The conversation in the desert

The members of the expedition are tired. Difficult months of hard work. Sultriness. Dust, sand dust, which crunches on the teeth, hits the ears, from which it is impossible to get even on a calm day. And so many impressions! Hidden for thousands of years in the depth of this hot soil appeared to the eyes of man. For the Egyptian was a matter of paramount importance to ensure its ashes at rest and full integrity. And only now, after four thousand years, this rest violated.
The finds have huge scientific value. Years will need to explore all that found in the tombs of ancient Egyptian kings.
Evening. At the entrance to the tent sitting scientific workers of the expedition.
"Well, doctor, what gave an x-ray? - Head of the expedition, a famous archaeologist, very far from medical interests, but this question interested him.
- The results are obvious. It's sarcoma of the bone. .
- Sarcoma? What is this disease?
Is the same as cancer. When the tumor affects one type of tissue, it is called cancer, and when the other sarcoma. Cancer is a tumor top and glandular tissue, I sarcoma is a growth of connective tissue and those tissues which it happen, muscles, and bones.
"But correct this diagnosis?
Doubts may not be. X-rays were sent largest specialists. They all confirm this diagnosis.
- So, this young Egyptian Pharaoh, who lived about 4 thousand years ago, died of sarcoma? Do tumor struck the people in those times, like now, in the nineteenth century? The archeologist did not hide his surprise.
- Yes, he died of sarcoma hips. There is much evidence that cancer exists Millennium. In the ebers papyrus, the duration of which is estimated 1500 years BC, described cancer. Any such tumors in question and the ancient poets. Hippocrates, the greatest physician of antiquity knew cancer and even have divided them into several groups.
- Why, in fact, these diseases are called cancer? Although in your ancient science many oddities,archaeologist smiled a little, " but who came up with the strange idea to name the tumor cancer?
- Yes, indeed, the majority of tumors any resemblance with cancer has not. But some skin tumors resemble the image of a marine cancer the crab,a doctor had to draw something of a stick on the sand - they form the points that with a little imagination can be taken for claws.
- Probably with very large imagination, which, unfortunately, is inherent in modern doctors.
- And why unfortunately? Without imagination unthinkable scientific progress. Further accumulation of facts must always cast imperfect theory, in which the imagination captivated too far from the facts.
- And what theories exist on the origin of cancer and, more importantly, s what facts they are coming from?
"Oh, shortage of theories not. The most likely now is the theory of the lost cells.
- Lost cells? What does it mean?
- When an egg to form an embryo, all its tissues, muscles, to STI, leather and others formed from certain strata of germ cells.
But imagine that germ cells, "C which will be formed, for example, the skin will become more than you need. Then part of them will remain unused and can get into other tissues. These "lost" cells for a long time do not make themselves known. But they remain alive and under the influence of the different reasons can >start to multiply. Thus arises the tumor.
"Maybe that's not so, " said archaeologist,in this theory too much imagination. Why embryonic cells produce more than you need, why they are in other tissues, why for years and decades they do not make themselves felt, and then suddenly begin to multiply? Indeed, there are more "why"than "because".
- You are right, of course, " the doctor was a little embarrassed, - it is necessary to wait, when the study of cancer will respond to all these "why".
- Perhaps we'll have to wait for a long time, " smiled archaeologist. - And now let's go to bed.
All went into the tent. A light breeze lifted into the air clouds of sand, as well as thousands of years ago, when Pharaoh, who died of sarcoma, reigned on earth.

  • Is it possible to vaccinate the tumor?
