Baseline PSA Screening and Long-Term Prostate Cancer Risk

​Baseline levels of prostate-specific antigen (PSA) at age 55 to 60 are correlated with men's long-term risk of developing clinically significant prostate cancer, according to a secondary analysis of long-term follow-up results from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.Once broadly accepted as a tool for the early detection of prostate cancer, PSA screening has become controversial in recent years due to issues of overdiagnosis and overtreatment of slow-growi...

Genital Powder and Ovarian Cancer Risk: No Significant Link

​In recent years, a number of lawsuits have highlighted concerns regarding a possible link between ovarian cancer risk and the use of talc-containing cosmetic powders in the genital area. However, a large pooled analysis now published in JAMA reports no statistically significant association between genital powder use and ovarian cancer.The potential connection between genital powder use and ovarian cancer risk was first investigated because of the relationship between talcum powder and asbestos,...

MRI Reduces Interval Breast Cancers in Dense Breasts

A randomized clinical trial reports that for women with extremely dense breasts, supplemental screening with magnetic resonance imaging (MRI) can reduce the incidence of interval breast cancers­­, those detected within 12 months of a mammography in which findings are considered normal.Extremely dense breast tissue increases the risk of breast cancer, but it also increases the chances that cancer will be missed on a mammogram. While federal law requires the reporting of breast density in mam...

Does Marijuana Use Increase Cancer Risk?

Nearly half of adults have used marijuana at some point in their lives, and rates are increasing; among young adults, marijuana usage doubled from 10.5% in 2002 to 21.2% in 2014. Given this widespread usage, the question of marijuana-associated cancer risk is an important one, and it is the subject of a systematic review and meta-analysis now published in JAMA Network Open.Marijuana smoke and tobacco smoke share a number of carcinogens. In addition, tetrahydrocannabinol, marijuana's primary psyc...

The Deadly Consequences of Fine Particle Air Pollution

A new study finds an association between fine particulate matter (PM2.5) air pollution and deaths from nine different causes, including cardiovascular disease, cerebrovascular disease, hypertension, dementia, and lung cancer, among others. Furthermore, 99% of PM2.5-associated deaths were linked to levels of PM2.5 exposure currently deemed acceptable by US Environmental Protection Agency (EPA) recommendations.Atmospheric particulate matter with a diameter of less than 2.5 micrometers, PM2.5, is p...
