Should You Take HRT After Breast Cancer? Dr Liz O'Riordan weighs In

Do you want to know why saying “HRT is safe after breast cancer because we used to treat breast cancer with oestrogen” is wrong?

Watch this video. I’ve read the books and studies the trials that Dr Newson and Dr Bluming refer to when they make comments like this.

Here’s what you need to know:
High dose oestrogen was used to treat breast cancer
In the 1940s-70s
For women with advanced / fungating / metastatic breast cancer who are beyond treatment by surgery or radiation
Before we knew about Er Pr HER2 receptors, surgical margins, tamoxifen, immunotherapy, targeted radiotherapy…
It only slowed growth in less than half of the women
It only worked in those who WERE OVER 60
In younger women, it SPED UP GROWTH
It had hideous side effects - anorexia, vomiting, vaginal bleeding, urinary incontinence and heart failure

When Tamoxifen was first used for advanced breast cancer, (again before we knew about ER receptors), it had the same effect - slowed growth in 30% women with much better side effects. So we stopped using high does oestrogen

new evidence shows that high dose oestrogen could be used today to treat metastatic breast cancer - it ONLY works after a long period of oestrogen deprivation of several years - so after Tam/ AI etc. This massive dose appears to be toxic to some breast cancers.

I don’t think anyone could read this and then claim that HRT is safe after breast cancer - especially when oestrogen increased the growth of metastases in younger women
