Abstract A081: Comprehensive examination of disparities in cancer incidences by race, gender, and age over 65 years in Alabama's Black belt counties, USA

Abstract

Abstract In the United States, significant disparities persist in cancer incidence, mortality, and treatment outcomes, particularly among Black populations. Despite advances in medical care, disparities continue to challenge efforts to achieve health equity. Understanding and addressing these complex issues are imperative to ensure that all individuals, regardless of race or ethnicity, have equal access to effective cancer prevention, diagnosis, and treatment. Alabama stands out as the leading state among the top ten in terms of densely populated Black Belt counties in the United States. With 67 counties in total, Alabama is home to 24 designated Black Belt counties. Given this concentration, Alabama becomes a key focus for comprehending cancer disparities. The ongoing research seeks to examine the occurrence of various types of cancer among the predominant racial groups in the United States, focusing particularly on the Black Belt counties of Alabama. Data on cancer occurrences, obtained from the database of National Cancer Institute (NIH) and the Centers for Disease Control and Prevention (CDC), offer insights into cancer incidences among various demographic groups, age categories, and specific types of cancer spanning the last five years (2016-2020). Analysis of the data, focusing on patients aged 65 years and older, was performed using GraphPad Prism 5 software. Graphs were created to visually represent and interpret the data regarding incidences per 100,000 populations. We observe significantly elevated incidences of major cancer types such as prostate, colon, lung, stomach, pancreas, and liver among Black males, and similarly heightened rates of uterus, cervix, stomach, pancreas, and kidney cancers among Black females, when compared to white populations. Notably, within Alabama's Black Belt regions, only a small number of counties have reported incidences of cancer regardless of gender and cancer types, except for prostate cancer in males and breast cancer in females. Moreover, in certain Black Belt counties, rates of colon and lung cancer (in both males and females), as well as prostate cancer in males and breast cancer in females, are exceptionally elevated compared to both the statewide average in Alabama and even the national average in the United States. Generally, females tend to have lower rates of cancer across various types compared to males. In conclusion, factors contributing to these disparities include genetic predispositions, socioeconomic status, healthcare accessibility, systemic biases, and cultural influences. Further investigations, including molecular screening studies, are imperative to corroborate these health disparities and foster community-wide cancer awareness and public health initiatives.
