There are limited published data on recent cancer incidence and mortality trends worldwide. We used the International Agency for Research on Cancer's CANCERMondial clearinghouse to present ...age-standardized cancer incidence and death rates for 2003-2007. We also present trends in incidence through 2007 and mortality through 2012 for select countries from five continents. High-income countries (HIC) continue to have the highest incidence rates for all sites, as well as for lung, colorectal, breast, and prostate cancer, although some low- and middle-income countries (LMIC) now count among those with the highest rates. Mortality rates from these cancers are declining in many HICs while they are increasing in LMICs. LMICs have the highest rates of stomach, liver, esophageal, and cervical cancer. Although rates remain high in HICs, they are plateauing or decreasing for the most common cancers due to decreases in known risk factors, screening and early detection, and improved treatment (mortality only). In contrast, rates in several LMICs are increasing for these cancers due to increases in smoking, excess body weight, and physical inactivity. LMICs also have a disproportionate burden of infection-related cancers. Applied cancer control measures are needed to reduce rates in HICs and arrest the growing burden in LMICs.

There are striking disparities in the global cancer burden in women, yet few publications highlight cancer occurrence in this population, particularly for cancers that are not sex specific. This ...article, the first in a series of two, summarizes the current burden, trends, risk factors, prevention, early detection, and survivorship of all cancers combined and seven sites (breast, cervix, uterine corpus, ovary, colorectum, lung, and liver) that account for about 60% of the cancer burden among women worldwide, using data from the International Agency for Research on Cancer. Estimated 2012 overall cancer death rates in general are higher among women in low- and middle-income countries (LMICs) than high-income countries (HICs), despite their lower overall incidence rates, largely due to inadequate access to early detection and treatment. For example, the top mortality rates are in Zimbabwe (147 deaths per 100,000) and Malawi (138). Furthermore, incidence rates of cancers associated with economic development (e.g., lung, breast, colorectum) are rising in several LMICs. The burden of cancer among women could be substantially reduced in both HICs and LMICs through broad and equitable implementation of effective interventions, including tobacco control, HPV and HBV vaccination, and screening (breast, cervix, and colorectum).
While incidence and mortality rates for most cancers (including lung, colorectum, female breast, and prostate) are decreasing in the United States and many other western countries, they are ...increasing in several less developed and economically transitioning countries because of adoption of unhealthy western lifestyles such as smoking and physical inactivity and consumption of calorie-dense food. Indeed, the rates for lung and colon cancers in a few of these countries have already surpassed those in the United States and other western countries. Most developing countries also continue to be disproportionately affected by cancers related to infectious agents, such as cervix, liver, and stomach cancers. The proportion of new cancer cases diagnosed in less developed countries is projected to increase from about 56% of the world total in 2008 to more than 60% in 2030 because of the increasing trends in cancer rates and expected increases in life expectancy and growth of the population. In this review, we describe these changing global incidence and mortality patterns for select common cancers and the opportunities for cancer prevention in developing countries.
IMPORTANCE: Prostate cancer incidence in men 75 years and older substantially decreased following the 2008 US Preventive Services Task Force (USPSTF) recommendation against prostate-specific antigen ...(PSA)–based screening for this age group. It is unknown whether incidence has changed since the USPSTF recommendation against screening for all men in May 2012. OBJECTIVE: To examine recent changes in stage-specific prostate cancer incidence and PSA screening rates following the 2008 and 2012 USPSTF recommendations. DESIGN AND SETTINGS: Ecologic study of age-standardized prostate cancer incidence (newly diagnosed cases/100 000 men aged ≥50 years) by stage from 2005 through 2012 using data from 18 population-based Surveillance, Epidemiology, and End Results (SEER) registries and PSA screening rate in the past year among men 50 years and older without a history of prostate cancer who responded to the 2005 (n = 4580), 2008 (n = 3476), 2010 (n = 4157), and 2013 (n = 6172) National Health Interview Survey (NHIS). EXPOSURES: The USPSTF recommendations to omit PSA-based screening for average-risk men. MAIN OUTCOMES AND MEASURES: Prostate cancer incidence and incidence ratios (IRs) comparing consecutive years from 2005 through 2012 by age (≥50, 50-74, and ≥75 years) and SEER summary stage categorized as local/regional or distant and PSA screening rate and rate ratios (SRRs) comparing successive survey years by age. RESULTS: Prostate cancer incidence per 100 000 in men 50 years and older (N = 446 009 in SEER areas) was 534.9 in 2005, 540.8 in 2008, 505.0 in 2010, and 416.2 in 2012; rates began decreasing in 2008 and the largest decrease occurred between 2011 and 2012, from 498.3 (99% CI, 492.8-503.9) to 416.2 (99% CI, 411.2-421.2). The number of men 50 years and older diagnosed with prostate cancer nationwide declined by 33 519, from 213 562 men in 2011 to 180 043 men in 2012. Declines in incidence since 2008 were confined to local/regional-stage disease and were similar across age and race/ethnicity groups. The percentage of men 50 years and older reporting PSA screening in the past 12 months was 36.9% in 2005, 40.6% in 2008, 37.8% in 2010, and 30.8% in 2013. In relative terms, screening rates increased by 10% (SRR, 1.10; 99% CI, 1.01-1.21) between 2005 and 2008 and then decreased by 18% (SRR, 0.82; 99% CI, 0.75-0.89) between 2010 and 2013. Similar screening patterns were found in age subgroups 50 to 74 years and 75 years and older. CONCLUSIONS AND RELEVANCE: Both the incidence of early-stage prostate cancer and rates of PSA screening have declined and coincide with 2012 USPSTF recommendation to omit PSA screening from routine primary care for men. Longer follow-up is needed to see whether these decreases are associated with trends in mortality.
