In a study recently published in JAMA Network Open, a team of investigators led by Paulette Chandler, MD, MPH, found that vitamin D supplementation is associated with a decreased risk of developing advanced cancer, particularly among individuals with a normal body mass index (BMI). In this interview with i3 Health, Dr. Chandler, an Assistant Professor of Medicine at Harvard Medical School, discusses the significance of these results and the ongoing research investigating vitamin D supplementatio...

In individuals without cancer, vitamin D supplementation may decrease the risk of developing advanced cancer, especially for those with a normal body mass index (BMI), according to a recent analysis of a phase 3 trial. "Vitamin D may decrease tumor invasiveness and propensity to metastasize, leading to reduced cancer mortality," write the investigators, led by first author Paulette D. Chandler, MD, MPH, Assistant Professor of Medicine at Harvard Medical School. "Vitamin D may have a role in redu...

Patients who undergo baseline lung cancer screening are less likely to adhere to screening recommendations compared with the screening rates of patients who participate in randomized clinical trials, according to a meta-analysis now published in JAMA Network Open. Undergoing regular cancer screening has been shown to reduce the risk of cancer mortality. Data from the 2018 National Health Interview Survey found that approximately 70% of eligible women underwent breast cancer screening within the ...

According to a study recently published in JAMA Network Open, a high proportion of older adults with average cancer risk are overscreened for colorectal, cervical, and breast cancers after surpassing specified upper age limits recommended by the US Preventive Services Task Force (USPSTF). In this interview, Jennifer L. Moss, PhD, first author of the study, discusses the significance of these findings, explains the risks of overscreening, and shares advice for reducing overscreening among older a...

During the COVID-19 pandemic, guidelines from the American Society of Clinical Oncology and other organizations have recommended that cancer screening procedures involving in-person visits, such as mammograms and colonoscopies, be postponed. These delays have contributed to a whopping 46.4% drop in the combined rate of new diagnoses for six cancers. This is the finding of a cross-sectional study, results of which have now been published in a research letter in JAMA Network Open, a...
