Latest / The Dr Louise Newson Podcast / 55 – HRT, breast cancer and the real risks of not taking hormones
Transcript
- 0:00Doctor Jeffrey Dak is my guest today.
- 0:02He's AUS doctor and he talks a lot about the preventative roles
- 0:07of hormones, talks about how oestrogen can reduce future risk
- 0:12of breast cancer, but also other diseases such as osteoarthritis,
- 0:17osteoporosis and heart disease. We really explore about how we
- 0:22should be thinking differently about hormones and also about
- 0:26how healthcare professionals should be less scared of
- 0:28prescribing hormones to women. Jeff, I'm really excited to have
- 0:34you on my podcast because I've listened to quite a few podcasts
- 0:38that you've been on on other people's your words of wisdom,
- 0:41your huge intellect is just incredible.
- 0:45And also your book, which I have lugged down to London on the
- 0:49train last night, Bioidentical Hormones, 101, Menopausal
- 0:54Hormonal Replacement, second Edition.
- 0:57I'd just like to add, so just before we get started, just tell
- 1:01me a bit about you because you haven't always been a specialist
- 1:05in hormones. So can you just tell me a bit
- 1:07about your story? Yes, of course.
- 1:10First of all, Louise, thank you so much for inviting me.
- 1:13It's a great honor to be on your podcast.
- 1:15And you know, my background, we, I started out as a diagnostic
- 1:18interventional radiologist. I worked in the hospital for 25
- 1:21years doing that. And you know, I developed eye
- 1:25troubles. So I switched to a a outpatient
- 1:30clinic. I started my own outpatient
- 1:32clinic here locally and doing bioidentical hormones at the
- 1:37beginning and, and then I later as, as I, we were chatting
- 1:41earlier, I mentioned that I became a reluctant
- 1:43thyroidologist and we have a second book on natural thyroid
- 1:48toolkit, which, you know, we can get into later.
- 1:51But yeah, the, you know, I, I was prescribing bioidentical
- 1:56hormones for, for 20 years. Their first edition of the
- 1:59bioidentical hormone book came out in 2011 and we talked about
- 2:04the, you know, the Women's Health Initiative study.
- 2:06And at that time there was a, it was a different environment.
- 2:10There was just a lot of negative newspaper articles on, on
- 2:15bioidentical hormone replacement.
- 2:17So a lot of the chapters on the first book dealt with that.
- 2:21The first edition is free on my website.
- 2:23You can download the free version We now have since 2011,
- 2:27you know, another 14 years of research, a lot of new material,
- 2:31a lot of new information, which is really changes the whole
- 2:34landscape. And plus I put it on monthly
- 2:36newsletter and must have tons and tons of material on
- 2:44bioidentical hormones from the newsletter.
- 2:46So I, I had enough material for a book.
- 2:48So I started putting it together and realized, you know what,
- 2:51there's a lot of, there's a lot of medical research that needs
- 2:55to go in the book, which I haven't looked at yet.
- 2:58So as you know, writing a book like this, you get it sort of
- 3:03takes mind a life of its own. And so, you know, that's what
- 3:09goes into the book. You know, when you have these
- 3:12little, these moments where the little light bulb turns on, you
- 3:16know, the Eureka moment. So we do have a few of those in
- 3:19the book. And I, you know, I think it's a
- 3:22good book. I'm a little biased cause since
- 3:24I wrote it and you know, we, we, one of one of the things that we
- 3:30talk about is the Women's Health initiative, you know, 18 year,
- 3:3520 year follow up data came out and showed this tremendous
- 3:41protective effect of estrogen. You know, the, the estrogen
- 3:45treated group had a 4045% reduction in mortality from
- 3:52breast cancer. And I love the quote from Isaac
- 3:55Mananda, who, who is there in London.
- 3:59He's, I think he's at Saint George.
- 4:01He's a professor at Saint George in London.
- 4:03And he's been on, he, I'm, I'm he, I think he's one of your
- 4:07favorites. Also.
- 4:08He comes out and says, you know what, looking at this new
- 4:12evidence, you have to come to the, you're compelled to come to
- 4:15the conclusion that estrogen, it does not 'cause breast cancer,
- 4:18but it's actually preventive. And so the, you know, he's
- 4:23quoted prominently in the book and the and then, you know, the
- 4:29other thing that I didn't know, which I discovered writing the
- 4:31book, is there is a difference between Premarin, which is the
- 4:35hormone estrogen they used in the Women's Health.
