20-Year Risks of Breast Cancer Recurrence after Stopping Endocrine Therapy at 5 Years

I really did not want to publish this latest study because Breast Cancer Survivors do not need any more bad news, but I had to do so. If any of you are debating whether to say on Tamoxifen or Aromatase Inhibitors for longer than 5 years, this study of over 62,000 women is important for you to read BEFORE you make your decision with your doctor.

My Oncologist, Dr. Daniel Hayes, M.D. from the University of Michigan was the Senior Author of this study along with his team of International experts. It was just published in the New England Journal of Medicine on November 9, 2017.  I know firsthand how thorough Dr. Hayes is in everything he does, so I had to post this.  Since the time I started Aromatase Inhibitors over 5 years ago, Dr. Hayes told me to plan on 15 years or more of AIs as long as my bones hold out.  Now I know why since he was privy to a lot of information.

This news article in Medscape does a good job of consolidating the information:

  1. These articles can only be accessed if you are a subscriber to these websites. Do you have a link that will allow access without a subscription as the subject is something I am very interested in as a survivor on Tamoxifen with triple positive breast cancer in 2016.

  2. Thank you for sharing. I plan to print the article and take it to my doctor to discuss. (I was already bummed out about the news of Olivia Newton John’s recurrence after 25 years.)
