"I think by feeding my body good things, it will have an impact. I've done a lot of scientific research into it."
Make-up artist Sarah was diagnosed with cancer after she noticed an indentation on her left breast, as she danced naked in front of her 60-year-old mum Annie Herbert's mirror in Bermondsey, south London, on December 3 last year.
Sarah, is now following an alkaline-based vegan diet - believing it will give her the best chance of beating the disease, which has previously affected several members of her family.
And she hopes her extreme measures will reverse the progress of her currently stage 1 cancer, which is made up of two tumours measuring 2.1cm by 1.7cm and 1cm by 1cm.
"If it doesn't work, I will reconsider my options, but at this stage I am trying this," she said.
Sarah also believes that surgery could damage her health.
She continued: "I think I stand a better chance doing this than having a mastectomy straight away.
"I believe if I had a mastectomy I would be dead within 10 years. This is about healing my body back to health.
"I'm 100% sure that my cancer is emotional.
"I've been dealt some really terrible hands in my 36 years, but that's all in the past and I'd really like to show the Big C the door.'
Sarah's diet was never bad. She would eat free-range eggs, well-sourced meat and good quality butter.
Additionally, she was careful not to take hormones in tablets or her food and favoured natural products.
"I used bicarbonate of soda instead of deodorant, never had any hormones in pharmaceuticals or food, ate healthily and breastfed all my children,' she said. 'I couldn't believe that I got ill.'
Sarah discovered her lump after stepping out of the shower and dancing in front of the mirror.
"I thought I'd lost weight, so was dancing around a bit," she explained. "It was then I noticed the lump." Two days later, on December 5, she headed to her GP, who referred her to the breast clinic.
On December 19, at Buckland Hospital in Dover, Kent, a doctor examined her and, concerned, referred her to Kent and Canterbury Hospital, Canterbury, for an ultrasound, needle biopsy and mammogram.
But it was not until December 30 at William Harvey Hospital in Ashford, Kent, that her cancer was confirmed.
"I knew already," she recalled. "As soon as I saw the indentation and felt a lump I realised."
Sadly, this is not the first time Sarah has been affected by cancer.
Close family members have had it and her childhood friend, professional footballer Ernie Cooksey, died in 2008, aged 27, after battling skin cancer.
"Maybe my experience of the illness has made it easier for me to cope," she said. "I've seen people go through chemotherapy and be very ill as a result.
"And I've heard about others having mastectomies and still not surviving."
Now Sarah is speaking out to make people aware that breast cancer can affect anyone and that a lump is just one sign. She hopes to get #Shakeyourtits - a hashtag encouraging people to examine their breasts for changes including lumps, indentions, changes to the skin and bumps - trending.
She said: "We should all be shaking, massaging, feeling our way around to spot any changes in our breasts as soon as possible."
Sarah also needs £30,000 to fund her natural treatment.
"I need to get vitamin C drips, supplements, a water distiller, thermo imaging to check tumour shrinkage and hormone-testing reports," she said.
