Key takeaways:
-
Cancer trends are shifting by age, creating new planning considerations for employers and health plans.
-
Colorectal cancer is moving younger, with commercial claims showing growth among adults ages 45 to 54.
-
Breast cancer prevalence is rising across midlife, while the patient age mix remains relatively stable.
-
Cervical cancer trends show that prevention can reduce disease burden when outreach reaches the right cohorts.
Cancer is affecting working-age populations in different ways. For employers and health plans, that means cancer strategy can no longer rely on broad outreach alone. Screening, prevention and benefits planning need to account for how risk is changing across specific age bands.
Why this matters to employers and health plans
Three cancers tell three different stories:
-
Colorectal cancer is rising in younger adults
-
Breast cancer prevalence is increasing across midlife
-
Cervical cancer is showing what successful prevention can look like in the data
The American Cancer Society reports that colorectal cancer incidence is increasing by about 3% per year among adults ages 20 to 49, while rates continue to decline among adults 65 and older. That trend matters for commercial payers because more diagnoses are appearing in the active working-age population.
Where is colorectal cancer increasing by age?
In looking at MarketScan commercial claims data, colon cancer prevalence climbed through midlife as expected, but the 2024 curve sat above 2017 levels after age 35. The patient mix also shifted: adults ages 45 to 54 gained three points of share, while ages 55 to 65 declined.
For employers and health plans, this is more than an epidemiology headline. Colorectal cancer growth among younger and midlife adults can affect active employee populations, near-term medical costs and the design of screening outreach.
What do breast cancer age trends show?
Breast cancer shows a different pattern. MarketScan data indicates higher prevalence in 2024 across midlife, with the increase beginning in the late 30s. However, unlike colon cancer, the age mix changed very little: adults ages 55 to 65 remained just over half of patients.
That distinction matters. Breast cancer trends point less to a dramatic age shift and more to a broader increase in prevalence across working-age and older commercial populations. Plans may need outreach strategies that support screening adherence across multiple age bands rather than focusing only on the youngest eligible members.
What does cervical cancer reveal about prevention?
Cervical cancer tells a more encouraging story. In the MarketScan view, prevalence peaks in the twenties and then falls with age, while the patient mix is moving older. Patients under 35 dropped from 44% of cases to 22%, a pattern consistent with the impact of HPV-vaccinated cohorts.
For plan sponsors, the message is practical: prevention can be measured when programs reach the population early enough. Cervical cancer trends show the value of aligning vaccination, preventive care and age-specific outreach before risk becomes costlier downstream.
How can health plans and employers respond?
Cancer planning should not treat the covered population as one broad group. The data support a more targeted question: which age bands need which interventions now?
-
Target colorectal cancer outreach to younger eligible adults, especially members approaching or entering midlife.
-
Support breast cancer screening engagement across midlife because prevalence is rising more broadly.
-
Use cervical cancer trends as evidence that prevention can reduce disease burden when age-specific programs reach the right cohorts.
The planning question is no longer whether to target cancer prevention and screening. It is which ages to target, what message to use and how to align outreach with the populations where risk is emerging or prevention is working. Truven can help employers and health plans identify those shifts and make cancer strategy more precise.
