The star posted the message, together with a snap of her dog Kiera, on Instagram.
Cheryl, who recently celebrated her 30th birthday, told fans: "This is my dog Kiera. I have had her since she was two months and I was 16.
"Tomorrow she has radiotherapy and will be in doggy hospital for 2-3 weeks.
"Will you help me send her happy vibes and pray for her with me please?"
The former X Factor judge, who has four dogs, said: "She's my oldest baby and it's breaking my heart."
