Examining rates based on age, race, and tumor characteristics could guide the development of prevention strategies. Over the past twenty years, there has been a consistent rise in breast cancer diagnoses among women younger than 50, with the rate of increase becoming more pronounced in recent years
Breast cancer diagnoses in women under 50 have increased significantly in the past two decades, primarily driven by estrogen-receptor positive tumors. This research highlights the importance of early detection and the need for prevention strategies. Prevention efforts in young women need to adopt a targeted approach to address racial disparities in incidence rates observed at different age phases.
Can this be explained by screening? i.e. they actively screen for breast cancer so they're going to find it even in cases where it wouldn't have ever affected the patient.
I haven't read the link (not in the mood to parse it) but that's my gut reaction to the title. I highly recommend this video by Medlife Crisis https://youtube.com/watch?v=yNzQ_sLGIuA (also on Nebula) that explains the flaws of screening, it's approachable and it's a fun watch if you're into YouTube edutainment stuff.
I do recall reading somewhere that women throughout the industrialized world have seen their breast size increase substantially since the mid-20th Century. Sadly, risks of cancer increase along with this
