This is not a health challenge for a small population. Having dense breast tissue is common. Nearly half of US women over the age of 40 have dense breasts. Additionally, breast density can vary across different demographics. For instance, Asian women generally have higher breast density. This variability drove the creation of different scales for measuring breast density in regions like Japan, where using the standard U.S. scale would categorize most women on the higher end of the density spectrum.

The role of AI in advancing breast cancer detection
AI technology can address the limitations of traditional breast cancer screening methods, particularly in cases involving dense breast tissue.
AI algorithms, trained on large and diverse datasets, can enhance image analysis by identifying subtle patterns and anomalies that are difficult for the human eye to see, particularly in dense breast tissue.

Moreover, AI can assist in personalized risk assessments by analyzing a patient’s medical history, genetic predispositions, and other risk factors. This allows for more tailored screening recommendations and potentially identifies high-risk individuals earlier than traditional guidelines. For example, AI can help triage women with denser breast tissue for supplemental imaging like MRI or ultrasound, improving the likelihood of early detection.

AI's ability to integrate with existing systems and adapt to different imaging technologies further enhances its utility across diverse populations. By reducing false negatives and improving the accuracy of early detection, AI is a powerful tool in the fight against breast cancer.

Global advancements in personalized breast cancer screening
Regulatory bodies and medical societies are promoting personalized screening approaches. For example, the FDA has updated breast density reporting requirements, recognizing dense tissue as a risk factor, and the American College of Radiology (ACR) recommends breast cancer risk assessments for all women by age 25 to identify high-risk individuals early.

Internationally, the European Society of Breast Imaging (EUSOBI) has recommended that countries mandate notifying women of their breast density. This recommendation is driven by research from the DENSE trial in the Netherlands, which demonstrated that supplemental imaging for women with dense breasts significantly improves cancer detection rates.

A unique aspect of the DENSE trial was the use of AI technology to objectively identify the women with the densest breast tissue (category D or higher). These women were then triaged to receive MRI screening, a strategy that effectively managed the limited MRI capacity in the Netherlands by focusing on those at the highest risk.
