Sarah Ferguson, Duchess of York, undergoes surgery after breast cancer diagnosis

Sarah Ferguson, the Duchess of York, has urged people to make sure they have checks for cancer after disclosing she has undergone surgery herself for the disease.

Ferguson, 63, the ex-wife of King Charles's brother Prince Andrew, had successful surgery after breast cancer showed up in a routine mammogram screening, her spokesperson said on Sunday, with her prognosis said to be good.

In a podcast released on Monday, which she recorded the day before the surgery, Ferguson talked about the importance of having the medical checks, referencing her father who had died of prostate cancer.

"It's very important I speak about it. I don't mind if no one wants to hear from me," she said in her podcast Tea Talks with the Duchess and Sarah.

"I am telling people out here because I want every single person listening to this podcast to go and get checked, go and get screened."

Her spokesperson said the duchess was recovering at her home in Windsor where she lives with Andrew. Despite their divorce in 1996, the couple remain close friends.

Ferguson hailed National Health Service staff who discovered the cancer and helped her with the treatment.

"A really big shout out for the NHS and for helping me, and … all the doctors and nurses, the hospital staff that are working so hard to help me and the lovely nurses that are so comforting, and the counselling," she said.

The duchess — well known by the nickname "Fergie" — has forged a new career as a successful author after her divorce from Andrew.
