U.S. study detected a change in the incidence of liver cancer in the world, it revealed a rise in more developed countries, despite the low risk factors compared with other countries.
The study, carried out with the participation of the American Cancer Society that liver cancer rates increased in areas less serious, in terms of incidence of this type of cancer, such as North America, while it decreased in areas that show a higher risk for the spread of the disease, such as Asia.
The researchers used were made by the International Agency for Research on Cancer and the American Cancer Society to examine recent trends for the incidence of liver cancer in 32 cancer registries in different parts of the world, during the period between 1993 and 2002.
According to the results of the study published by "periodic vital signs of Cancer Epidemiology and Prevention" that the incidence of liver cancer in women and men have risen in eight of the cancer registries included in the study.
According to the results, only the high incidence of liver cancer, largely on the economically developed countries, one of the least dangerous to the spread of the disease, such as Western Europe and North America and Oceania.
The researchers attributed this rise - in part - to the increase in cases of hepatitis "C" due to chronic lack of screening donated blood and the use of contaminated needles for medical purposes, and the widespread injecting drug use in the past decades.
On the other hand the study showed that the incidence of liver cancer in both sexes declined in five of the records of the cancer - three of them in Asia - although these rates remain high for the equivalent of about three to four times what is being observed in areas that have low risk factors.
The researchers concluded that liver cancer rates continue to rise in some parts of the world's least dangerous, while the now declining in some countries that have the greatest risk factors in the continent of Asia.
The researchers hope the study can contribute in stimulating the implementation of studies to clarify more about the causes of the differences associated with the emergence of liver cancer on a global level.
