Vicky Sewart said she was concerned about the side-effects of the medicine which she was offered so opted to treat her condition with a health regime involving exercise and special foods.
She used a range of ‘superfoods’ including the spice Turmeric used in curries which she claims “makes cancer cells commit suicide”.
She said she used the spice in dishes including curries, stir-fry and a range of other food.
Now, four years later and with no sign of the cancer coming back, the 44-year-old is at the centre of a research project to study how lifestyle can be used to help other victims of the disease.
Vicky from Plymouth, Devon, told how she had an operation to remove a breast and lymph node in June 2008.
After Vicky, who runs the Victoria Sewart Contemporary Jewellery Gallery on the Barbican, in Plymouth, was diagnosed with a fast-growing tumour she underwent chemotherapy, radiotherapy and surgery.
But then she shocked doctors and her family when she refused to take Tamoxifen during remission ~ saying she would be using her diet as her anti-cancer ‘drug’.
Vicky said: “It’s very unusual for breast cancer patients not to take the drug.
“When I told the doctors I didn’t want to take it, they just advised me to keep oestrogen out of my body, which is basically what the drug does.
“The doctors absolutely will not say that the diet is going to do anything to help the cancer in any way, other than to say a healthy diet is going to help in the fight against any disease.
“This was four years ago and I think attitudes are changing a bit now so that these ideas are running alongside the more usual treatments.
“I believe absolutely enormously that my diet has assisted my recovery.”
Vicky researched foods which, according to anecdotal evidence, might have helped the recovery of breast cancer patients.
At first, she adhered to a very strict diet. She became a vegan for a while and cut out all dairy produce. She also added ‘super-foods’ to her diet and ate almost entirely organic.
Vicky said: “Fresh fruit, vegetables and juices are great, and frozen berries are fantastic as a superfood.
“Turmeric kind of makes cancer cells commit suicide and ginger and garlic are great to cook with.”
She prepares all her food from scratch, makes her own body lotions from natural ingredients and only uses chemical-free cleaners and detergents.
“I decided that I was going to help myself and do as much as I could,” she said.
Another element of her lifestyle is moderate exercise, which she believes was helpful in her recovery from cancer.
Vicky made her decision based on the side effects she could expect from Tamoxifen.
“It was the worry of the drugs and the side effects, I didn’t want to have to worry about it, I wanted to be free,” she said.
The national research study is looking at how lifestyle can help prevent the recurrence of breast cancer after surgery. It is the largest of its kind in the world, involving 56 hospitals around the UK and 3,400 patients who have had the disease.
For the past four years, Vicky has provided blood and urine samples and filled in regular questionnaires about her well-being, diet and lifestyle as part of the national research.
She has another year left of the trial and some findings are expected later this year and the full results will be published next year.
Vicky is hoping to mark her five-year remission in August 2013 and is getting ready to marry her fiance Michael in September.
She added: “People can die, or come back from it and enjoy life, you’ve just got to be thankful you’re still around. Make the most of life, everything will always be alright in the end.”
Dr Steve Kelly, an oncologist specialising in treating patients with breast cancer, based at Derriford Hospital, said: “Breast cancer deaths have been going down steadily for over 20 years thanks to surgery, chemotherapy and radiotherapy – all have helped.
“But there are three things patients can do to help themselves, it doesn’t guarantee survival, but it does help.
“The first is to exercise for thirty minutes three days a week, the second is to not gain any weight and the third is to reduce fat intake.
“These things help to reduce the chance of cancer coming back. For this patient, four years on now, it is still early days.”
Vicky’s father Dr John Sewart, aged 85, from Saltash, said: “I gave her advice when she asked for it.
“I was answering as a father first and a doctor second. It wasn’t difficult, I agreed with what she was planning to do, and I agreed with her decisions.”
