"Getting a working transfusion felt like having an energy drink. You would have this enormous pick-me-up and be pinging off the walls — you are so sick, and then suddenly you feel so alive."
June 14 is World Blood Donor day and Fox, unsurprisingly, said she could not emphasise enough the importance of being a blood donor.
"It's just so, so crucial."
Less than 4 per cent of New Zealanders are blood donors, a proportion NZ Blood very much wants to increase in order to help the 29,000 patients treated with blood or blood products annually.
Patients like Fox, whose cancer diagnosis while a pupil at Kavanagh College was a complete shock.
"We thought I just had low iron, and we got sent straight to Christchurch for treatment, so not even being in Dunedin was a shock to the system as well, but you soon adjust to life in hospital."
Although classified as a high-risk patient because of her age and low red blood cell count when she was diagnosed, Fox had a "good" cancer that could be treated.
"Fortunately I managed to come out the other side. January this year marked my five years off treatment so I was officially cured.
"If I get a cancer now it won't be a secondary cancer, it will be something completely different, although cancer is an ongoing thing. It will stay with me for life."
Getting better required more than 35 transfusions and several bouts of chemotherapy.
Fox is now sitting her final exams at the University of Otago to complete a bachelor of commerce degree.
"The sad thing is that I'll never find out who my amazing donor is.
"That's why I do a lot of work with NZ Blood, because if it wasn't for that person I might not be here."
