Brief Summary: This study explored the combined effect of genetic predisposition and radiation exposure on the risk of developing subsequent cancers in survivors of childhood cancer. It included genotype data from 11,220 5-year survivors and focused on six subsequent cancer types: basal cell carcinoma (BCC), breast cancer, thyroid cancer, squamous cell carcinoma (SCC), melanoma, and colorectal cancer. Polygenic risk scores (PRS) were derived from genome-wide association studie...
