The couple met in 2020 when they were working together at Pilgrim Hospital in Boston.
They moved in together with Mrs Barlow’s daughter, now 10, and had two more girls, who are three and two.
Mrs Barlow initially phoned her GP surgery after finding blood in her stool. She was diagnosed with endometriosis over the phone and given medication, Mr Barlow said.
An appointment was booked for her to visit the gynaecology department at Pilgrim Hospital in January, but in mid-December, she became ill at work.
Mr Barlow said he had tried to take her to the GP, but was advised to go to the urgent treatment centre at Pilgrim Hospital.
However, according to Mr Barlow, the hospital said because she was already under treatment for endometriosis, there was little they could do.
Mr Barlow believes that had a blood test been taken at either the GP surgery or the hospital, the cancer could have been discovered.