- 4:38They should do. It's the difference between
- 4:39Premarin and estradiol, which is the human, you know, the strong,
- 4:44the human hormone E2, which is the, you know, the, the major
- 4:47strong hormone and the, and the difference is horses, you know,
- 4:53primary comes from dragon horses, horse horses have these,
- 5:02these estrogenic compounds that do not appear in humans.
- 5:07It's very interesting because the biggest reason I think, or
- 5:11the commonest reason that people are not taking hormones for
- 5:15perimenopause and menopause and not prescribed hormones is this
- 5:19unfounded fear of breast cancer. Because of the WHI like you say,
- 5:24the Women's Health Initiative study.
- 5:26Because the way it was misreported to the lay media and
- 5:29the medical literature as well that HRT causes breast cancer.
- 5:35And you know, when you unpick the literature and now we've got
- 5:38the luxury of time where we can look at longer term data.
- 5:42Like you say, this risk of breast cancer hasn't actually
- 5:47ever been shown with estrogens, either estradiol, estradol or,
- 5:52or the conjugated equine estrogens of pregnant horses
- 5:54urine. But actually for you to say
- 5:57there's a 45% reduction in mortality to death from breast
- 6:01cancer. And, and it showed that there
- 6:03was about a 23% reduction in incidents of breast cancer.
- 6:07Like why wasn't that headline news?
- 6:09I find that is so important when breast cancer is so common that
- 6:14that's just been dismissed, hasn't it?
- 6:16Well. You know, the the newspapers got
- 6:18it wrong. And of course there was that in
- 6:202002 when the first arm of the study was published, which uses,
- 6:24which used the, the primer along with the synthetic progestin,
- 6:28the medroxy progesterone MPA for short, that, you know, that was
- 6:32the one that showed increased risk of breast cancer.
- 6:37The, the study was halted before it became statistically
- 6:39significant. And then, you know, if you look
- 6:43at the, the later follow up, 18, your follow up there was a, a,
- 6:49you know, a, an increased number of deaths from breast cancer in
- 6:55the synthetic progestin group. It was roughly, roughly you
- 7:02know, the placebo group had about 40 deaths from breast
- 7:06cancer in the 18 year follow up. The Premarin group had almost
- 7:11half that 22 deaths compared to 40.
- 7:16And then the Premarin, the Premarin plus
- 7:19medroxyprogesterone MPA group had 60 deaths from breast
- 7:23cancer. So if you compare the, the
- 7:26formula that in the first arm that was followed in 2002, which
- 7:30is the, the Premarin plus MPA to the, to the Premarin alone,
- 7:36that's gonna be statistically significant in terms of, you
- 7:39know, 60 deaths versus 20. So the statement that there is
- 7:43no studies showing that MPA is, you know, increases mortality
- 7:47from breast cancer with there's no that within with statistical
- 7:53significance. That's, you know, I think that's
- 7:56a little deceptive just to make that statement because #1 the
- 8:01studies are halted early before they can reach significance.
- 8:04And, and it's, it's, you know, to me, it's obvious that if you,
- 8:09if you power a study and, and follow along enough, you're
- 8:14going to see, you know, that type of significance in the
- 8:17numbers, you know, in terms of synthetic progestins being
- 8:21carcinogenic. You know, we know that, for
- 8:23example, there there's a, you know, you go to the university
- 8:28animal lab down this, you know, in the neighborhood and ask the,
- 8:33the, the, the researchers in their little white coats and how
- 8:37did, how do you give mice breast cancer?
- 8:40And one of the, one of the techniques that's widely
- 8:42available is the, they, they inject the mice with medroxy
- 8:46progesterone. There's so many studies now
- 8:49which show that adding a synthetic progestin to an
- 8:54estrogen will increase the risk of breast cancer.
- 8:57The, you know, the, the, the one that's quoted the most is
- 9:00probably the the French cohort study by Agnes Fournier.
- 9:04And she found that, you know, roughly 48% increase in breast
- 9:09cancer when compared to placebo when the medroxyprogesterone is
- 9:14added to estradiol and when estradiol is combined with
- 9:21progesterone, natural progesterone, there is no
- 9:24increased risk of, of breast cancer.
