ill Turnbull is worried about getting "hot flushes" on \'Good Morning Britain\'.
The veteran broadcaster has been fighting prostate cancer and one of the side effects of his hormone treatment medication is that he sometimes experiences hot flushes.
Although Bill is feeling "really good" at the moment he is "nervous" about how he\'ll cope if experiences an episode when he reunites with his former \'BBC Breakfast\' co-host Susanna Reid on the ITV breakfast show later this month.
Bill - who is filling in for Susanna\'s regular co-host Piers Morgan - said: "When you have cancer, it\'s always there. But currently I feel really good, most of the time. I have changed my diet considerably and in the past few months I have felt healthier than I have in a long time.
"The only thing I do have is, because I\'m on a hormone treatment, I do get hot flushes sometimes. I\'m a bit nervous as it could be slightly awkward in the studio.
"Normally what happens if I get a hot flush, I get all red in the face and I take my jacket off and cool down. I\'m not sure I\'m going to be able to do that. We may need to get a little fan."
And the 64-year-old presenter explained his age actually concerns him more than his illness when it comes to returning to TV screens.
He added: "On a work front, I measure it more because of my age than my illness because I can\'t run around as much as I did at 30 or 40.
"I make sure I don\'t overdo it. Occasionally, I turn things down, if it means a lot of travel and work."
Bill has described the upcoming three-show stint as a homecoming, and he hopes his former BBC colleagues will be "glad to see" him back at work even if it\'s with a rival channel.
He said: "Oh gosh! I don\'t know [what they\'ll think]. I hope they will be glad to see I\'m still working. They are still very good friends of mine.
"I\'m just back in the game, I suppose. Television Centre is where I started in television more than 30 years ago, and presenting 20 years ago. I never imagined I would be able to do a show from there again. It\'s great, \'Good Morning Britain\' is there. So, in some ways it\'s like coming home."
