18 Months of Unexplained Symptoms Led to a Life-Threatening Diagnosis

Taryn Elder thought she was living her “dream life” on the Gold Coast, building a career in tourism marketing while exercising and making the most of Queensland’s outdoors. Then a series of seemingly minor health problems began to worsen.

At 39, she put her constant exhaustion down to long commutes, the pressure of a contract job and the demands of everyday life.

Repeated sinus infections were diagnosed as viral illnesses, aching legs were attributed to walking, and night sweats were blamed on inadequate air conditioning.

Even when her fatigue became so severe that she would sleep for hours after exercising, Taryn continued to rationalise what was happening. She believed she simply needed more rest.

“I was a healthy 39-year-old living my best life. Then my life changed overnight,” Taryn, now 40, told the Daily Mail.

After more than a year of unexplained symptoms, a blood test in March 2026 delivered the diagnosis: acute myeloid leukaemia (AML), an aggressive form of blood cancer.

Within days, she had relocated to Victoria to be closer to family while undergoing intensive chemotherapy.

Symptoms explained away

The first warning signs appeared 18 months before her diagnosis, with persistent fatigue, recurring sinus infections and aching muscles.

The infections would clear before returning again. Fitting medical appointments into her lunch breaks, Taryn often saw whichever doctor was available.

“Every time they said, ‘It’s viral, we can’t really do anything. You obviously have pretty bad sinuses,’” she recalled.

One infection became so serious that she was referred to an ear, nose and throat specialist. Surgery was recommended, but taking several weeks away from work did not feel possible.

“I was working really hard because it was on a contract, so I was really trying to prove myself,” she said.

Instead, she doubled down on self-care, exercising regularly, eating well and making an effort to get more sleep.

Still, further symptoms appeared. She assumed her sore legs were the result of walking, while the night sweats were put down to the lack of air conditioning.

A visit to Victoria for Christmas in 2025 exposed just how unwell she had become. A Pilates session left her needing hours to recover, and socialising felt beyond her, but she continued to blame the exhaustion on a particularly demanding year.

Back in Queensland, exhaustion intensified. She napped through lunch on work-from-home days and withdrew socially. 

‘I can’t explain it. I just feel so burnt out… I shouldn’t be feeling this way because I’m trying to do all of the right things,’ she confided to her aunt, who urged her to get blood tests. 

Searching for answers

Approaching 40, she wondered about hormonal changes and booked a long appointment, requesting comprehensive tests. 

‘You hear so much about perimenopause and hormonal changes when you get into your late 30s and early 40s, and so I just wanted to find out what was going on,’ she said.

Travel delayed the tests, but when completed, she received urgent calls from her clinic. Breathless after gym, she was told to come in immediately and bring a support person. 

Her doctor explained that abnormal cells suggested AML. 

‘What is that? Am I going to die?’ she asked.

A bone marrow biopsy confirmed it and within hours, she was on a plane to Victoria, leaving behind her job and friends who packed up her home.

‘I just thought I was a normal person and I would never go through a cancer diagnosis,’ she said. 

Five months of chemo

Her first hospital stay lasted five weeks. The chemotherapy was brutal – she received 10 blood transfusions, battled infections and recovered only to enter another four-month hospital cycle. 

In total, she spent about 100 days as an inpatient. 

Usually energetic and extroverted, she found herself hiding away. 

‘I’m usually a very vibrant and out-there person. But when I found out, I just pretty much went and hid. I didn’t really want to talk to anyone.’

She then lost her hair and barely recognised herself. 

‘I felt like a shadow of myself,’ she said.

Remission brought hope – and a ‘deep molecular response’. 

She then entered a clinical trial at Barwon Health, hoping a new vaccine would train her immune system.

‘I feel very privileged to be on that trial. My diagnosis may do some good for future patients… and hopefully save my life at the same time.’

Yet life remains changed. She now lives permanently in Victoria, expects at least another year of maintenance treatment and has recently been approved for part-time freelance work. 

‘I have really had to leave my ego at the door and just slow down,’ she said.

Learning to live slowly 

In Barwon Heads, Taryn walks, spends time with her dog, illustrates again and sees a psychologist to process everything.

And as her immunity recovers, she is reconnecting with friends.

‘I just have to be really kind to myself and remember that I’m not the same woman that I was before the diagnosis, and it will be a rebuild,’ she said. 

The experience changed how she thinks about her symptoms and about self-advocacy. 

‘I think that we all get so busy that we put off those medical appointments and those tests, and I just really need people to understand that you absolutely shouldn’t. You should always listen to your body if you know something’s not right.’

The strangers helping keep cancer patients alive

One of Taryn’s biggest surprises was realising how much cancer treatment depends on strangers. She needed 10 blood transfusions in her first hospital stay and learnt that future patients may need stem cell transplants from matched donors.

Trying to make sense of her experience, she used her professional skills to advocate publicly for blood and stem cell donation. 

Friends and strangers alike responded; she later helped raise $15,000 for the Andrew Love Cancer Centre. 

A $1,000 donation came from a woman Taryn had never met, who told her she’d received the same diagnosis 30 years earlier: ‘She said, ‘I am on the other side of this, and you will be too.’

How to register as a stem cell donor 

Taryn now urges eligible Australians to learn about stem cell donation, having discovered how vital donors are for blood cancer patients. 

Registration is straightforward: your tissue type is recorded so doctors can search for compatible matches if needed.

‘I think there’s a really bad stigma around becoming a stem cell donor. But if you ever get the call up, you’re actually saving someone’s life,’ Taryn said.

Her cancer diagnosis may have forced her to give up her home and career, but it revealed how far people will go for someone else. Friends packed her house; family sat by her side. Strangers gave blood and money, helping keep her alive.

‘Going through a diagnosis like this, you realise what’s important in your life. It’s all of the people that show up for you.’
