When comparing the urinary levels of BLACAT1 in schistosomal (37 cases) and non-schistosomal BC groups (33 cases); there was no significant difference between the two groups, where the superficial stages (T0 + T1) in schistosomal BCs showed expression levels of BLACAT1 (0.28 ± 0.08) compared to (0.38 ± 0.1) in non-schistosomal BCs. Here, BLACAT1 is linked to breast cancer.
