Why I believe that giving up milk is the key to beating breast cancer

PROFESSOR Jane Plant is a wife, a mother, and widely respected scientist who was made a CBE for her work in geochemistry. When she was struck by breast cancer in 1987 at the age of 42, her happy and productive existence seemed destined to fall apart. But despite the disease recurring a further four times, Jane refused to give in. As she describes in an inspiring new book, serialised by the Mail this week, she devised a revolutionary diet and lifestyle programme that she believes saved her life and can cut the chances of other women falling prey to the disease. Her theory remains a controversial one — but every woman should read it and make up her own mind. Today, she explains her personal breakthrough...

I had no alternative but to die or to try to find a cure for myself. I am a scientist — surely there was a rational explanation for this cruel illness that affects one in 12 women in the UK? I had suffered the loss of one breast, and undergone radiotherapy. I was now receiving painful chemotherapy, and had been seen by some of the country’s most eminent specialists. But, deep down, I felt certain I was facing death.

had a loving husband, a beautiful home and two young children to care for; I desperately wanted to live. Fortunately, this desire drove me to unearth the facts, some of which were known only to a handful of scientists at the time.

Anyone who has come into contact with breast cancer will know that certain risk factors — such as increasing age, early onset of womanhood, late onset of menopause and a family history of breast cancer — are completely out of our control. But there are many risk factors, which we can control easily. These ‘controllable’ risk factors readily translate into simple changes that we can all make in our day-to-day lives to help prevent or treat breast cancer. My message is that even advanced breast cancer can be overcome because I have done it.

The first clue to understanding what was promoting my breast cancer came when my husband Peter, who was also a scientist, arrived back from working in China while I was being plugged in for a chemotherapy session.

He had brought with him cards and letters as well as some amazing herbal suppositories sent by my friends and science colleagues in China.

The suppositories were sent to me as a cure for breast cancer. r Despite the awfulness of the situation we both had a good belly laugh and I remember saying that 1 if this was the treatment for breast i cancer in China, then it was little wonder that Chinese women avoided getting the disease. Those words echoed in my mind. Why didn’t Chinese women get breast cancer? I had collaborated 1 with Chinese colleagues on a study of links between soil chemistry and disease, and J remembered some of the statistics.

The disease was virtually non-existent throughout the whole country. On]y one In 10,000 women in China will die from it, compared to that terrible figure of one in 12 in Britain and the even grimmer average of one in 10 across most Western countries.

It is not just a matter of China being a more rural country, with less urban pollution. In high]y urbanised Hong Kong, the rate i uses to 34 women in every 10,000 but still puts the West to shame. 

THE Japanese cities of Hiroshima and Nagasaki have similar rates. And remember, both cities were attacked with nuclear weapons, so in addition to the usual pollution-related cancers, one would also expect to find some radiation-related cases, too. The conclusion we can draw from these statistics strikes you with some force. If a Western woman were to move to industrialised, irradiated Hiroshima, she would stash her risk of contracting breast cancer by half.

Obviously this is absurd. It seemed obvious to me that some lifestyle factor not related to pollution, urbanisation or the environment is seriously increasing the Western woman’s chance of contracting breast cancer.

I then discovered that whatever causes the huge differences in breast cancer rates between oriental and Western countries, it isn’t genetic. Scientific research showed that when Chinese or Japanese people move to the West, within one or two generations their rates of breast cancer approach those of their host community.

The same thing happens when oriental people adopt a completely Western lifestyle m Hong Kong. In fact, the slang name for breast cancer in China translates as ‘Rich Woman’s Disease’. This is because, in China, only the better off can afford to eat what is termed ‘Hong Kong food’.

The Chinese describe all Western food, including everything from ice cream and chocolate bars to spaghetti and feta cheese, as ‘Hong Kong food’ because of its availability in the former British colony and its scarcity, in the past, In mainland China.

 SO IT made perfect sense to me that whatever was causing my breast cancer and the shockingly high incidence in this country generally, it was almost certainly something to do with our better-off, middle-class, Western lifestyle.

There is an important point for men here, too. I have observed in my research that much of the I data about prostate cancer leads I to similar conclusions.

According to figures from the World Health Organisation, the number of men contracting prostate cancer in rural China is negligible, only 0.5 men in every 100,000. In England, Scotland and Wales, however, this figure is 70 times higher.

Like breast cancer, it is a middle-class disease that primarily attacks the wealthier and higher socio-economic groups — those that can afford to eat rich foods.

