I nearly died after I tried to cure my cancer with a carrot juicing diet I found on Instagram

Nothing, it seemed, could deflect Irena Stoynova from her route to self-destruction. Hours from death and unconscious, she was admitted to a Surrey hospital last year after being 'brainwashed' into treating her advanced cancer with a juicing diet.

Even as she lay in hospital — too weak to move and struggling to breathe; her arms emaciated, her stomach bloated with fluid and her body covered in cancerous lumps — she obdurately refused life-saving chemotherapy.

'I was in a pathetic, delusional state,' she recalls now. 'By then I was having hallucinations. I couldn't walk. I couldn't speak without gasping for air.

'My abdomen, legs and lungs were full of fluid, yet the rest of me was stick-thin. I had lumpy nodes all over my body. But I'd chosen my path. I was sold.

'I was convinced I could treat my cancer holistically, starve it to death with a juice diet. I believed all the anti-pharma conspiracies I'd read about on the internet, that doctors are all financially motivated and that you can drive your cancer away with a toxin-free diet.

'I became obsessed, as if I was in a sect. I believed chemo was the easy way out, what lazy people do. I was persuaded that I didn't want this poison in my body; that I shouldn't cheat. I believed that 13 cups of carrot juice a day would heal me and I followed this "holistic" programme for two-and-a-half years.'

Today Irena, 38, who works in sales, looks radiantly well. Tall and striking, her skin is glowing, her energy restored and the cancer — after six rounds of chemotherapy at Frimley Park Hospital in Surrey — is in remission.

Now she is an enthusiastic advocate of the modern medicine that saved her life and urges those diagnosed with cancer to follow their doctors' advice: 'Their knowledge is founded on evidence-based experience. Do not listen to internet gurus and influencers who try to persuade you otherwise.'

So what finally changed her mind? And how did she get to the point where online 'gurus' seemed more trustworthy than medical doctors?

Irena's story is a very modern cautionary tale, a disturbing illustration of what can happen when social media sucks someone into a pernicious anti-science world and convinces them only it can solve their problems.

It was consultant haematologist Dr Clare Rees who, through her calm perseverance, eventually convinced Irena she would die without chemotherapy. But for ten days — even after her emergency admission to hospital — Irena remained stubbornly resistant to conventional medicine, intent on pursing her quack regime.

'Once you search 'healing cancer alternatives' on the internet you are bombarded with people telling you you can cure your cancer with juice and herbs,' says Irena.

She noticed enlarged lymph nodes on her body. Her GP offered an immediate consultation. 'She said there and then that it was cancer,' Irena says

'I thought the doctors had been indoctrinated when it was me who was being brainwashed. I wasted two-and-a-half years, barely existing, when I could have had an active and vibrant life if only I'd had the treatment doctors recommended when I was first diagnosed.

'Instead, I stopped having scans and blood tests. I shut my doctors out completely. I lived on carrots and broccoli and I became completely isolated. My only support was listening to podcasts because if I spoke to anyone else, they'd say, 'You've got to go to hospital for treatment'.'

Irena's story begins in May 2021 when she noticed enlarged lymph nodes on her body. Although Covid made it hard to get doctors' appointments, her GP was concerned enough to offer an immediate consultation.

'She said there and then that it was cancer, which I thought was extraordinary as I hadn't had any tests.'

Biopsies confirmed that Irena had non-Hodgkin's Lymphoma, an incurable but very treatable type of cancer that develops in the lymphatic system (the network of vessels and glands spread throughout the body, which is part of its immune system).

At the time, Irena was living in Derby while her partner, Ivan Kalmukov, 39, a vet, was in Hampshire finishing his training.

'I was on my own when I went to see the consultant, who diagnosed stage four cancer and, that night, I did not sleep. The biggest challenge is acceptance. I was doing all the right things — I didn't smoke or drink; I never ate junk food and I'd been vegetarian for 15 years — so the shock was profound.'

