Popular British author Sarah, Duchess of York is in recovery after undergoing a successful cancer operation.

Sarah is the former wife of Prince Andrew and has published several books.

The 63-year-old discovered that she had an early form of the disease during a routine mammogram.

Despite the discovery, she has undergone a successful operation and is now in recovery after leaving the King Edward VII Hospital in Marylebone, Central London.

The hospital has treated members of the Royal Family for decades.

Sarah's spokesperson revealed that she is now with her family in Windsor.

Before entering the hospital, Sarah Ferguson opened up about her diagnosis on her new podcast Tea Talks which is released on Monday.

The episode was reportedly supposed to be released on Thursday but has been postponed until after her operation.