- 9:27You know, the hazard ratio goes back down to 1.0.
- 9:30And then, you know, you can look at the monkey studies.
- 9:32We have an entire chapter in the book on, on entitled don't
- 9:36monkey with my hormones and which is supposed to be cute.
- 9:40And you know, we have these, these monkey labs, you know, the
- 9:44Mac monkeys are very have menstrual cycles very similar to
- 9:48humans. And they, the, they're
- 9:52Physiology response is very similar in terms of response to
- 9:58hormones and breast cancer Physiology.
- 10:01And they, so, you know, Charles Wood compared the
- 10:07doxyprogesterone to estradiol into Premarin and he did all
- 10:13those monkey studies and he found that Premarin Premarin is
- 10:16much less proliferative done this estradiol.
- 10:19And then when you if you add medroxyprogesterone to
- 10:22estradiol, it becomes even more massively proliferative.
- 10:26And then, you know, there's studies done by the one that I,
- 10:30I quote the most is it was done by Sebastian Giuliani in from
- 10:34Argentina. He's a colleague of Claudia
- 10:36Lanieri who did the MPA mouse studies.
- 10:40And he found that that when you when you use medroxyprogesterone
- 10:49added to estrogen, it up regulates ER alpha.
- 10:54And then he found activation of oncogenes, these that are well,
- 11:00very well known in the oncology literature.
- 11:02Medroxyprogesterone activates breast cancer oncogenes.
- 11:06Which is very, it's very interesting because you know,
- 11:09people just think a hormone is a hormone.
- 11:11And over here, and actually not just in UK and other countries
- 11:16as well, doctors, nurses, pharmacists are quite happy to
- 11:19prescribe these synthetic hormones in good faith.
- 11:23They're using them as contraceptives.
- 11:25But I remember going to a talk a menopause society meeting
- 11:29several years ago when they were talking about the dangers of
- 11:32bioidentical hormones, and I'd not really heard this phrase,
- 11:36bioidentical, I didn't really know what it meant.
- 11:39And they were talking about the compounding of how people have
- 11:42hormones made, and they should all be regulated from
- 11:45pharmaceutical companies. But certainly in some countries,
- 11:49it's not possible to obtain estradiol or testosterone unless
- 11:53it's compounded. And in my mind, bioidentical
- 11:58doesn't really matter where it's made.
- 12:00It just means it's the same chemical structure as the
- 12:04hormone that we make ourselves, as in estradiol or estradiol or
- 12:09testosterone or progesterone. But there's been so much
- 12:13confusion on the words. And even when you talk about
- 12:16MPA, magoxy, progesterone, acetate, it's not progesterone.
- 12:20It shouldn't even have that word in its description.
- 12:24So it causes no end of confusion.
- 12:27But metabolically and biochemically, they work so
- 12:31differently in the body, don't they, These synthetic chemical
- 12:35hormones? They have very opposite actions
- 12:37in terms of breast cancer and also in neuro steroid neuro, you
- 12:43know the progesterone, natural progesterone is very
- 12:46neuroprotective with all of those neuroprotective properties
- 12:49are completely obliterated by by synthetic progestins.
- 12:54You know, we do in here in the US we do have FDA approved
- 12:58versions of of pretty much all of all of the bioidentical
- 13:03hormones that in use in hormones in the human body.
- 13:07There are versions of estrogen, you know, there are estradiol
- 13:11patches that are FDA approved progesterone, micronized
- 13:16progesterone oral was approved in 1998, FDA approved in 1998.
- 13:22It was manufactured by Sullivan at the time and that that study
- 13:26was showed that it prevented endometrial hyperplasia.
- 13:30And so also Testosterone's FDA approved versions of that.
- 13:37So estriol is more, yeah, I think approved in Europe, more
- 13:43of an approval in Europe. So here in the US if we want to
- 13:46use estriol, we have to get use that through a company pharmacy.
