Summary
Choropleth maps are vital for visualizing cancer incidence data in community reports. This series addresses common questions on designing these maps for cancer control planning and evaluation.
Area of Science:
- Geographic Information Systems (GIS) in Public Health
- Spatial Analysis of Disease Incidence
Background:
- Choropleth maps are frequently utilized in cancer reporting and public health discussions.
- Cancer registries are increasingly adopting Geographic Information System (GIS) techniques for data visualization.
- The Centers for Disease Control and Prevention (CDC) established a Map Work Group to guide GIS mapping in cancer control.
Purpose of the Study:
- To address frequently asked questions regarding choropleth map design for cancer incidence data.
- To promote the use of choropleth mapping for comprehensive cancer control planning and evaluation.
- To guide the application of GIS mapping techniques by central cancer registries.
Main Methods:
- The study is presented as a 2-part series answering common questions on choropleth map design.
- Focuses on data from central cancer registries supported by the National Program of Cancer Registries.
- Recommendations for future initiatives are discussed.
Main Results:
- Provides guidance on designing effective choropleth maps for cancer incidence data.
- Highlights the importance of choropleth maps in cancer control planning and evaluation.
- Identifies areas for improvement in current mapping practices.
Conclusions:
- Future initiatives should explore advanced mapping, spatial analysis, and spatial statistics.
- Usability testing with state/local programs and cancer prevention partners is recommended.
- Effective map design is crucial for communicating cancer data and supporting public health efforts.

01:04Pie Chart
A pie chart (or a pie graph) is a circular graphical chart or a pictorial representation of categorical data. It is divided into slices of pie each indicating numerical proportions. It is also used to show the relative sizes of data in a single chart.
In a pie chart, the central angle, the arc length of each slice, and the area are directly proportional to the quantity or percentage it represents. Some real-world examples that can be depicted using pie charts include marks obtained by students...

01:21Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
00:52Pareto Chart
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...

02:43Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
