Liver cancer is abnormal cell growth in the liver cells. The liver plays an important role in removing harmful substances from our blood. This includes environmental contaminants people come into contact with during their lifetimes. Even though the liver usually does a good job at removing those harmful substances, certain chemicals have been shown to damage the liver. For example, studies have shown that some people who drink water containing high levels of arsenic over many years could experience health effects including liver cancer.

Back to topAnnual Liver Cancer Incidence Data
Annual cancer incidence measures can be used to identify trends and patterns of cancer incidence over time. Annual measures are only available at the state level. County level cancer incidence measures are available as five-year aggregate data.
Measure Description:
- The Cancer Count is the number of newly diagnosed malignant cancers.
- The Crude Rate (Per 100K) is the rate of newly diagnosed malignant cancers per 100,000 population
- The Age Adjusted Rate (Per 100K) is the age adjusted rate of newly diagnosed malignant cancers per 100,000 population. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
5-Year Liver Cancer Incidence Data
Five Year incidence measures can be used to identify trends and patterns of cancer incidence over time and in different geographic areas. Five-year aggregate measures are available at the state and county level. Five-year aggregate data is used to reduce the presence of suppressed values due to small numbers; allowing display of data, and stabilization of rates to better evaluate trends. Even with this aggregation some values still need to be suppressed.
Measure Description:
- The Average Annual Count is the average number of newly diagnosed malignant cancers per year in the five-year period.
- The Crude Rate (Per 100K) is the rate of newly diagnosed malignant cancers per 100,000 Population during the five-year period.
- The Age Adjusted Rate (Per 100K) is the age adjusted rate of newly diagnosed malignant cancers per 100,000 Population during the five-year period. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
