It was not until
1970 that we realized the magnitude of the problems created by Agent Orange. Through the victims of Agent Orange who came to us from the South and through other reports we came to realize that in the
Long Dien area, for example, Agent Orange had caused miscarriages to human beings as well as to cattle and water buffaloes. Even pigs aborted, and hens laying no more eggs. All these caused me to think and to investigate further into the problem. We conducted a statistical study of the patients who came to us from the South and found out high incidents of miscarriages and deformed stillborn babies, known as “monster fetuses”. In
1970 when we first called attention to this problem at a conference in
Paris people attacked us as being unscientific. Some
said that this was only anti-American propaganda. Later, in
1972, a first-class Vietnamese scientist and another member of the royal family,
Buu Hoi, and I found out that Agent Orange was very similar to an agent which created cancer. So we focused our attention on the problem of cancer and found out that among the ammunition transporting units returning fro the South there were high incidents of liver cancer. We found out that Agent Orange, in particular the dioxin, acted as a carcinogen. Therefore, in
1972 in a conference in
Copenhagen, we brought attention to the fact that dioxin was probably carcinogenic. Foreign scientists at that time said that we were only spreading anti-US propaganda and that we were only kidding them. But subsequent experiments on animals made people realize that there was indeed some
problem. And recent studies made by
Swedish and West German scientists have revealed that there is a marked difference in the incidence of cancer in a controlled group of patients who had been exposed to Agent Orange and those who had not. Therefore, although people rejected our original hypotheses based on observations of our patients, eventually they realize that the problems created by Agent Orange are present not only in Vietnam but also in the United States and in
Australia. It is clear from empirical studies that there is a problem. However, people say that this is not enough. They say that you must have experiment made on human beings. But this is very difficult because such experiment on human beings is quite complicated. Furthermore, in order to obtain a valid study on human beings you need to conduct experiments on as many as ten thousand persons. This is clearly beyond the ability and means of us in
Vietnam at the present time. However, as we are conducting studies at the present time, we have found that Vietnamese soldiers who have come home to the North from the South and who have gotten married, have fathered high incidents of deformed babies. The wives of these soldiers have also shown high incidents of miscarriages and of giving birth to stillborn babies. We have seen the same symptoms on Vietnamese soldiers which have been found on American GI’s who had been exposed to Agent Orange. I am sure there is the same problem in
Australia. I have recently read an article in The Journal of American Medical Association in which an American doctor claims that of the 87 American GI’s studied, the incidents of miscarriages were 16%, which are really high because we have often observed that incidents of miscarriages are normally about 3.5% at the highest. Hence, there is a real problem here. But it is no easy task to
try and prove this.
