For these nine signaling pathways, including cell cycle, Hippo, MYC, Notch, NRF2, TP53, PI3K, RTK‐RAS, and WNT, the genomic alterations promoting oncogenic activities while inactivating tumor suppressor functions were much more frequently observed in TS‐CB and TS‐CC than in TS‐CA. This evidence concerns the gene MYC and neoplasm.
