Scientists from the London School of Hygiene and Tropical Diseases (London School of Hygiene and Tropical Medicine) and the Universities of Stockholm and Uppsala (University of Uppsala, University of Stockholm) in Sweden found that people who had high birth weight, higher the risk of developing certain forms of cancer, reports BBC News.
That is the conclusion scientists came by examining the medical records 11166 persons born in Sweden from 1915 to 1929. One in four of them developed cancer during the period from 1960 to 2001. The researchers found that the increase in birth weight of 450 grams gave a 17 percent increase in the incidence of lymphomas and 13 per cent increase in the incidence of cancers of the digestive system.
In women who had high birth weight (4 kg or more), 4 times more frequently developed breast cancer before the age of 50 years compared to a "light" newborns. At the same time they have met at least twice as uterine cancer.
The study's authors acknowledge that much of their data calculations — the result of the match. In addition, it is only a certain forms of cancer, rather than incidence as a whole. On the other hand, they note that the likelihood of developing cancer later can influence the conditions in which the fetus is in the womb, in particular the level of hormones in her blood.
According to the medical director of the British Institute of Cancer Research (Cancer Research UK) Professor John Toy (John Toy), the results of the study are quite interesting: if we assume that all calculations are correct, it appears that the likelihood of certain types of cancer is laid in the very early stages of the organism.
