Novel Statistical Model in Estimating the Risk of Breast Cancer Recurrence
Although population-based cancer registries data are useful in tracking and reporting the evolving burden of cancer in the population, the information they capture reflects the outcomes of diagnosis and death, regardless of whether the death is due to the disease or to other causes, and not data on ...
Study Finds Deep Learning Can Distinguish Recalled-Benign Mammogram Images From Malignant and Negative Cases
Although digital mammography is effective in detecting early-stage breast cancer and in reducing mortality, high recall rates after a screening mammogram often result in unnecessary medical procedures, including breast biopsies, medical costs, and psychological stress for patients. A...
Study Identifies Specific Genes Associated With Increased Risk for Triple-Negative Breast Cancer
Studies show that triple-negative breast cancer is associated with advanced-stage disease and higher-grade tumors at the time of diagnosis, and carries an increased risk of recurrence and poorer 5-year survival rates relative to other breast cancers. This type of breast cancer accounts for...
