Trends in Early Onset Cancers
A research team led by Dr. Meredith Shiels analyzed cancer incidence and mortality rates for 33 cancers in different age groups in the United States. The study analyzed how cancer rates in people under 50 have changed over time compared to older age groups (70 to 79 years). The results could generate insights into risk factors that are particularly important in early age groups.

Study of Oral Microbiome Describes the Mouth of America
A research team led by Dr. Christian Abnet characterized the composition, diversity, and correlates of the oral microbiome of US adults in a new cross-sectional study. They described the associations between age, sex, tobacco use, alcohol, BMI and other individual characteristics and different aspects of the oral microbiome. This is the first population representative description of a human microbiome, which that includes describing the the prevalence of different bacterial genera in the US population.

Hormuzd Katki Departs After 26 Years of Service
Hormuzd Katki, senior investigator in the Biostatistics Branch, accepted early retirement in April 2025. Dr. Katki is internationally recognized for his work to develop and apply quantitative methods to identify and answer the most pressing questions in cancer epidemiology. He translated these findings into tools for the prevention and early detection of cancer in individuals and populations, particularly for cancers of the cervix and lung, and developed metrics for evaluating risk models and biomarkers.

Light Intensity Physical Activity Linked to Lower Cancer Risk
A new NIH study of 85,000 adults in the United Kingdom found that individuals who engaged in light- and moderate-to-vigorous-intensity daily physical activity had a lower risk of cancer than individuals who were more sedentary. Participants in the study wore accelerometers to track their total daily activity, its intensity, and daily step count. The researchers determined that a higher step count, at any pace, can help lower cancer risk.

Self Collection for HPV Testing to Prevent Cervical Cancer: New Guidelines Published
New guidelines for clinicians advise on cervical cancer screening using self-collected vaginal samples. Self-collection expands screening options and has potential to increase access for individuals who have never been screened or are not receiving adequate screening.

Prototype AI Program Detects Biomarkers that Could Predict Cervical Cancer Risk
The NIH Intramural Research program highlights Dr. Nicolas Wentzensen’s prototype artificial intelligence program that reviews cervical cell samples and detects proteins that could predict cervical cancer risk.

Kiyohiko Mabuchi Retires from the NCI After 20 Years of Service
Kiyohiko Mabuchi, senior scientist in the Radiation Epidemiology Branch, retired from the National Cancer Institute in early 2025 after more than 20 years of service. Dr. Mabuchi investigated cancer and chronic disease risks associated with exposure to ionizing radiation and how radiation-related risks are modified by modes of exposure and other factors.

Pacific Islander Adults Experience Significantly Higher Overall and Leading-Cause Death Rates than Asian American Adults in the U.S.
Health data of Asian Americans and Pacific Islander individuals have often been aggregated, but Jacqueline B. Vo, Jaimie Z. Shing, and colleagues observed significantly higher death rates among Pacific Islander individuals compared to Asian Americans between 2018 and 2020.
