Background

Cancers can be diagnosed at different stages in their development. Stage of cancer diagnosis may be expressed as numbers (for example, I, II, III, or IV) or by terms such as “localized,” “regional,” and “distant.” The lower the number or the more localized the cancer, the better a person’s chances of benefiting from treatment.

Tracking the rates of late-stage (distant) cancers is a good way to monitor the impact of cancer screening. When more cancers are detected in early stages, fewer should be detected in late stages.

Both rates of late stage disease and stage proportions are provided below since each has a somewhat different interpretation. For example, rates could be declining among all stages of disease, but the proportion of late stage disease among diagnosed cases could be relatively constant.

Measure

Late-stage diagnosis rate: The number of new cancer cases diagnosed at a distant stage per 100,000 people per year for cancers of the prostate, lung and bronchus, colon, rectum, and cervix uteri. Late stage is defined as regional and distant stage diagnoses, per 100,000 women per year for cancer of the female breast. Late stage is defined as the stages which screening tends to reduce and differs by cancer site (i.e. when screening is initiated the proportion diagnosed with late state disease goes down).

Stage Distribution:  The proportion of new cancer cases among all cases diagnosed in a specific year.  The full distribution of all stages (local, regional, distant and unstaged/unknown) is shown.

Healthy People 2030 Target

  • There are no Healthy People Target for breast, colon, rectum, cervix uteri, lung and bronchus or prostate cancer by stage at diagnosis.

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