Graduated early from the Medical College of Geneva University, Switzerland, Dr Huang Youpeng, has more than 30 years’ experience of the research in immunology and tumor. In the field of immune in our country at present, he is an overseas expert with much influence. Recently, he was talking about the prevention and treatment of cancer in the western world, the contents are quite refreshing. Different nutrition and the relationship between tumor.
Relations between different nutrition and tumor
　In a television news report, Professor Huang saw a more than 80-year-old patient took the tumor resection surgery in hospital. He saw an 87 years old veteran cadres had chemotherapy in a well-known hospital in Beijing, where he exchanges with the experts there.  He asked: "Why should the patient take chemotherapy, as he is in such a great age?" They said: "He must take the chemotherapy." Professor Huang was very confused with this. He said that if the patient's tumor is in the long spray doors, and unable to eat anything, this affects the quality of his life, that he must take the surgery. But as we autopsy the people died before the age of 80, we will find that 100% of them have tumors.  Professor Huang said that, in Europe, doctors must emphasize doing basic research, we must have a scientific thinking ability, and there advocates to be "the scientist-doctor", not to be a philistine medical Carpenter.
Why do people have tumor
　Currently in the world for cancer therapy, there will always be a misunderstanding: Focus on tumor itself; think about ways to kill it. Use radiotherapy and chemotherapy technology to kill the tumor virus, this result in Killing many healthy cells of the human body. At the same time, however, no longer consider why people have tumor.
　In replication process the mutations come out, this is conducive to the evolution of species, and it is the inevitable thing in the process of replication that errors happened, tumor arises as the cause of gene mutations. The evolution of species is the basis of gene mutation. But this will bring out a by-product: the growth of malignant tumors. This is the price must be paid in the human evolution. It is impossible to eradicate tumor. The come out of the tumor cells is in the mechanism of the biological aging. It is impossible for the natural world to have a biological, longevity immortality, a perennial. This is the Effect of the nature’s control and balance mechanism. People’s immune dysfunction, tumor comes out, and then died, this has a positive sense in the human’s evolution, and that is why human has tumor.
The older the slower risk there is
　Tumor Association of the United States announced in 2001, do not advocate the chemotherapy and radiotherapy for the patients over the age of 60 has malignant tumor.  For the older the slower risk there is for the malignant tumors. The immunity is weaker for the elderly, and they could not tolerate with radiotherapy and chemotherapy for they could destruct massive immune cells. Radiotherapy and chemotherapy generally only shorten their survival time. But now in our country, hospitals advocate patients over the age of 60 take radiotherapy and chemotherapy. Professor Huang is very puzzled. Professor Huang read statistical information abroad, compared the liver transplants patients and chemotherapy and radiotherapy patients, through the treatment group and the non-treated group, the non-treatment group has three time more survival period than the treated group and quality of life for them also higher.
　Professor Huang said that, we have dealt with tumor too extreme, one-sided and did not take into deep account why people have tumor. Provided that people can live to 120 years old, there will be 3-4 malignant tumors in his body, but they will not affect people's quality of life. The older the people grow, the lower the level of malignant tumor would be, and the lower the risk there is. It is the pathological for people to have tumor before the age of 70. And the tumor is physiological tumor, has no pathological significance after the age of 70. We should not be afraid of cancer, and should face with it in a scientific way.  Do not treat it as one-sided and abhorrence things, this is not the correct concept. The tumor is a piece of meat in the body of the person, a cell organizations, it also has its own desire to survive. We should take method to recognize it, and do not let it happens to us too early. It is physiological phenomenon for a person to have tumor in the older age, it is normal, and could be ignored. But we should delay its come out and development, and have effective control over it.
Most patients are scared to death
　The occurrence of tumor, is a normal biological evolution process, each person is probably to have a tumor. The growth of the tumor cell is slow, and will not kill people in a few days, a few months or even a few years. This is a chronic process of attrition.  Coronary heart disease would cause sudden death, but tumor would not. Most of the tumor patients are scared to death, for it caused fear, sadness, depression, the collapse of the immune system, endocrine disorders. The main reasons for this situation, scared to death, is for that people do not have an objective understanding on tumor.
　Our cancer experts did not tell this information to all, and they had great fear of Tumor for the ignorance of it. Patients could be having lived for more time died. When in Europe,  Professor Huang took 200 cases autopsy annually, all of them are people over 75 years old, the cause of death was diabetes, coronary heart disease, stroke, and so on. They had no cancer symptoms, the results of autopsy showed that 48% of the people had 1 or 2 malignant tumors in vivo, and some were big.
　People with old age would have more opportunity of the incidence of tumor. However, this has not affected their quality of life, things that affected are those metabolic syndrome, the cause of death are these diseases. They have not known that their got tumor, and there is no spirit of fear and tremendous pressure. Foreigners also very scared of the cancer. In fact, the risk of cancer is found too late, once found it will be difficult to cure.  This caused people great fear.
Temporary or permanent cure
　Human tumor is ultimately defeated in the area of prevention. As the traditional methods of treatment simply to cut it, radiate it to death, to eradicate cancer, is a one-sided view. The whole world against cancer, has over 50 years’ history, had spent a huge amount of funds, but the number of the patients with tumors did not decrease, but more and more. Today, the way we deal with tumors, is like the police catch the thief, once find it, we must eradicate it. This is the temporary treatment. If we could eradicate the "crime" of "social environment", could we avoid a large number of "criminals".
　Prevention and monitoring the mutations of the tumor cell, is the way to prevent the "crime" before his approach. If early detected, and improve the body's overall immune system, use the thymosin extract substances, such as amino acids, increased cell immunity, will us be able to deal more effectively with tumor. There is a rare element, selenium, it can make tumor cells directly collapse. Chinese medicine the Cordyceps sinensis, Ganoderma lucidum have markedly effect of increasing the immunity. It is the latest concept for the prevention and treatment of the tumor in the world. This is the permanent cure.
