The American authorities have released the next Annual Report to the nation on the state of affairs in the field of cancer (Annual Report to the Nation: Cancer Death Rates Continue to Decline). According to a document published in the Journal of the National Cancer Institute, cancer mortality in the country has been declining in recent years.
The annual report is compiled by the American Cancer Society, the Centers for Disease Control and Prevention (CDC), the National Cancer Institute and the North American Association of Central Cancer Registries.
It contains complete data on the dynamics of morbidity and mortality from cancer in all population groups and their statistical analysis.
According to the document, over the period from 2010 to 2014, cancer mortality decreased by 1.8 percent per year in men, by 1.4 percent in women and by 1.6 percent in children. A decrease in mortality was registered for 11 of the 16 most common malignant tumors in men and 13 of 18 in women, including lung, colon, rectum, breast and prostate cancers. At the same time, mortality from liver cancer (in men and women), pancreas (in men), brain (in men) and uterus increased.
The overall incidence of malignant neoplasms from 2009 to 2013 decreased by 2.3 percent in men and stabilized in women.
Compared to 1975-77, in 2006-12, the five-year survival rate after diagnosis increased for all oncological diseases, except for cervical and uterine body cancer. The largest increase in this indicator (25 percent or more) was recorded for prostate and kidney cancers, as well as non-Hodgkin's lymphomas, myelomas and leukemias.
The lowest five–year survival rate in 2006-12 was observed in pancreatic, liver, lung, esophageal, stomach and brain cancers, and the highest in prostate, thyroid, breast and melanoma cancers.
The report also says that cancer survival varies significantly among people of different ethnicities. For example, the total mortality from all forms of cancer among blacks is 33 percent, and among Indians and Alaska Natives is 51 percent higher than among the white population.
"Cancer mortality in the United States continues to decline. Nevertheless, progress in reducing mortality and increasing survival for some forms of cancer is limited, which indicates the need for intensified work to find new prevention strategies, early detection and treatment, as well as the broad and equitable use of preventive measures with proven effectiveness," the authors of the report conclude.
According to Lisa Richardson, director of the CDC's Cancer Prevention and Control Department, the most important cancer prevention strategies remain the fight against smoking and overweight.
In 2016, Oxford University researchers found that malignant tumors came out on top in the structure of male mortality in 12 Western European countries. Worldwide, cardiovascular diseases remain the main cause of death, cancer ranks second.