I REMEMBER saying to my husband- ‘Come on Peter, you have just come back from China. What is it about the Chinese way of life that is so different. Why don’t they get breast cancer?’

We decided to utillse our joint scientific backgrounds and approach it logically. We examined scientific data that pointed us in the general direction of fats in diets

Researchers had discovered in the 1980s that only l4pc of calories in the average Chinese diet were from fat, compared to almost 36pc in the West. But the diet I had been living on for years before I contracted breast cancer was very low in fat and high in fibre.

Besides, I knew as a scientist that fat intake in adults has not been shown to increase risk for breast cancer m most investigations that have followed large groups of women for up to a dozen years.

Then one day something rather special happened. Peter and I have worked together so closely over the years that I am not sure which one of us first said: ‘The Chinese don’t eat dairy produce!’

It is hard to explain to a non-scientist the sudden mental and emotional ‘buzz’ you get when you know you have had an important insight It’s as if you have had a lot of pieces of a jigsaw in your mind.

and suddenly, in a few seconds, they all fall into place and the whole picture is clear.

Suddenly I recalled how many Chinese people were physically unable to tolerate milk, how the Chinese people I had worked with had always said that milk was only for babies, and how one of my close friends, who is of Chinese origin, always politely turned down the cheese course at dinner parties.

I knew of no Chinese people who lived a traditional Chinese life who ever used cow or other dairy food to feed their babies. The tradition was to use a wet nurse but never, ever, dairy products.

Culturally, the Chinese find our Western preoccupation with milk and milk products very strange. I remember entertaining a large delegation of Chinese scientists shortly after the ending of the Cultural Revolution in the 1980s.

On advice from the Foreign Office, we had asked the caterer to provide a pudding that contained a lot of ice cream. After enquiring what the pudding consisted of, au of the Chinese, including their interpreter, politely but firmly refused to eat it and they could not be persuaded to change their minds. At the time we were all delighted and ate extra portions!

MILK, I discovered, is one of the most common causes of food allergies. Over 7Opc of the world’s population are unable to digest the milk sugar, lactose, which has led nutritionists to believe that this is the normal condition for adults, not some sort of deficiency. Perhaps nature is trying to tell us that we are eating the wrong food. Before I had breast cancer for the first time, 1 had eaten a lot of dairy produce, such as skimmed milk, low-fat cheese and yoghurt. I had used it as my main source of protein. I also ate cheap but lean minced beef, which I now realised was probably often ground-up dairy cow.

In order to cope with the chemotherapy I received for my fifth case of cancer, I had been eating organic yoghurts as a way of helping my digestive tract to recover and repopulate my gut with ‘good’ bacteria.

Recently, I discovered that way back in 1989 yoghurt had been implicated in ovarian cancer. Dr Daniel Cramer of Harvard University studied hundreds of women with ovarian cancer, and had them record in detail what they normally ate. I wish I'd been made aware of his findings when he had first discovered them.

FOLLOWING Peter’s and my insight into the Chinese diet, I decided to give up not just yoghurt but all dairy produce immediately. Cheese, butter, milk and yoghurt and anything else that contained dairy produce — it went down sink or in the rubbish It is surprising how many products, including commercial soups, biscuits and cakes, contain some form of dairy produce Even many proprietary brands of margarine marketed as soya, sunflower or olive oil spreads can contain dairy produce I therefore became an avid reader of the small print on food labels. Up to this point;, I had been steadfastly measuring the progress of my fifth cancerous lump with callipers and plotting the results. Despite all the encouraging comments and positive feedback from my doctors and nurses, my own precise observations told me the bitter truth. my first chemotherapy sessions had produced no effect — the lump was still the same size Then I eliminated dairy products. Within days, the Iump started to shrink. About two weeks after my second chemotherapy session and one week after giving up dairy produce, the lump in my neck started to itch. Then i began to soften and to reduce in size. The line on the graph, which had shown no change, was now pointing downwards as the tumour got smaller and smaller.

And, very significantly, I noted that instead of declining exponentially (a graceful curve) as cancer is meant to do, the tumour’s decrease in size was plotted on a straight line heading off the bottom of the graph, indicating a cure: not suppress(on or remission or the tumour.

ONE Saturday afternoon after about six weeks of excluding all dairy produce from my diet, I practised an hour of meditation then felt for what was left of the lump. I couldn’t find it.

Yet I was very experienced at detecting cancerous lumps —I had discovered all five cancers on my own. I went downstairs and asked my husband to feel my neck. He could not find any trace of the lump either.

