Refined Deep Learning Model Accurately Measures Breast Density

Breast density is a significant factor in determining breast cancer risk. Dense breasts have a higher risk of developing breast cancer compared to breasts with less dense tissue. Thus, measuring breast density correctly is critical in identifying individuals who need additional breast cancer screening.

In recent years, deep learning techniques have been utilized to improve breast density measurements. A new study published in Radiology takes this a step further by introducing a refined deep learning model that accurately measures breast density from full-field digital mammography.

What is breast density?

Breast density refers to the proportion of different types of tissue in the breast. Dense breast tissue has more glandular and fibrous tissue than fatty tissue. On mammograms, dense tissue appears white, making it difficult to detect small tumors that may also look white. Alternatively, fatty tissue appears dark, making it easier to identify irregularities.

The importance of measuring breast density

Accurate breast density measurement is crucial in identifying individuals who are at a high risk of developing breast cancer. Dense breast tissue can also mask potential tumors, making early detection and diagnosis difficult. Females with dense breasts are also more likely to receive false-negative results from mammograms. Therefore, accurate measurement of breast density is vital for early detection and successful treatment of breast cancer.

What is a refined deep learning model?

Deep learning models are artificial neural networks that simulate the human brain. They can learn from large volumes of data and improve predictions over time. In this study, researchers developed a refined deep learning model that improved breast density measurements from screening mammograms.

The model was trained on almost 25,000 images from more than 15,000 women. It used a combination of convolutional neural networks and transfer learning to improve accuracy. Transfer learning is where an existing model, in this case, a model already trained at deep learning, is re-purposed and further trained to deliver better results.

What were the study findings?

The refined deep learning model demonstrated excellent accuracy in measuring breast density. The model provided reliable breast density measurement with an average difference of 0.37% compared to human radiologists. The findings of this study demonstrate the potential of refined deep learning models, providing hope for improving breast cancer screening and diagnosis for millions of individuals worldwide.

Conclusion

Accurate measurement of breast density is essential for identifying individuals who are at high risk of developing breast cancer, and deep learning models can improve breast density measurements significantly. The refined deep learning model developed in this study, with additional training on mammogram images from diverse populations, will help further refine the accuracy of breast density measurements. Ultimately, this will assist in identifying individuals vulnerable to breast cancer and allow for early, successful treatment of the disease.
