The variation of breast parenchymal patterns with age

The British Journal of Radiology
G H Whitehouse, S J Leinster


The Wolfe classification of mammographic parenchymal patterns has been applied to 9036 women attending a Breast Cancer Screening Unit. Overall, two thirds fell into high risk categories (P2 and DY). The incidence of DY decreases with age, while the low risk categories (N1 and P1) increase with age. P2 remains constant over most of the age range. The implications of these findings are discussed and comparison is made with other series.

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.

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.
