According to a new research,Each year, the American Cancer Society estimates the number of new cancer cases and deaths that will occur in the United States, and summarizes the latest data on population-based cancer incidence. Morbidity data (by 2016) were collected by the Surveillance, Epidemiology, and Final Results Program; the National Cancer Registry Program; and the North American Central Cancer Registry Association. Mortality data (up to 2017) were collected by the National Center for Health Statistics. By 2020, 1,806,590 new cancer cases and 606,520 cancer deaths are expected in the United States. The cancer mortality rate has risen until 1991, and then continued to decline to 2017, resulting in an overall decrease of 29%, which means that the number of cancer deaths is estimated to have decreased by 2.9 million compared to the sustained peak. This progress is driven by a long-term decline in the mortality rates of the four major cancers (lung cancer, colorectal cancer, breast cancer, and prostate cancer); however, in the past decade (2008-2017), female breast cancer and the large intestine The rate of decrease in cancer has slowed, while the decrease in prostate cancer has stopped. In contrast, the rate of decline in lung cancer has accelerated, with men falling from 3% per year from 2008 to 2013 to 5% from 2013 to 2017, and women from 2% to almost 4%, stimulating the single The largest annual overall cancer mortality rate fell from 2016 to 2017, a rate of 2.2%. However, the number of deaths caused by lung cancer in 2017 still exceeds breast cancer, prostate cancer, colorectal cancer and brain cancer combined. After the US Food and Drug Administration approved new therapies for metastatic disease, the recent mortality rate of cutaneous melanoma has also decreased significantly. Among men and women around the age of 50, each year from 2006 to 2010 1%, from 7% per year from 2013 to 2010, from 2013 to 2017 to 64 years old, and from 2% to 3% of the 20-49 age group; people aged 65 and over are down by 5% The range of 6% is particularly striking, because the prevalence of this age group is on the rise before 2013. It is worth noting that the long-term rapid increase in liver cancer mortality in women has weakened and stabilized in men. In short, the slowing of certain cancers that are suitable for early detection is tied to the significant benefits of other common cancers.
