Study: a decrease in the number of deaths due to lung cancer

In a recent study conducted by researchers from the Silvertter Comprehensive Cancer Center, attached to the University of Miami, in collaboration with other organizations, it revealed a noticeable decrease in deaths associated with the trachea, bronchi and lung in the ten largest countries in terms of population during the period of 1990 to 2019. to reduce these deaths. The study published in the journal “A Clinical Medicen” relied on data from the Global Burden database of disease; The study found that a 8% decrease in the deaths associated with these cancers over the past three decades. Despite the decline in tobacco deaths, it is still the largest percentage of cases. On the other hand, the deaths associated with air pollution have increased worldwide, and exposure to asbestos is a major concern, especially in the United States. The lead author of the study “Gilberto Lopez” and head of the medical oncology section in the Sylvester Center emphasized the importance of this research in assessing the world trends and identifying areas that need general health policies and additional research to combat respiratory cancers. The death rate associated with the respiratory system lines caused by the use of tobacco dropped from 72% in 1990 to 66% in 2019. Despite this decline, some countries such as China and Indonesia are still an increase in tobacco deaths. The death figures among women have risen by 2% in the world, while men still make up about three -quarters of tobacco deaths. Air pollution represents about 20% of the global deaths associated with bronchial and lung cancer. While the deaths associated with pollution generally decreased from 1990 to 2019, the microcal -related deaths (PM 2.5) increased by 11%. The death rates in China were twice the world average. Despite the ban of asbestos – a natural metal consisting of very small and thin fibers that can be easily inhaled used in the past in the past – in the United States, the related deaths remain almost twice the world average. The researchers emphasized the need to investigate more asbestos the reasons for exposure to asbestos, especially in work environments. The study highlights the importance of continuing to seek a better understanding of mechanisms that lead to breathing cancer, and how different risk factors affect molecular changes in cancer cells. It also emphasized that it is necessary to revise the current investigative guidelines, which focus mainly on tobacco, while increasing the diagnosis of cancer in young people, especially women with low tobacco.
