Cancer treatments alter the landscape of genetic mutations in healthy body tissues

https://www.news-medical.net/news/20260911/Cancer-treatments-alter-the-landscape-of-genetic-mutations-in-healthy-body-tissues.aspx Cancer treatments, including chemotherapy and radiotherapy, give a growth advantage to cells with particular genetic changes in healthy tissue, new research finds. Researchers from the Wellcome Sanger Institute, University of Cambridge, University College London and their collaborators used DNA sequencing to map the mutations in normal esophagus tissue from esophageal cancer patients who had received either chemotherapy, chemotherapy and radiotherapy, or no treatment before surgery.
