one of our patches. Our firefighter has a website: teamtrish.org it may be helpful to your cadet to know that they're not alone in this. Best wishes...stay safe!
I am a DOD firefighter/EMT at Camp Lejeune. if you send me your address i can send you one from my base and from a few other stations i have been a part of.