- 13:50The you know, there there are FDA approved versions of SSG,
- 13:56the estradiol patch and testosterone at the local
- 13:59pharmacy. The reality is FDA approval
- 14:02doesn't necessarily mean you're dealing with a good drug. 10%,
- 14:07yeah, 10% of FDA approved drugs are later with actually
- 14:10withdrawn from the market because, you know, they're bad
- 14:14drugs. And another 10% are given black,
- 14:18the black box warning, which you know, is means this probably a
- 14:23bad drug. When I think about compounded
- 14:25compounding pharmacies, they, they do vary quite a bit in
- 14:30quality. You know, they're little mom and
- 14:32pop compounding pharmacies, all, you know, on the street corner
- 14:36down down the street. And then there we have these
- 14:39large compounding pharmacies that that specialize in women's
- 14:42hormones. There's about half a dozen
- 14:45around in the US and those are the ones that we use.
- 14:47They have much higher quality, much more quality control.
- 14:50And this is just another thing that we don't have to worry
- 14:52about. You know, I look at compounded
- 14:55hormone formulations as sort of a generic form of the F of FDA
- 15:00approved version. You know, the and so you know,
- 15:07it's an awful I can I look at it as as off label prescribing of a
- 15:11generic version. The, you know, in 2020% of all
- 15:15prescriptions in the United States are prescribed off label.
- 15:18There's no FDA approval for that indication 20.
- 15:21You know, that's a big chunk of medical medical practice right
- 15:24there. So, you know, and the other
- 15:27thing to think about is here in the US, every hospital pharmacy
- 15:34is a compounding pharmacy. So, you know, they try not to
- 15:38use compounded formulas. I mean, if they can take
- 15:40something off the shelf, they'll prefer that.
- 15:42But I'll, you know, in the hospital when they make up an IV
- 15:46bag or, you know, you know, there's a significant chunk,
- 15:51significant percentage of the medications that they make up
- 15:54are compounded in every hospital in the United States.
- 15:56So if you get rid of compounding, it's going to be a
- 15:59problem for, you know, the hospital system.
- 16:04I'm really excited to announce that I've written a new book.
- 16:07It's called Power of Hormones. It looks at how hormones
- 16:11actually work in our body and why so much of what we've been
- 16:14told and taught, especially as women, has actually been wrong.
- 16:19I explore the science, the history, and the uncomfortable
- 16:22truths about how hormones have been misunderstood, undertaught,
- 16:27and often dismissed within medicine.
- 16:30There are some stories that are actually quite shocking,
- 16:33frustrating, and I think essential for us all to know.
- 16:37This book is about understanding your body and hormones in a
- 16:40deeper way, about questioning symptoms that haven't always
- 16:44served women well. If you want to be among the
- 16:46first to read it, you can pre-order Power of Hormones now
- 16:50through the link in the show notes.
- 16:55It's all about words really, and understanding.
- 16:58But one of the things that worries me really is that
- 17:01globally, the majority of menopausal women are not
- 17:04prescribed any type of hormone at all.
- 17:07Yet we know there are risks of not having hormones, don't we?
- 17:12That's the big problem, you know, especially in the in the
- 17:15early menopause, you know, the younger women either have
- 17:17hysterectomy or early menopause. You know, there's this
- 17:21tremendous increased risk of early mortality for those
- 17:25people. And you know, all the studies
- 17:29have been done showing that. And, you know, even the in the
- 17:35elderly, you know, there's a recent study called the 10
- 17:39million women studied by Co Bake looked at Medicare records and
- 17:44showed that in the elderly over the age of 65, there are
- 17:48tremendous advantages of hormone replacement.
- 17:51Even, you know, in that in that age group, 20% reduction in
- 17:55mortality is what his data showed.
- 17:59And then there was there was reduction in five different
- 18:02cancers. Why is it, do you think that
- 18:05like so many doctors are resistant to prescribing?
- 18:08Because in the UKHRT prescribing has plateaued over the last
- 18:12year. It's only about 14% of
- 18:14menopausal women. And you know, everyday I speak
- 18:17to women who are actively refused hormones, yet any other
- 18:23drug, if I was bringing a new drug to market and I said, oh,
- 18:26Jeff, I've got this new drug that will reduce mortality.
- 18:30So reduce death rate. It will reduce risk of cancers,
- 18:34it will reduce risk of heart attacks and strokes.
- 18:38Like you'd be going, well, what is it?
- 18:40This is amazing. This is too good to be true.