The dangerous diet's effect on her body was shattering. Her weight plummeted to 50kgs (7 st 12 lbs). 'My arms were just bones, but my stomach was full of fluid,' she says

To compound her worries, and by terrible coincidence, on the very same day Ivan was diagnosed with Motor Neurone Disease, a rare and incurable condition that affects the brain and nerves causing weakness and muscle-wasting.

'I was more worried about Ivan and what the future held for him than about myself. All our dreams and plans were taken from us.'

She is warm and positive, but the memory brings tears.

'There was a nurse in the room when I was given my diagnosis and they drew up plans, including chemo. As I was 36, they offered to freeze some of my eggs. I agreed everything. I was in a state of shock.'

That evening she went home and cried. 'Then I thought: "This is my Everest. I am going to climb it myself." I Googled, "How to treat cancer holistically" and everything started from there.'

Quickly, she stumbled on a social media account in which a best-selling author, with hundreds of thousands of Instagram followers, said he refused chemo and opted for diet and natural therapies instead.

'I bought into this mind-set,' says Irena now, 'and believed the rhetoric that cancer is created by your body and can be destroyed if you starve it to death with a toxin-free diet.'

Irena spent £2,000 on four different juicers (one for carrots, another for smoothies, one for citrus fruits and yet another for everything else) and scoured shops for fresh, organic fruit and vegetables, buying around £1,000 worth a month.

Following the influencer's regime, she drank only juices for 60 days, added whole raw fruit and vegetables for the following 30 days, and then added nuts for 90 days. Preparation of this largely liquid diet took up to four hours a day.

'I read all his books, followed him on social media and — although I did not speak to him (telephone consultations cost £80 an hour) I listened to his podcast. He articulated his message so strongly and beautifully I became obsessed.

'I was like a sponge. What was most persuasive was that he had testimonials from survivors and healthcare professionals who endorsed him.'

It's a message that has since been debunked by a prominent doctors, however, while many question why Amazon continues to sell his books.

I wonder what Ivan — who first met Irena at school in their native Bulgaria when they were seven years old — thought of her alternative approach. After all, he had studied veterinary medicine.

Finally accepting she should start chemotherapy, Irena said: 'Hit me with it hard'

'He knows me better than anyone, knew how stubborn and determined I am, and he made me promise I'd have blood tests and scans and that I'd start chemo if the diet didn't work.' She looks chastened. 'But I failed to keep my promise.'

The juicing diet took a devastating toll. 'I've always been lean and fit,' she says. Previously, she worked as a model to help fund a degree in business administration and a master's in marketing.

'I really wanted to believe the diet was working but I felt weak. I didn't have any energy at all.

'After a month or so I couldn't concentrate. I didn't have the energy to go to the grocery store to buy the five kilos of carrots I needed to juice every day.

'The fatigue I felt was unimaginable. But I am persistent and determined. I continued the diet. I still went to work.

'I knew it was going to be a really hard path but I was convinced it was the right one. I believed chemotherapy was a poison, that its effects would be monstrous.'

In February 2022, she moved to Hampshire to live with Ivan.

'I was drinking a cup of carrot juice every hour, taking four or five bottles to work with me. I didn't have a single day off work.

'My colleagues said, "You're not well. You need help." But I knew it was a two-year journey, that there were no shortcuts. Ivan and I had some heated arguments.

'He was devastated to see me so weak and struggling. He even gave chemo to people's pets, but when he begged me to have it, I'd get upset and stop talking to him.'

Meanwhile, the effects on her body were shattering. Her weight plummeted to 50kgs (7 st 12 lbs). She is 5 ft 8 in tall: 'My arms were just bones, but my stomach was full of fluid.'

She found a recipe elsewhere on-line for an herbal tincture to apply to the lymph nodes. 'It brought me out in a terrible itchy rash. I was like a wild animal, scratching and rolling over in bed. I kept taking cold baths.

'I listened avidly to podcasts, and tried other diets too, but there seemed to be lots of contradictory advice. One said don't eat soy. Another said you should. It was the same for proteins. I went on a diet that allowed me to eat 100g of cottage cheese a day with flaxseed oil and fruit.'

