The ancient people were immune to cancer

In today’s world the frequency of appearance of cancer 100 times greater than in the past. To such conclusion the canadian scientists who examined the remains of thousands of ancient Egyptians and described only a few cases of malignant tumors. Article researchers published in the International Journal of Paleopathology.

Древние люди оказались невосприимчивыми к раку

The skeletons and their fragments with traces of malignant tumors were found in the cemeteries of Tirgu ain (Ain Tirghi) and of kellis (Kellis) in the Dakhla oasis, whose age has been established by the radiocarbon Dating was 2800-3000 and 1550-1950 years respectively. There are about 1,800 of the remains, but only 1087 of them are quite well preserved for morphological analysis of the bones. The gender of the people was established on the basis of the shape and size of the skull, and age on the degree of tooth decay and other characteristics, including the shape of the ribs and even the mummified genitals.

On the bones were discovered damages which are typical for the development of malignant tumors. So, the skeleton of a man who died at the age of approximately 30 years, had traces of bone lesions in the right scapula, humerus, hip and vertebrae typical of metastatic carcinoma. Scientists believe that he suffered from testicular cancer. The skull women 20 years of age revealed numerous injuries of varying size, which probably emerged due to cervical cancer. Other cases included a woman approximately 50 years of age, who died of cancer; a man of 50-60 years with rectal cancer, 3-5-year-old child with acute leukemia (or, less likely, neuroblastoma) and a young woman with cervical cancer.

According to researchers, the most correct measure for comparing the prevalence of malignant diseases in the past and at present is the risk of cancer in a person’s life (lifetime cancer risk LTCR). In modern Western countries it is approximately 50 percent (500 of 1000), and the risk of death from the disease to 25 percent. This estimate is based on total number of new cases of the appearance of malignant tumors in the course of the year, as well as mortality. In ancient Dakhla LTCR was 0.5 percent (5 out of 1000 people). At the same time, this statistic does not account for tumors not involving the bone.

However, scientists tend to believe that the environment in the modern world is more carcinogenic than in the past. The factors that contribute to disease, include tobacco Smoking, alcohol consumption, high maintenance in food of carbohydrates and fats, as well as polluted air.
