“…Although several epidemiological studies revealed increased relative risk of subsequent BC in women who have had previously GCBD [5,14, [32][33][34], other cohort studies have failed to find any increased relative risk [35][36][37][38][39][40][41][42][43][44][45][46], concluding that GCBD cannot be considered a precancerous lesion per se (Table 3 and 4). Different risk profiles were also found in gross cyst subtypes [22,62], showing that Type I apocrine gross cysts are frequently associated with an increased risk of BC [6,24,34,59,63], even though several controversial/conflictual results are reported [29,45,58,60,64,65].…”
