Former consultant obstetrician and gynaecologist Rob Jones is having his work treating women with growths 'reviewed'.
According to the BBC, concerns have been raised about Mr Jones's 'clinical competency'. The Royal Cornwall Hospitals NHS Trust confirmed that more than 1,500 women who were treated by him at Treliske in the past two years have been written to.
Mr Jones, who has now resigned, said he had always followed national protocols. He also said he had been a caring doctor throughout his career.
Paul Upton, the hospital's medical director, said: "There is a possibility that cancers have been missed and that is exactly why we are conducting this review."
Lezli Boswell, chief executive of the Royal Cornwall Hospitals Trust, said: "We want to do a double check to make sure they have received the appropriate care and treatment."
Regarding the delivery of Florence Cameron in 2010, who was delivered by emergency Caesarean section, she said that there was 'no reason to believe that the particular patient was placed in any risk at all'.
Mr Cameron said after the birth of Florence that the hospital and staff were "wonderful".
Ms Boswell said Mr Jones had worked at the hospital for 20 years. He was no longer employed by the NHS and had also voluntarily taken his name off the medical register after he resigned in May following another review into his work.
She said there had been concerns raised about his clinical competency since 2000 and eight reviews had been carried out into his work before he left in May.
"We are very very sorry for any anxiety and stress and pain it causes as a consequence of this," she said. She said the "first phase" of the review would go back two years.
"We will then review the findings of that, take expert advice on whether we need to go back further," she added.