On the following Thursday I was due to be seen by my cancer specialist at Charing Cross Hospital in London.

He examined me thoroughly, especially my neck where the tumour had been. He was initially bemused and then delighted as he said 1 cannot find it.’ None of my doctors, it appeared, had expected someone with my type and stage of cancer (which had clearly spread to the Iymph system) to survive, let alone be so hale and hearty.

My specialist was as overjoyed as I was. When I first discussed my ideas with him he was understandably sceptical. But I understand that he now uses maps showing cancer mortality in China in his lectures, and recommends a non-dairy diet to his cancer patients.

I now believe that the link between dairy produce and breast cancer is similar to the link between smoking and lung cancer. I believe that identifying the link between breast cancer and dairy produce, and I then developing a diet specifically targeted at maintaining the health of my breast and hormone system, cured me.

It was difficult for me, as it may be for you, to accept that a substance as ‘natural’ as milk might have such ominous health implications. But I an i living proof that it works and, starting from tomorrow, I shall reveal the secrets of my revolutionary action plan.

 Evidence that reveals the

dangers lurking in a pinta

 

JANE PLANT’S conviction that dairy products can cause cancer arises from the complex chemical makeup of milk. All mature breast milk, from humans or other mammals, is a medium for transporting hundreds of chemical components.

It is a powerful biochemical solution, designed specifically to provide for the individual needs of young mammals of the same species. Jane says: "It is not that cow’s milk isn’t a good food. It is a great food— for baby cows. It is not intended by nature for consumption by any species other than baby cows. it Is nutritionally different from human breast milk, containing three times as much protein and far more calcium.’

Breast milk, like cow’s milk, contains chemicals designed to play an important rote i~ the development of young cattle. One of these, insulin growth factor IGF-1,causos cells to divide and reproduce.

IGF-1 is biologically active In humans, especially during puberty, when growth Is rapid. In young girls it stimulates breast tissue to grow and, while its levels are high during pregnancy, the hormones prolactln and oestrogen are also active, enlarging breast tissue and increasing the production of milk ducts in preparation for breast-feeding.

Though the concentration and secretions of these hormones in the blood are small, they exert a powerful effect on the body. All these hormones are present in cow’s milk. IGF-1 is Identical In make-up, whether in human or cow’s milk, but its levels are naturally higher in cow’s milk. It is also found in the meat of cows. High levels of IGF-1 in humans are thought to be a risk factor for breast and prostate cancer. A 1998 study of pre-menopausal women revealed that those with the highest levels of IGF-1 in their bloodstream ran almost three times the risk of developing breast cancer compared with women who had low levels. Among women younger than 50, the risk was increased seven times. Other studies have shown that high circulating levels of IGF-1 In men are a strong Indicator at prostate cancer. Interestingly, recent measures to Improve milk yields have boosted IGF-1 levels in cows. Could IGF-1 tram milk and the

meat of dairy animals cause a build-up in humans, especially over a lifetime, leading to inappropriate cell division? Though we produce our own IGF-1, could it be that the extra amounts we ingest from dairy produce actually cause cancer? Jane Plant already knew that one way the high-profile drug tamoxifen, used in the treatment of breast cancer, Is thought to work Is by lowering circulating levels of IGF-1. 1GF-1 is not destroyed by pasteurisation but critics argue that it is destroyed by digestion and rendered harmless. Jane believes the main milk protein, casein, prevents this from happening and that homogenisation, which prevents milk from separating into milk and cream, could further increase the risk of cancer-promoting hormones and other chemicals reaching the bloodstream. She also believes there are other chemicals in cow’s milk that may be responsible for sending muddied signals to adult tissue. Could prolactln, released to stimulate milk production in cows, have a similar effect on human breast tissue, effectively triggering the same response and causing cells to become confused, stressed and start making mistakes In replicating their own DNA? Studies have confirmed that prolactin promotes the growth of prostate cancer cells in culture. Another hormone, oestrogen, considered one of the main risk factors for breast cancer, is present in milk in minute quantities. But even low levels of hormones are known to cause severe biological damage. Microscopic quantities of oestrogen In our rivers are powerful enough to cause the feminisation of many male species of fish. While oestrogen In milk may not pose a direct threat to tissues, it may stimulate the expression of 1GF-1, resulting in long-term tumour growth. Jane, who has found growing support for her theories from cancer specialists, stresses that she is not setting out to attack more orthodox approaches. She intends her dietary programme to complement the best therapies available from conventional medicine, not to replace them.

Pure but deadly: Is milk potentially fatal?
