What Are the Most Recently Available Cancer Data?
Hospitals, physicians, pathology laboratories, and radiation therapy facilities are required to send information on newly diagnosed cases of cancer in Massachusetts to the Massachusetts Cancer Registry (MCR). To assure accuracy, multiple quality control activities are performed. Data are generally released 2-3 years after they are received. It may be even longer before Massachusetts data on cancer cases by city and town are released. Other cancer data, such as cancer deaths, may be available sooner.
What Should I know When Interpreting Cancer Data?
When examining the data, keep in mind:
- Cancer is a general name for a variety of diseases with different causes and associated factors.
- It can take many years from the time people are exposed to cancer-causing agents until the time they develop cancer.
- Cancer rates may be different between geographic areas because of variations in racial/ethnic populations, screening rates for cancer, health behaviors (such as use of tobacco, eating habits, or levels of physical activity), or simply due to chance.
- Rates based on a small number of cases or deaths should be interpreted cautiously.
- Just because something is statistically significant does not necessarily mean there is a problem.