The American Cancer Society, Centers for Disease Control and Prevention, National Cancer Institute, and North American Association of Central Cancer Registries collaborate to provide annual updates ...on cancer incidence and mortality and trends by cancer type, sex, age group, and racial/ethnic group in the United States. In this report, we also examine trends in stage-specific survival for melanoma of the skin (melanoma).
Incidence data for all cancers from 2001 through 2017 and survival data for melanoma cases diagnosed during 2001-2014 and followed-up through 2016 were obtained from the Centers for Disease Control and Prevention- and National Cancer Institute-funded population-based cancer registry programs compiled by the North American Association of Central Cancer Registries. Data on cancer deaths from 2001 to 2018 were obtained from the National Center for Health Statistics' National Vital Statistics System. Trends in age-standardized incidence and death rates and 2-year relative survival were estimated by joinpoint analysis, and trends in incidence and mortality were expressed as average annual percent change (AAPC) during the most recent 5 years (2013-2017 for incidence and 2014-2018 for mortality).
Overall cancer incidence rates (per 100 000 population) for all ages during 2013-2017 were 487.4 among males and 422.4 among females. During this period, incidence rates remained stable among males but slightly increased in females (AAPC = 0.2%, 95% confidence interval CI = 0.1% to 0.2%). Overall cancer death rates (per 100 000 population) during 2014-2018 were 185.5 among males and 133.5 among females. During this period, overall death rates decreased in both males (AAPC = -2.2%, 95% CI = -2.5% to -1.9%) and females (AAPC = -1.7%, 95% CI = -2.1% to -1.4%); death rates decreased for 11 of the 19 most common cancers among males and for 14 of the 20 most common cancers among females, but increased for 5 cancers in each sex. During 2014-2018, the declines in death rates accelerated for lung cancer and melanoma, slowed down for colorectal and female breast cancers, and leveled off for prostate cancer. Among children younger than age 15 years and adolescents and young adults aged 15-39 years, cancer death rates continued to decrease in contrast to the increasing incidence rates. Two-year relative survival for distant-stage skin melanoma was stable for those diagnosed during 2001-2009 but increased by 3.1% (95% CI = 2.8% to 3.5%) per year for those diagnosed during 2009-2014, with comparable trends among males and females.
Cancer death rates in the United States continue to decline overall and for many cancer types, with the decline accelerated for lung cancer and melanoma. For several other major cancers, however, death rates continue to increase or previous declines in rates have slowed or ceased. Moreover, overall incidence rates continue to increase among females, children, and adolescents and young adults. These findings inform efforts related to prevention, early detection, and treatment and for broad and equitable implementation of effective interventions, especially among under resourced populations.
To characterize the experience and impact of pandemic-related workplace violence in the form of harassment and threats against public health officials.
We used a mixed methods approach, combining ...media content and a national survey of local health departments (LHDs) in the United States, to identify harassment against public health officials from March 2020 to January 2021. We compared media-portrayed experiences, survey-reported experiences, and publicly reported position departures.
At least 1499 harassment experiences were identified by LHD survey respondents, representing 57% of responding departments. We also identified 222 position departures by public health officials nationally, 36% alongside reports of harassment. Public health officials described experiencing structural and political undermining of their professional duties, marginalization of their expertise, social villainization, and disillusionment. Many affected leaders remain in their positions.
Interventions to reduce undermining, ostracizing, and intimidating acts against health officials are needed for a sustainable public health system. We recommend training leaders to respond to political conflict, improving colleague support networks, providing trauma-informed worker support, investing in long-term public health staffing and infrastructure, and establishing workplace violence reporting systems and legal protections.