- 18:43And also then when I say what, it's just a natural hormone I'm
- 18:46just replicating in the body. It's not even a new formula drug
- 18:51that we don't know what's going to happen in the future.
- 18:54I really find it very confusing to understand why there's so
- 18:57much resistance. Here in the US and also
- 19:01probably, you know, the rest of the world, the, the use of
- 19:04hormone replacement plummeted. We, we had 30 million women
- 19:08using hormone replacement in 2002.
- 19:10Once the, that first armed of the Women's Health Initiative
- 19:13study was published, you know, use of hormone replacement
- 19:17plummeted down to 5% of instead of, you know, and the, and the
- 19:25other thing that happened, which which doctor Marty Makary
- 19:28mentioned when he was on the medical school stopped teaching
- 19:32it. And so we, this is 20 years now
- 19:35we the, we have a, you know, we have a doctors upset OB gyne
- 19:41doctors, primary care doctors, internists, none of them have
- 19:45had any training in hormone, in prescribing hormone replacement.
- 19:50And they don't just not comfortable with it and rather
- 19:52not do it. So that's, you know, it's
- 19:57causing misery and suffering, which is completely unnecessary
- 20:04because. In my opinion, hormone
- 20:08replacement, menopausal hormone replacement is the single most
- 20:10important medical intervention format for women of menopausal
- 20:15age. And we see tremendous
- 20:17improvements. Women are just so much, you
- 20:21know, improved quality of life and, and these are so much
- 20:25happier and, and they will, they come back to the office and they
- 20:28say thank you. And so it's, you know, you have
- 20:35to ask yourself when we touch on this in the book, who benefits
- 20:38from this fear of estrogen? You know, where's the benefit?
- 20:43Who benefits from it? And the greatest benefit I think
- 20:47is the Pharmaceutical industry because they women who have
- 20:53estrogen deficiency, you know, throughout their post menopausal
- 20:57years become very good customers of the drug industry.
- 21:02You know, for every menopausal symptom of chronic degenerative
- 21:07disease of estrogen deficiency, there's a there's a drug for,
- 21:10for osteoarthritis. The, the drugs for that joint
- 21:15replacements for insomnia, they have sleeping pills for
- 21:19depression, they have their SSRI antidepressants, which you've
- 21:25commented on many times. And, you know, goes on and on.
- 21:29They give statins for drugs for heart disease, which, you know,
- 21:34estrogen is a much better, much more effective and much safer
- 21:38and much more better approach to, to preventing heart disease.
- 21:43There's a rapid loss of bone density the first two years
- 21:45after menopause, roughly 5% a year less after that.
- 21:49You know, why should it be such a sudden rapid loss of in bone
- 21:52density? So the, the mechanism was
- 21:55suggested by a researcher from Harvard has suggested, you know,
- 22:01maybe there's this correlation between sudden decline in
- 22:05estrogen with what the sudden decline after after giving birth
- 22:11in pregnancy there there's calcium mobilized for the bones
- 22:16for breastfeeding. And perhaps that's the same, you
- 22:20know, it's an an analogy and that's why, you know, if there
- 22:25there's some mobilization of calcium from the bones causing
- 22:27osteoporosis as as a duplication.
- 22:31Of that, I mean, it's a big concern, osteoporosis, it's one
- 22:35of the main reasons I take HRT to prevent or reduce my risk of
- 22:40osteoporosis, especially of my spine.
- 22:42And the thoughts of this rapid bone loss that occurs even
- 22:45before menopause in the perimenopause years.
- 22:48I think people don't understand or don't want to understand or
- 22:52don't know what a serious condition osteoporosis is
- 22:57because it doesn't make front page of the newspapers, it
- 22:59doesn't sell the news. But it's so important that we
- 23:03think about osteoporosis. Isn't it you?
- 23:05Know, I have to tell you a story.
- 23:06When I was a medical student, my, my grandmother, you know,
- 23:11was in her 80s. And she, she asked me to look at
- 23:14her chest X-ray. So I, you know, I went to the
- 23:16hospital. I looked at her chest X-ray.
- 23:18She had this gigantic heart. She had more calcification in
- 23:21her aorta than she did in her ribs in her skeleton.
- 23:25And it was like I was struck by that.
