Radio presenter Adele Roberts thanked fans for their support and said "God bless the NHS" following her bowel cancer surgery earlier on Thursday.
The Radio 1 DJ said fans had kept her going and said she should hopefully soon be well enough to leave hospital.
"I’ve not really been on my phone but my family have been telling me how wonderful everyone has been", the 42-year-old said on her Instagram.
"You’ve brought them so much comfort. From the bottom of my heart thank you."

Adele, who was a contestant on reality series Big Brother in 2002, first revealed her bowel cancer diagnosis last week on social media.
In a post to her 141,000 Instagram followers, the radio DJ said she had been struggling with her digestion for a while and had received a diagnosis for bowel cancer.
She then urged her followers to get checked for bowel cancer.
"Sadly it can affect anyone, at any age, anytime. It doesn’t discriminate. Early detection can save your life", she said.
In her post following surgery, Adele called the NHS "angels on earth" and "so special". She ended her message by again urging fans to get checked.
"Please go and see someone if you’re worried about anything that’s not normal for you," she said."I don’t want this little horror taking any more of us."
