In developed regions, the 5-year survival rate exceeds 80%, largely due to early detection, diagnosis, and access to effective treatment.[79] Bioinformatics analysis of CCT subunit expression in breast cancer reveals that CCT2, CCT3, CCT5, CCT6A, CCT7, and CCT8 are significantly upregulated, with their expression levels positively correlated with tumor stage. This evidence concerns the gene FLVCR2 and breast cancer.
