  schema:description "Two labels for a gallbladder cancer that has grown through the muscle layer but is still inside the gallbladder. T2a sits on the free side facing the abdominal cavity; T2b sits on the side pressed against the liver, spreads to nodes and vessels more often and roughly doubles the risk of dying, so the surgeon removes more liver for it."@en ;
