Breast Cancer Risk, Screening, and Prevalence Among Sexual Minority Women: An Analysis of the National Health Interview Survey.

Abstract

Purpose: Sexual minority women (SMW) may have a different distribution of breast cancer risk factors than their heterosexual peers. Epidemiologic studies of breast cancer in SMW have been limited, and many use only proxy variables to identify SMW in data sets, introducing selection bias. We utilized National Health Interview Survey (NHIS) data to compare breast cancer risk factors, screening, and prevalence between SMW and non-SMW. Methods: We identified female respondents to the NHIS from 2013 to 2017, selected women ≥40 years old and stratified by sexual orientation. We compared demographics and health maintenance variables and prevalence of breast cancer diagnosis between groups and performed a multivariable analysis of breast cancer risk. Results: Of 58,378 women ≥40 years old, 1162 (2.0%) were identified as SMW. SMW were younger and more likely to use tobacco and alcohol, be younger at menarche, and be nulliparous. SMW also reported less preventive care, and despite reporting equivalent rates of mammography, were more likely to obtain mammograms due to an identifiable problem and not simply for screening purposes. Prevalence of breast cancer was similar between SMW and non-SMW (4.7% vs. 5.0%, p = 0.67), and SMW status was ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
