About

Many postmenopausal women have vasomotor symptoms during adjuvant hormonal treatment for breast cancer. PCC-100 is a pollen extract used for alleviation of postmenopausal symptoms. In a randomised, double blinded study pollen extract PCC-100 will be used to treat vasomotor complaints in postmenopausal women under adjuvant hormonal treatment and also in menopausal women without a history of breast cancer.
