Study start date: November 1, 2008

Actual date on which the first participant was enrolled.

This study focuses on postmenopausal women and aims to compare the effects of two different hormone therapies on the breast. The first therapy combines Oestradiol (E2) with Drospirenone (DRSP), while the second combines Oestradiol (E2) with Noresthisterone Acetate (NETA). The goal is to understand which therapy has a more favorable impact on the breast over a six-month period. This research is important as it could help improve the care and treatment options for postmenopausal women. During the study, participants are randomly assigned to one of the two hormone therapies. The first group receives an oral dose of 1 mg Oestradiol (E2) combined with 2 mg of Drospirenone (DRSP), while the second group receives an oral dose of 1 mg of Oestradiol (E2) combined with 0.5 mg Noresthisterone Acetate (NETA). The primary outcome measured is the mammographic breast density, which is evaluated using digitized data-based quantification of breast density. This helps to assess the changes in the breast tissue after the hormone therapies.