- 23:28And, you know, that's what happens eventually to to many to
- 23:32many women. So, you know, yeah, you know,
- 23:35the the bonds have estrogen receptors and estrogen and also
- 23:41the the cartilage has estrogen receptors.
- 23:43So the estrogen is Rick is the is the best bond building and
- 23:50and together with testosterone you there are studies showing
- 23:52that when you add testosterone to estrogen, you get even a
- 23:56better bone building effect. You know the and the drugs that
- 23:59they use for the primary care docs are handing out the
- 24:03bisphosphonate drugs in that you now have newer drugs that are
- 24:10these antibody drugs that are even worse.
- 24:14I think the, the bisphosphonates are, I think, you know, all of
- 24:20these drugs are terrible drugs. You know, they cause
- 24:23osteonecrosis of the jaw. They cause spontaneous fractures
- 24:28of the mid femur. You know, the, the, the, the
- 24:34unfortunate woman is walking across the living room floor
- 24:39feel, feels a little pop in her and, and she has the spontaneous
- 24:43fracture of her femur. It's so the, these bones, the
- 24:46bisphosphonates make, they weaken the, they make the, the
- 24:51bones weaker, not stronger. And we actually have two, 2, two
- 24:56women in our neighborhood. They live down the street that
- 24:59we've known for years. Both husbands are doctors and
- 25:03they, their wives were on the bisphosphonates for five, 6-8
- 25:07years. They both develop spontaneous
- 25:09femur fractures just, you know, walking across the floor.
- 25:12So it they're bad, very bad drugs.
- 25:16So I don't recommend them for anyone.
- 25:18I mean, I people ask me, you know, what's your criteria for
- 25:21make recommending a drug? So I always say, look, if if you
- 25:26wouldn't give your dog this particular drug, then you
- 25:29probably shouldn't give it to people either.
- 25:31So, so I think that would fit that criteria.
- 25:33So, yeah, you know, the, the osteoporosis is very big.
- 25:37Women are concerned about that here in the US You know, we
- 25:40have, we have television advertising for drugs which you
- 25:43don't have in. And I think, you know, we need
- 25:45to be thinking very differently about how hormones can reduce
- 25:49future risk of diseases. So I'm very grateful for you to
- 25:53come on the podcast. I do want to cut you to come
- 25:55back to talk and in the future about thyroid because it's also
- 25:59another really important hormone.
- 26:01Before I end, I always ask for three take home tips.
- 26:04So I just want from you, if it's OK, three of the biggest reasons
- 26:11why women should consider taking hormones to reduce their risk of
- 26:14future diseases. We touched on the osteoporosis,
- 26:18you know, the bone density is a very good reason prevention of
- 26:20heart disease if you're in the 5059 age group, that's a very
- 26:24good reason. And then also, you know, we
- 26:28didn't mention another big one, which is the osteoarthritis.
- 26:31You know, cartilage has estrogen receptors and, and we've
- 26:34actually had a great experience using topical estrogen over the
- 26:39joints that are painful and the, and the joint pain does go away
- 26:43using estrogen as a topical application.
- 26:46And so I mean, those are three pigments that you know, and you
- 26:49mentioned many of your papers, the genital urinary syndrome.
- 26:54We have women who come to us, they've repeated urinary tract
- 26:56infections. So, you know, that's a terrible
- 27:00problem which they could get rid of entirely with hormone
- 27:03replacement. We use the, you know, estrogen,
- 27:05vaginal capsules, vaginal suppositories, which is very
- 27:11good for that. So that's three or 4.
- 27:14There's so many, I've been cruel asking for three, but it it's,
- 27:18it's important just to think differently.
- 27:19I think about hormones and I just really hope some of the
- 27:22conversations we're having will just change the direction for
- 27:25women and also for healthcare practitioners to prescribe them.
- 27:29People ask me, well, you know, they, they always, you know, the
- 27:33patients come into the office and say, they always, they ask
- 27:35me that all of the, they all ask the same question.
- 27:38My doctor is, is like this. They won't give me what I want.
- 27:42Why are my, why are all these doctors like that?
- 27:45And my answer is yes, they're all like that.
- 27:48They're never, ever going to change.
- 27:50And that's a good thing, because otherwise I'd have nothing to
- 27:53do. So, well, thank you so much for
- 27:56coming on the podcast today. Thank you.
