(CNN) — Sarah Ferguson, Duchess of York, has undergone surgery after being diagnosed with breast cancer, she revealed in an episode of her “Tea Talks” podcast released on Monday.

During the podcast, which was recorded the last week before his surgery, Ferguson said, “I’m going to have a mastectomy tomorrow.”

“I want every single person who listens to this podcast to get vetted, get tested, and do it,” Ferguson said.

Ferguson was reportedly discharged from King Edward VII Hospital in Marylebone, central London, on Sunday and is recovering with his family in Windsor, according to the British Press Association (PA).

According to PA, a spokesperson for the Duchess said: “Sarah, Duchess of York, was recently diagnosed with an early form of breast cancer detected during a routine mammogram.”

“He was advised that he was to undergo surgery which was successfully performed,” according to PA.

“The Duchess is receiving the best medical care and her doctors have told her the prognosis is good. She is now recovering with her family.”

The spokesperson added that the Duchess expressed her “tremendous gratitude” to the medical staff who supported her and to the staff involved in the mammogram.

His illness was otherwise “symptom-free” and Ferguson “believes his experience underscores the importance of regular check-ups,” the spokesperson said, according to PA.
