LCH is a rare disorder that can damage tissue or cause lesions to form in one or more places in the body.
Histiocytes are types of white blood cells which help fight infection. In LCH, histiocytes grow excessively and can gather in bones, skin, lymph nodes, lungs, bone marrow or the pituitary gland.
This can cause a variety of problems such as pain in the bone, skin rash, swollen tummy, or breathing difficulties.
“I believe everything happens for a reason, and this diagnosis has given me a new perspective on what really matters: my health,” Griffiths added.
“Rather than feeling disappointed about how my career has ended, I feel incredibly fortunate and grateful for the perspective this experience has given me.”
Newport-born Griffiths developed at the region’s academy and also played for Newport RFC before making his Dragons debut in 2014.
“Playing for Dragons RFC for over a decade and representing Wales has been the greatest honour of my career,” he said.
“The highlight will always be standing on the field at the Principality Stadium, singing the anthem, and feeling the pride of seeing my family in the stands.
“Nothing will ever compare to running out at Rodney Parade alongside friends I’ve battled with for years, leaving everything on that pitch together.
“Rugby isn’t just a physical sport, it’s a deeply emotional experience, going out there every week to put your body on the line. I don’t think anything will match the feeling of being in the trenches with my mates, giving it everything I had.
“Those were the moments I cherished most – win or lose – knowing I gave my all. That’s something I’ll miss deeply and always be grateful for.
“Thank you to everyone who’s been a part of my career.”
