Modification of oral contraceptive relationships on breast cancer risk by selected factors among younger women

Contraception
L A BrintonR J Coates

Abstract

In a case-control study of 1647 breast cancer cases and 1501 population controls under 45 years of age, potential modifying effects of other risk factors on the relationship of oral contraceptives to breast cancer were examined. Among the total series of study subjects, the relationship of extended pill usage was greater in non-white than white women. Oral contraceptive associations, however, did not appear to be substantially modified by other risk factors, including parity, body size, or family history of breast cancer (apart from a somewhat enhanced relationship among subjects who reported a sister with breast cancer. Further, oral contraceptive relationships did not vary by a history of benign breast disease, although the majority of subjects began pill usage prior to the development of benign breast disease. Among the women under the age of 35, in whom oral contraceptive relationships were heightened (over a twofold excess risk for use of 5 years or longer), pill relationships were less modified by race than in the total series. Although among these younger subjects there was no effect of pill usage in heavy women, and an enhanced relationship among heavier consumers of alcoholic beverages, these interactive effects were n...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.
