when fresh breast tumor tissue fragments were incubated with radioactive e2 ( 0.4 nm ) and e2s ( 3 nm ) separately , e2 was not sulfurylated appreciably while e2s was extensively hydrolyzed to free estrogens indicating that the combined effect of es and esft in breast tumor is favored towards the hydrolysis of estrogen sulfate .