Following other advice, she gave herself enemas: 'So everything I'd eaten was gone.' She put iodine on her lumps believing it would destroy them. 'Actually it just burnt my skin.'

Having read that she should try to keep exercising, she exhausted herself bouncing for an hour a day on a mini-trampoline. She took saunas, tried to practice yoga.

By May 2023, however, she had capitulated: 'I couldn't do anything except sit, propped up on pillows. I was having hallucinations, to the point where I'd text Ivan and tell him my best friend had arrived from Bulgaria, or that a stranger was in the house and wouldn't leave.'

No longer able to work — she was gasping for breath and too bloated with fluids to walk — she drove to her GP's surgery to ask for a sick note.

'I had to sit in my car for 20 minutes to recover from the drive. I managed to drag myself to reception and asked for a wheelchair.

'When the doctor saw me, he was horrified. He ran some tests and said: "I've been in this practice for more than 30 years and I've never seen anyone as sick as you. Do you want me to call an ambulance, or will you?"'

A herbal remedy Irena tried to fight her tumours brought her out in an agonising rash

'From the moment I started the chemotherapy — I had my last cycle in January — I have felt great. I've also felt loved, supported and never judged,' Irena says

I said: 'I just want a sick note,' and he said, 'Do you realise you're committing suicide? You can't breathe, look how skinny you are.'

'I felt offended. I couldn't see how pathetic I looked. I said I was just waiting to get better. My doctor agreed he couldn't do anything without my consent. He pushed me to my car in the wheelchair.'

Her condition worsened. Three months later — in August — she was rushed, unconscious, to Frimley Hospital.

'Ivan said I'd stopped breathing for a few seconds several times during the night, so he called an ambulance,' she says, admitting that even though she was gravely ill she still felt 'very angry' with him for summoning help.

In hospital two drains were put in to remove the fluid from her body and lungs. 'Irena was hours from death,' says Dr Rees. 'I did not think I could persuade her to have chemotherapy. I admit I welled up. We all found her endearing but we were terrified someone as educated as she was could have been so brainwashed.'

Irena continued to refuse treatment, but Dr Rees was as determined as her patient was stubborn.

'Clare cried,' Irena recalls. 'She came to see me six times to try to persuade me how bad my situation was. She told me that even though the fluid in my body had been drained it would come back again. She wanted me to understand that she was there to help me, not poison me.'

Today there is a rapport between the two women, the consultant who quietly and doggedly stood her ground; the patient who resisted her until, one day, miraculously, there was a breakthrough.

'Clare asked if I was willing to meet another patient, a similar age to me with a similar cancer. She introduced me to Emma who was kind and positive. Emma told me that her treatment had not been aggressive, that the staff were all kind and supportive.'

The words seeped into Irena's consciousness: 'I had a conversation with myself. I realised I'd been wrong. It was very, very hard to admit I'd failed but it was a turning point.'

Ten days after her admission to Frimley Park, Irena spectacularly changed her mind.

'It was as if a switch had been flipped,' recalls Clare. 'We wondered if we should offer her a reduced dose of chemotherapy but she was just, "hit me with it hard".'

Irena spent 50 days in hospital having successive rounds of chemotherapy. 'From the moment I started the chemotherapy — I had my last cycle in January — I have felt great. I've also felt loved, supported and never judged.'

Her cancer in remission, Irena continues to be monitored. She will also undergo immunotherapy for two years. But her juicing diet has left its legacy. Extreme dieting and a vast intake of acidic juices have caused tooth decay and the beginnings of osteoporosis.

She cautions: 'If you're diagnosed with cancer, cry and feel miserable, then chin up, brave face on and plan your treatment with your consultant.

'The doctors know what is best for you. Everything is evidence-based and founded on years of experience and knowledge.

'If you need to go on a diet, your doctors will tell you. Don't be brainwashed, as I was, into thinking you can cure cancer with juice and herbs.'
