Indicator Report Data View Options
Why Is This Important?
In New Jersey, 7,346 women were diagnosed with breast cancer in 2020. Breast cancer is the most common cancer among women in the United States, other than skin cancer. It is the second leading cause of cancer death in American women, after lung cancer.
Definition
Incidence rate of invasive breast cancer in females for a defined population in a specified time interval. Rates are age-adjusted to the 2000 U.S. Standard Population. Rates are per 100,000 population.
Data Notes
- Data have been age-adjusted to the U.S. 2000 standard population.
- Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population (19 age groups: <1, 1-4, 5-9, ..., 80-84, 85+). Rates are for invasive cancer only (except for bladder cancer which is invasive and in situ) or unless otherwise specified. 2020 data are considered preliminary and should not be used in trend analyses; an approximate 10% decrease in the number of cancer cases diagnosed in 2020 compared to 2019, is partly due to the COVID-19 pandemic. Patients experienced difficulties scheduling medical appointments and cancer screening tests in 2020.
