Incidence

On This Page:

Cancer incidence is typically measured as the number of new cases each year for every 100,000 people (for sex-specific cancers, people of the same sex serve as the denominator) and age-adjusted to a standard population to allow comparisons over time.

In 2024, nearly half of all new cancer cases are expected to be cancers of the prostate, breast, lung, and colon and rectum. According to American Cancer Society projections, about 2,001,140 new cases of cancer are expected to be diagnosed in 2024, including 299,010 cases of prostate cancer, 313,510 cases of breast cancer, 234,580 cases of lung and bronchus cancer, and 152,810 cases of colorectal cancer.

Incidence rate: the observed number of new cancer cases per 100,000 people per year, adjusted for age and cancer case reporting delays and based on data from approximately 10 percent of the U.S. population.

Delay adjustment: a method of estimating delayed reporting of incident cases and then adjusting rates to account for this delay.

Trend lines: calculated from the underlying rates using the Joinpoint Trend Analysis Software.

There are no Healthy People 2030 targets for cancer incidence.

Healthy People 2030 is a set of goals set forth by the Department of Health and Human Services.
