Therapies developed to treat breast cancer have significantly improved patient survival rates. But their consequences on the body would be more significant than we thought. Common breast cancer treatments, including chemotherapy, radiation therapy and surgery, may accelerate the biological aging process in women, according to a new study led by researchers at the University of California, Los Angeles (UCLA). the survivors.
“Similar changes in those who only underwent radiotherapy or surgery”
« While we expected to see an increase in gene expression linked to biological aging in women who received chemotherapy, we were surprised to see similar changes in those who only underwent radiation or surgery. “, summarizes the lead author of the study, Judith Carroll, professor and researcher at the UCLA Health Jonsson Comprehensive Cancer Center. To examine how genetic expression affects aging in women diagnosed with breast cancer, the team conducted a two-year longitudinal study. Scientists followed women before and after their treatment, to observe the evolution of biological markers of aging.
