Summary
Cancer Registry Data Online (CaRDO) is a free R package that helps cancer registries visualize and share data. It overcomes resource and technical barriers, improving public health communication for cancer control.
Area of Science:
- Public Health
- Biostatistics
- Cancer Epidemiology
Background:
- Population-based cancer registries are vital for cancer surveillance and control.
- Limited resources and technical capacity hinder effective data communication from many registries.
- There is a need for accessible tools to visualize and disseminate cancer statistics.
Purpose of the Study:
- To introduce CaRDO (Cancer Registry Data Online), a novel R package.
- To provide an accessible, user-friendly tool for creating interactive cancer data dashboards.
- To support cancer registries in data visualization and dissemination.
Main Methods:
- CaRDO is an R package built on the R Shiny framework.
- It enables offline dashboard generation with minimal programming experience.
- Incorporates epidemiological methods (age-standardized rates, lifetime risk, trend analysis) with privacy safeguards.
Main Results:
- CaRDO facilitates the display of cancer incidence and mortality data by various demographics and measures.
- Visualizations include temporal trends, and data processing occurs locally.
- Dashboards are customizable, with downloadable plots for reports and presentations.
Conclusions:
- CaRDO offers a practical solution to enhance the visibility and utility of cancer registry data.
- It removes financial and technical barriers for under-resourced registries.
- The tool supports data-driven public health communication in cancer control.

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...
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.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
01:12Statistical Software for Data Analysis and Clinical Trials
Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...
02:12What is Cancer?
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
