The means of the two treatments were compared using the SAS program version 6.3.


RESULTS
The following variables showed significant difference: mother and father family background with cancer p=0.032; previous breast pathology p=0.0032; hormone consumption p=0.0289; lactation p=0.038 and time of lactation p=0.036.
