“I’d also like to say thank you to AFC Bournemouth for all of their support and assistance this past week.”
Brooks has played nine times for Championship side Bournemouth this season, but his football career will now be on hold as he begins treatment.
“Although I appreciate that there will be media attention and interest, I would like to ask that my privacy is respected in the coming months and I will share updates on my progress when I am able to do so,” Brooks added.
“In the meantime, thank you to everyone for their messages of support – it means so much and will continue to do so in the months ahead.
“I look forward to seeing you all again and playing the sport I love very soon.”
Both Wales and Bournemouth have offered their support and best wishes to Brroks during his treatment.
