"Reviving Exhausted Immune Cells: A Breakthrough in Preventing Breast Cancer"

A study suggests that "exhausted" immune cells in the breast tissue of women with faulty BRCA1 or BRCA2 genes could be the key to preventing breast cancer before it develops. Existing drugs, typically used for late-stage disease, may be repurposed for preventative treatment. The study offers hope for using immunotherapy drugs to prevent breast cancer in high-risk individuals, potentially eliminating the need for surgery. This discovery could be a significant step forward in the care and treatment of people at increased risk of developing breast cancer.
