Rather, secreted GAG or Sia decorated mucin-rich tumor cell products surrounding tumor nests or modifying basement membranes as glycan-rich ECM barriers may be vulnerable to EM waves or magnetic pulsing to disrupt or “loosen” a kinetic barrier to immunologic traffic (75, 76), including both tumor antigen sensitized or naïve T cells, gaining access to tumor-cell products, which also include apoptotic or tumor dead-cell fragments. Here, MUC5AC is linked to neoplasm.
