Lymphoma is cancer of the lymphatic system. The lymphatic system helps transport immune cells throughout the body to fight infections. Measures are available for multiple types of lymphoma; however, the Tracking Network features information on Non-Hodgkin Lymphoma.
Non-Hodgkin Lymphoma
Non-Hodgkin lymphoma (also called non-Hodgkin's lymphoma, NHL, or just lymphoma) is a group of cancers that start in lymphoid tissue (also called lymph or lymphatic tissue) and can then spread to other organs. The causes of Non-Hodgkin lymphomas are mostly unknown. Specific viruses, immune deficiency, and specific autoimmune conditions have been implicated in increased risk. However, some environmental issues, including exposures to pesticides and solvents, are also being investigated. Read more about lymphoma.
Annual Lymphoma 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 Lymphoma 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.
