SHARON OSBOURNE, who has overcome cancer herself, is joining a host of famous names in a national Stand Up To Cancer television broadcast on October 17.

Other celebrities who are getting involved for strong personal reasons include TV presenter Davina McCall and chatshow host and comedian Alan Carr.

Former X Factor judge Osbourne said: "Having had personal experience of cancer, I know first-hand the devastating effect it can have on a person and their friends and family. But we can't sit there and let cancer take control of our lives - the more of us who show solidarity and Stand Up To Cancer together, the faster we can fight this deadly disease."

Osbourne previously revealed she had undergone a double mastectomy.

The 61-year-old beat colon cancer over a decade ago but opted for surgery after finding she carried a gene which increased the risk of developing breast cancer.

Meanwhile, McCall, who lost her sister to cancer in 2012, is returning to host Stand Up To Cancer's live TV show on Channel 4. She said: "I'm Standing Up To Cancer because my big sister, Caroline, had primary lung cancer, and because she was frightened of doctors, and kept making excuses, by the time we got to A&E she was given a terminal diagnosis."

Carr, whose friend suffered throat cancer, said: "My very good friend Sam lost her voice box to throat cancer and I saw how low she got, not being able to talk, but I see now how confident she is. Let's hope we can get loads of money to find cures as soon as possible."

Other celebrities taking part include TV presenter Christine Bleakley, Saturdays singer Una Foden, radio DJ Greg James, comedian Jack Whitehall and sports presenter Jake Humphrey.
