Background: Breast cancer remains a leading cause of morbidity and mortality among women in the United States. Previous analyses show that breast cancer incidence increased from 1999 to 2018. The purpose of this article is to examine trends in breast cancer mortality. Methods: Analysis of 1999 to 2020 mortality data from the Centers for Disease Control and Prevention, National Center for Health Statistics, among women by race/ethnicity, age, and US Census region. Results: It was found that overall breast cancer mortality is decreasing but varies by race/ethnicity, age group, and US Census region. The largest decrease in mortality was observed among non‐Hispanic White women, women aged 45 to 64 years of age, and women living in the Northeast; whereas the smallest decrease in mortality was observed among non‐Hispanic Asian or Pacific Islander women, women aged 65 years or older, and women living in the South. Conclusion: This report provides national estimates of breast cancer mortality from 1999 to 2020 by race/ethnicity, age group, and US Census region. The decline in breast cancer mortality varies by demographic group. Disparities in breast cancer mortality have remained consistent over the past two decades. Using high‐quality cancer surveillance data to estimate trends in breast cancer mortality may help health care professionals and public health prevention programs tailor screening and diagnostic interventions to address these disparities.

Plasma cell myeloma (also called multiple myeloma), solitary plasmacytoma, and extramedullary plasmacytoma are primarily diseases of the elderly. Evidence suggests an association between excess body weight and multiple myeloma. Few population‐based studies have examined incidence and mortality of each site in one study. We analyzed incidence and death rates by site (solitary plasmacytoma, extramedullary plasmacytoma, and multiple myeloma) by gender, age, race/ethnicity, and rural‐urban status among adult males and females (aged 20 years or older) in the United States during 2003‐2016. Trends were characterized as average annual percentage change (AAPC) in rates. During 2003‐2016, overall incidence rates among adults were 0.45 for solitary plasmacytoma, 0.09 for extramedullary plasmacytoma, and 8.47 for multiple myeloma per 100,000 persons. Incidence rates for multiple myeloma increased during 2003‐2016 among non‐Hispanic whites (AAPC = 1.78%) and non‐Hispanic blacks (2.98%) 20‐49 years of age; non‐Hispanic whites (1.17%) and non‐Hispanic blacks (1.24%) 50‐59 years of age; and whites non‐Hispanic (0.91%), and non‐Hispanic blacks (0.96%). During 2003‐2016 overall myeloma (extramedullary plasmacytoma and multiple myeloma) death rates among adults was 4.77 per 100,00 persons. Myeloma death rates decreased during 2003‐2016 among non‐Hispanic white (AAPC = −1.23%) and Hispanic (−1.34%) women; and non‐Hispanic white (−0.74%), non‐Hispanic American Indian/Alaska Native (−3.05%) men. The US population is projected to become older and will have a larger proportion of persons who have had an earlier and longer exposure to excess body weight. The potential impact of these population changes on myeloma incidence and mortality can be monitored with high‐quality cancer surveillance data. [ABSTRACT FROM AUTHOR]

Background: Although pediatric cancer mortality and survival have improved in the United States over the past 40 years, differences exist by age, race/ethnicity, cancer site, and economic status. To assess progress, this study examined recent mortality and survival data for individuals younger than 20 years.Methods: Age-adjusted death rates were calculated with the National Vital Statistics System for 2002-2016. Annual percent changes (APCs) and average annual percent changes (AAPCs) were calculated with joinpoint regression. Five-year relative survival was calculated on the basis of National Program of Cancer Registries data for 2001-2015. Death rates and survival were estimated overall and by sex, 5-year age group, race/ethnicity, cancer type, and county-based economic markers.Results: Death rates decreased during 2002-2016 (AAPC, -1.5), with steeper declines during 2002-2009 (APC, -2.6), and then plateaued (APC, -0.4). Leukemia and brain cancer were the most common causes of death from pediatric cancer, and brain cancer surpassed leukemia in 2011. Death rates decreased for leukemia and lymphoma but were unchanged for brain, bone, and soft-tissue cancers. From 2001-2007 to 2008-2015, survival improved from 82.0% to 85.1%. Survival was highest in both periods among females, those aged 15 to 19 years, non-Hispanic Whites, and those in counties in the top 25% by economic status. Survival improved for leukemias, lymphomas, and brain cancers but plateaued for bone and soft-tissue cancers.Conclusions: Although overall death rates have decreased and survival has increased, differences persist by sex, age, race/ethnicity, cancer type, and economic status. Improvements in pediatric cancer outcomes may depend on improving therapies, access to care, and supportive and long-term care. [ABSTRACT FROM AUTHOR]

The article focuses on a study which investigated the cancer incidence rates for a large proportion of the Appalachia population and described the differences in incidence rates between Northern, Central and Southern Appalachia. To calculate age-adjusted rates per 100,000 population and 95 percent gamma confidence limits, SEER*Stat was used. The study revealed that the incidence rates of cancer were higher in Appalachia than in the rest of the U.S.
