Native Hawaiian women now hold the highest breast cancer incidence rate of any group of women in the United States, a fact hidden for years by government paperwork that lumped them in with Asian Americans.
Quick Take
- New American Cancer Society data show Native Hawaiian women have 27% higher breast cancer incidence than White women once separated from broader Asian American statistics.
- Combining Asian American and Native Hawaiian and Pacific Islander populations into one category has long masked which communities face the highest cancer risk.
- Native Hawaiian and other Pacific Islander people already faced 75% higher liver cancer death rates and two to three times higher death rates from cervical, stomach, and endometrial cancers compared to White people.
- Researchers say breaking down the numbers by specific ethnic group is now essential for building effective prevention and screening programs.
A Hidden Crisis Finally Gets Counted
The American Cancer Society released findings on August 27, 2026, showing Native Hawaiian women carry the highest breast cancer incidence rate in the country. Researchers reached that conclusion only after separating Native Hawaiian data from the broader Asian American and Pacific Islander category government agencies typically use. For years, that combined label buried the real story. Native Hawaiian women were simply invisible inside a much larger statistical group.
Once researchers pulled Native Hawaiian data out of the mix, the picture changed fast. Their breast cancer rate came in 27% higher than White women’s rate, making them the single highest-risk group in the nation for this disease. That kind of gap does not show up when statisticians average dozens of different ethnic backgrounds together under one broad label.
Why Lumping Groups Together Hides Real Danger
Government health agencies have long grouped Asian Americans and Native Hawaiian and Pacific Islanders into a single category for convenience. The problem is size. Asian Americans vastly outnumber Native Hawaiian and Pacific Islander populations in the United States, so their statistics tend to dominate the combined numbers and drown out smaller groups facing far worse outcomes.
This is not a new pattern for Native Hawaiian and Pacific Islander communities. A first-of-its-kind report from the American Cancer Society already found these groups are 75% more likely to die from liver cancer than White people. They also face two to three times higher death rates from cervical, stomach, and endometrial cancers, all conditions considered largely preventable with proper screening and early treatment.
What Separating the Numbers Actually Reveals
Federal cancer researchers have documented this masking effect across multiple types of cancer, not just breast cancer. One federal analysis found overall cancer death rates were 39% higher among Native Hawaiian and Pacific Islander men and 73% higher among Native Hawaiian and Pacific Islander women compared to Asian American peers, differences that disappeared entirely when the two groups were reported together.
Human papillomavirus-related cancers show a similar pattern once researchers break the data down by specific ethnicity rather than broad category. Cervical cancer rates in particular varied sharply among different subgroups, differences no one could see under the old combined reporting method. The consistency of this pattern across cancer types tells a clear story: broad racial categories built for convenience are failing the very communities they claim to represent.
The Push for Better Data Going Forward
American Cancer Society researchers argue disaggregated data, meaning statistics broken apart by specific ethnic group instead of lumped together, is now essential for effective cancer prevention. Without it, health officials cannot target screening programs, education campaigns, or treatment resources toward the communities that need them most. Native Hawaiian women’s breast cancer numbers prove the point directly. That risk sat hidden inside average statistics for years.
Cancer researchers have called for this kind of breakdown since at least 2023, when federal analysts first flagged how much aggregated reporting was concealing. This latest report gives that argument fresh weight with hard numbers attached. Public health agencies, insurers, and hospital systems now have a clear reason to rethink how they track and report risk across every racial and ethnic category, not just this one.
