Women are generally told that if they have a breast cancer diagnosis, they should steer clear of estrogen. In this episode, I have a conversation with Dr. Swati Kulkarni, the lead investigator of a new study in which women with a newly diagnosed breast ductal carcinoma in situ, DCIS, were given a month’s worth of hormone therapy before standard treatment to see the impact it would have on developing cancer cells. 
  • What DCIS is and how it is typically diagnosed.
  • If DCIS is considered to be a pre-cancer or a cancer
  • If DCIS is untreated, how often it will progress to invasive cancer 
  • If treated, how often women with DCIS go on to develop invasive cancer? 
  • Why this particular form of hormone therapy, conjugated estrogens and bazodoxifene (Duovee™) was used in the study
  • The details of the study
  • The results of the study
 The Promise Study: A presurgical randomized clinical trial of CE/BZA vs placebo in postmenopausal women with ductal carcinoma in situ.
