Strictly head judge Shirley Ballas revealed she was waiting for test results after health checks were prompted by worried TV viewers.
The 61-year-old was alarmed after viewers spotted a large lump under her arm and contacted her on social media to share their concerns.
In her update, she wrote: “Follow-up as promised. Today after not much sleep (my insomnia) and I took a trip to Kings College Hospital ultra sound department.
“I believe the nurse could sense my anxiety and immediately put me at ease with her beautiful bedside manner.
“As embarrassing as it is for me to be examined the Doctors and Nurses only have our best interests at heart.
Can I say social media can be a negative place but in this case I have only felt warmth and concern. The 1000s of messages I have received has been beautiful, thank you for sharing your own journeys with health.’
She went on to use her platform in order to encourage others to check themselves for lumps or abnormalities on a regular basis.
“Ladies keep checking your bodies no one knows your body better than you.
