One out of  nine women in the United  States will develop breast cancer in her  lifetime. In fact, it is the second leading cause of cancer death for women  (after lung cancer) and the leading overall cause of death in women between the  ages of forty and fifty-five. For too long women have erroneously believed that  there is little or nothing they can do to prevent this dread illness. Our major  medical efforts are directed toward detecting and treating, rather than  preventing, breast cancer. Professor  Jane Plant, one of Britain's most eminent scientists,  contracted breast cancer in 1987. She had five recurrences, and, by 1993, the  cancer had spread to her lymph system. When orthodox medicine gave up and she  was told that she only had three months to live, she determined to use her  extensive scientific training and her knowledge of other cultures to find a way  to survive. In her research, she was startled to find that in  China breast cancer affects far fewer  women than in Western countries. Plant considered that there could be a dietary  trigger for the illness. As she continued her scientific investigations, she  became convinced that there was a causal link between consumption of dairy  products and breast cancer. Jane Plant finally defeated her breast cancer, in  part because she used her training and knowledge as a natural scientist to  understand it-- and then overcome it. Combining the diet her research had led to  with traditional medical treatment, Professor Plant was not only able to triumph  over her own disease but also to pass on what she had discovered to help more  than sixty other women successfully fight their breast cancer. In this book,  women will be presented for the first time with a compelling body of evidence  strongly suggesting that consumption of dairy products may cause breast cancer.  It will demonstrate the specific changes that women can make in their day-to-day  lives to help prevent and treat breast cancer. With a clear statement of the  scientific principles behind her discovery, Professor Plant includes detailed  suggestions for ways to alter your diet by eliminating or reducing consumption  of many suspected cancer-causing agents, especially dairy products, and  replacing them with healthful alternatives. She offers as well detailed menus  and recipes to help you make the transition and enjoy it. “Life  In Your Hands” is a revolutionary book that will change the lives of  millions of women.
 “Why I believe that giving  up milk is the key to beating cancer...”
 [Extracted  from Your Life in Your Hands by Professor  Jane Plant]
 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. I 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.  Despite  the awfulness of the situation, we both had a good belly laugh, and I remember  saying that this was the treatment for breast 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 in China get breast cancer? I had  collaborated once with Chinese colleagues on a study of links between soil  chemistry and disease, and I remembered some of the statistics. 
 The  disease was virtually non-existent throughout the whole country. Only 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 highly  urbanized Hong Kong, the rate rises 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 industrialized, irradiated Hiroshima, she would slash  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,  urbanization 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 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  in 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, has 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 data about prostate cancer leads to  similar conclusions. According to figures from the World Health Organization,  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 utilize 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 l4% of calories in the  average Chinese diet were from fat, compared to almost 36% 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 fiber. Besides, I knew as a scientist that fat intake in  adults has not been shown to increase risk for breast cancer in 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 inquiring what the pudding consisted of, all 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 70% of the  world’s population is 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, I had eaten a lot of  dairy produce, such as skimmed milk, low-fat cheese and yogurt. I had used it as  my main source of protein. I also ate cheap but lean minced beef, which I now  realized 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  yogurts 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 yogurt 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 wished  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 the 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 calipers 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 lump 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 it began to soften and  to reduce in size. The line on the graph, which had shown no change, was now  pointing downwards as the tumor got smaller and smaller. And, very  significantly, I noted that instead of declining exponentially (a graceful  curve) as cancer is meant to do, the tumor’s decrease in size was plotted on a  straight line heading off the bottom of the graph, indicating a cure, not  suppression (or remission) of the tumor. 
 One  Saturday afternoon after about six weeks of excluding all dairy produce from my  diet, I practiced 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 tumor had been. 
 He was  initially bemused and then delighted as he said, “I 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 lymph 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 skeptical. 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 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 am a living proof  that it works and, starting from tomorrow, I shall reveal the secrets of my  revolutionary action plan.
