    Endocrine therapy agents (the selective estrogen receptor (ER) modulators such as tamoxifen or the selective ER down-regulators such as ICI 182,780) are key treatment regimens for hormone receptor-positive breast cancers. ...
  • Kochan, David Z.; Kovalchuk, Olga (Impact JournalsArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2015)
    Breast cancer is already the most common malignancy affecting women worldwide, and evidence is mounting that breast cancer induced by circadian disruption (CD) is a warranted concern. Numerous studies have investigated ...
