Royse, who is married and has two teenage sons, had a lumpectomy and lymph node removal in June.
On Thursday she finished her chemotherapy treatment at Northampton General Hospital, adding: “The nurses were just brilliant, they took me through every step, explaining everything including all the possible outcomes.
“I felt like I was in very safe hands.”
Although she did not reveal to her treatment team that she was a nurse, she said they eventually worked out her job was in healthcare “as I was asking certain questions and they thought I’d got a little bit of knowledge, although it’s not my area of speciality”.
“Usually the last thing you want to disclose is that you are a nurse.
“Everyone is treated as a person and is treated uniquely.”
Royse is due to start radiotherapy in December, during which she will also receive HER2-targeted and hormone-blocking treatment.
She said it was a “very treatable cancer, being triple-positive treatment is available, I have gone for the whole shebang to throw at it”.
She added her one regret was having to put on hold plans to study for a doctorate in nursing, specialising in atrial fibrillation and arrhythmia at the University of Northampton, which could take up to six years.
“I’d wanted to do it for years, but I have to concentrate on my treatment and getting well and back to work,” she said.
