Thus, tumor‐associated carbohydrate antigens, (TACAs), which are aberrantly expressed at the surface of tumor cells compared with normal cells, either as glycolipids (GM2, GD2, GD3, Globo H) or as mucin glycoproteins (Tn, TF, STn, MUC1),86 have become important targets for antibody recognition and immune attack against cancers (Figure 3, Table 2). Here, MUC1 is linked to cancer.