IMPORTANCE: A systematic and comprehensive evaluation of long-term trends in mortality is important for health planning and priority setting and for identifying modifiable factors that may contribute ...to the trends. OBJECTIVE: To examine temporal trends in deaths in the United States for all causes and for 6 leading causes. DESIGN, SETTING, AND PARTICIPANTS: Joinpoint analysis of US national vital statistics data from 1969 through 2013. EXPOSURE: Causes of death. MAIN OUTCOMES AND MEASURES: Total and annual percent change in age-standardized death rates and years of potential life lost before age 75 years for all causes combined and for heart disease, cancer, chronic obstructive pulmonary disease (COPD), stroke, unintentional injuries, and diabetes mellitus. RESULTS: Between 1969 and 2013, the age-standardized death rate per 100 000 decreased from 1278.8 to 729.8 for all causes (42.9% reduction; 95% CI, 42.8%-43.0%), from 156.8 to 36.0 for stroke (77.0% reduction; 95% CI, 76.9%-77.2%), from 520.4 to 169.1 for heart disease (67.5% reduction; 95% CI, 67.4%-67.6%), from 65.1 to 39.2 for unintentional injuries (39.8% reduction; 95% CI, 39.3%-40.3%), from 198.6 to 163.1 for cancer (17.9% reduction; 95% CI, 17.5%-18.2%), and from 25.3 to 21.1 for diabetes (16.5% reduction; 95% CI, 15.4%-17.5%). In contrast, the rate for COPD increased from 21.0 to 42.2 (100.6% increase; 95% CI, 98.2%-103.1%). However, during the last time segment detected by joinpoint analysis, death rate for COPD in men began to decrease and the declines in rates slowed for heart disease, stroke, and diabetes. For example, the annual decline for heart disease slowed from 3.9% (95% CI, 3.5%-4.2%) during the 2000-2010 period to 1.4% (95% CI, −3.4% to 0.6%) during the 2010-2013 period (P = .02 for slope difference). Between 1969 and 2013, age-standardized years of potential life lost per 1000 decreased from 1.9 to 1.6 for diabetes (14.5% reduction; 95% CI, 12.6%-16.4%), from 21.4 to 12.7 for cancer (40.6%; 95% CI, 40.2%-41.1%), from 19.9 to 10.4 for unintentional injuries (47.5%; 95% CI, 47.0%-48.0%), from 28.8 to 9.1 for heart disease (68.3%; 95% CI, 68.1%-68.5%), and from 6.0 to 1.5 for stroke (74.8%; 95% CI, 74.4%-75.3%). For COPD, the rate for years of potential life lost did not decrease over this time interval. CONCLUSIONS AND RELEVANCE: According to death certificate data between 1969 and 2013, an overall decreasing trend in age-standardized death rate was observed for all causes combined, heart disease, cancer, stroke, unintentional injuries, and diabetes, although the rate of decrease appears to have slowed for heart disease, stroke, and diabetes. The death rate for COPD increased during this period.
Background
The American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries collaborate to ...provide annual updates on cancer occurrence and trends in the United States.
Methods
Data on new cancer diagnoses during 2001 through 2016 were obtained from the Centers for Disease Control and Prevention‐funded and National Cancer Institute‐funded population‐based cancer registry programs and compiled by the North American Association of Central Cancer Registries. Data on cancer deaths during 2001 through 2017 were obtained from the National Center for Health Statistics' National Vital Statistics System. Trends in incidence and death rates for all cancers combined and for the leading cancer types by sex, racial/ethnic group, and age were estimated by joinpoint analysis and characterized by the average annual percent change during the most recent 5 years (2012‐2016 for incidence and 2013‐2017 for mortality).
Results
Overall, cancer incidence rates decreased 0.6% on average per year during 2012 through 2016, but trends differed by sex, racial/ethnic group, and cancer type. Among males, cancer incidence rates were stable overall and among non‐Hispanic white males but decreased in other racial/ethnic groups; rates increased for 5 of the 17 most common cancers, were stable for 7 cancers (including prostate), and decreased for 5 cancers (including lung and bronchus lung and colorectal). Among females, cancer incidence rates increased during 2012 to 2016 in all racial/ethnic groups, increasing on average 0.2% per year; rates increased for 8 of the 18 most common cancers (including breast), were stable for 6 cancers (including colorectal), and decreased for 4 cancers (including lung). Overall, cancer death rates decreased 1.5% on average per year during 2013 to 2017, decreasing 1.8% per year among males and 1.4% per year among females. During 2013 to 2017, cancer death rates decreased for all cancers combined among both males and females in each racial/ethnic group, for 11 of the 19 most common cancers among males (including lung and colorectal), and for 14 of the 20 most common cancers among females (including lung, colorectal, and breast). The largest declines in death rates were observed for melanoma of the skin (decreasing 6.1% per year among males and 6.3% among females) and lung (decreasing 4.8% per year among males and 3.7% among females). Among children younger than 15 years, cancer incidence rates increased an average of 0.8% per year during 2012 to 2016, and cancer death rates decreased an average of 1.4% per year during 2013 to 2017. Among adolescents and young adults aged 15 to 39 years, cancer incidence rates increased an average of 0.9% per year during 2012 to 2016, and cancer death rates decreased an average of 1.0% per year during 2013 to 2017.
Conclusions
Although overall cancer death rates continue to decline, incidence rates are leveling off among males and are increasing slightly among females. These trends reflect population changes in cancer risk factors, screening test use, diagnostic practices, and treatment advances. Many cancers can be prevented or treated effectively if they are found early. Population‐based cancer incidence and mortality data can be used to inform efforts to decrease the cancer burden in the United States and regularly monitor progress toward goals.
