Sports presenter Clare Balding said she was "hugely relieved" that her throat cancer treatment had been a success.
The 38-year-old BBC star has had a scan after radioactive iodine was used to help her battle her illness, and said it appeared that all the "nasty bits" had been "zapped".
Balding has said previously that she has not felt "woe is me" over her thyroid cancer.
Writing on her website under the headline "Good News!", Balding said: "There are no signs of the thyroid cancer having spread anywhere else so all is looking happy and rosy in the world.
"I am hugely relieved and very grateful for all your support, particularly to those people who have had thyroid cancer and got in touch to share their experiences with me.
"I can't tell you how much this helped me get through the treatment process."
Balding now plans to throw herself into her job.
She said: "Now, it's full steam ahead with a busy summer of work."
The presenter caused controversy earlier this year by poking fun at Grand National winner Liam Treadwell's teeth in a post-race interview.
She had been told just days beforehand that a cyst in her thyroid gland was malignant.
But she decided to delay the operation until after the race at Aintree and told only those closest to her about her illness.
In an interview with the Daily Telegraph in June, she said: "I didn't tell anyone other than my family and friends as I didn't want to be treated any differently.
"You hear the word 'cancer' and you think it is a death sentence. In fact, the shock is the biggest thing about a diagnosis of cancer."
She first noticed a lump on her throat as she watched herself on TV at the Olympia Horse Show just before Christmas.
Balding, who lives in Chiswick, west London, previously said she had not "freaked out, cried a lot or felt 'woe is me"' since being diagnosed with the disease, and would prefer not to receive sympathy as she would find it "exhausting".Reuse content
