From The Doctor’s Desk: Stress Is a Doorway to Disease

Seasons has hosted, on several occasions, Dr. Eldred Taylor, an international expert in bioidentical hormones. During his speaking engagements in Ruston, he talked with men and women about lots of exciting ways to help manage their health. Dr. Taylor is a talented teacher, and I want to share the way he taught our patients about stress and hormones.

Stress elicits a hormonal response, he explained. In fact, 75%-90% of all primary care doctor related visits can be directly attributed to stress according to the Journal of the American Osteopathic Association. It makes sense. When you are stressed, you are more prone to illness. That’s one effect of hormones, specifically cortisol.

Stress is a doorway to disease if it’s not treated and corrected.

Here’s what I mean by that. In nature, a zebra or horse running from a predator has acute stress response. Does the stress have a negative effect on the animal’s body? Sure. But the animal is running for its life. Either one of two things happen. The animal will get away, and the stress will end. Or the animal will die… and the stress will end. Either way, the animal is not going to suffer from constant stress.

But in contemporary society, many of us suffer from constant stress. When we experience stress, we too have a surge of hormones to help us fight or run away. You’ve heard of fight or flight. When we are running from a predator, everything works fine. The hormones activated by stress pump us full of energy, and we escape the predator. Or kill it.

But in contemporary society, sometimes we can’t kill our predators or run away from them. Sometimes our predators are coworkers or bosses. We don’t get along with these people, or perhaps we are intensely competitive, and it causes stress. Only we can’t escape these predators in the same way that a zebra can escape a lion. We have to fight with that coworker or boss every day. We experience the stress every day. Our bodies weren’t designed to handle this kind of chronic stress.

That’s why it’s so important to relax. Learn to control what you can. Learn to let go of the rest. I highly recommend things like aroma therapy and massages for relaxation. That’s why Seasons has developed a medical spa—because we want to do more than just help people who are not well. We want to help prevent people from getting sick in the first place.

Stress management is a good place to start.

Who’s Afraid Of The Big Bad Bioidentical Hormone?

What is Progesterone? Do women need progesterone after a hysterectomy? Does it cause cancer as some have been told? Does it disrupt the thyroid as some also have been told? What is truth? What is fiction? What does the evidence show?

Let’s work through some of these questions systematically.

What is Progesterone?
Progesterone is the hormone a woman’s body produces after ovulation each month. It balances the effect of estrogen in the uterus and throughout the body. When everything is working well in your body, estrogen and progesterone balance each other to create a normal menstrual cycle. However, when progesterone levels fall and estrogen dominates, a woman can experience heavy bleeding, irregular cycles, PMS, weight gain…

Some folks would have you believe that synthetic progestins (especially Provera) are identical to progesterone. This just isn’t true. They are not similar in http://ww5.komen.org/, structure, or function. Progestins and progesterone do both protect of the lining of the uterus from excess estrogen. But that is where the similarities stop!

Race for the Cure… and a Better Understanding of Women’s Health
Breast cancer research has received a lot of attention lately through wonderful campaigns like Race for the Cure, Breast Cancer Awareness Month, and similar efforts. All of this research has given us some wonderful insights into women’s health in general. Specifically, the research has revealed clear distinctions between bio-identical progesterone and synthetic progestins.

Numerous large studies have shown that synthetic progestins, such as Provera, increase a woman’s risk of breast cancer. In contrast, bio-identical progesterone can reduce a woman’s risk of breast cancer. This has been clearly tested and consistently confirmed. In fact, just having low progesterone levels makes a woman 5.4 times more likely to get premenopausal breast cancer. Even worse, such women are significantly less likely to survive a fight with breast cancer.

As a doctor, I am horrified by these statistics, and I want to help—through my own practice and through an attempt with many other doctors to educate women.

As a scientist, I am amazed that something as simple as progesterone deficiency results in a higher breast cancer risk.

Still Not Convinced?
Here’s a quick summary of the down and dirty science. Estrogen is a powerful stimulant to breast cell growth. (Remember, cancer is unregulated cell growth). When researchers added synthetic progestin, the growth of breast cells increased significantly. In contrast, when researchers added progesterone, breast cell growth decreased by 400%.

And here’s what that means. A woman’s body needs progesterone even after a hysterectomy. Progesterone doesn’t cause cancer—in fact, the opposite is true! Finally, a woman’s thyroid is not disrupted by progesterone—again, the opposite is true!

Progesterone is safe. Women’s bodies produce it for a reason. They need it.

Bioidentical Hormones: What Does The Scientific And Medical Evidence Say?

A young lady came into my office the other day to discuss hormones. She was a breast cancer survivor. Her concern, and rightly so, was her risk of getting breast cancer again. Since she lived in the south (our main office is in Ruston, Louisiana), she had experienced the women’s ritely passage of menopause: “the hysterectomy ceremony.”

Her question to me was: can she take hormones? Years ago, her cancer doctor had placed her on premarin, telling her that it was safe. She also was told that because she had a hysterectomy, progesterone was not necessary. Her gynecologist, in contrast, told her she couldn’t take premarin. Different doctors, different opinions.

I’m not trying to offer a third opinion here. I just want to stay focused on the evidence. That is what evidence-based medicine is all about. Unfortunately, market forces are clouding evidence-based medicine today.

In earlier posts, I’ve talked about progesterone, synthetic progestins and their polar opposite effects on a woman’s breasts. Progesterone lowers risks. Progestin increases risks. I want to get a little more specific today with some information from an outstanding review of the evidence. In Dr. Kent Holtorf January 2009 article, the Bioidentical Hormone Debate, he exhaustively reviewed 196 research articles. (If you aren’t up to reading the full article, you can read an abstract of the review.)

Here is my summary of the risks associated with synthetic progestins:

• increased breast cell growth
• increased conversion of weaker estrogens into more potent estrogens
• promoted the formation of toxic estrogen metabolites (16-hydroxyestrone)
• stimulated the conversion of inactive estrogen to active estrogen (estrone sulfate to estrone)
• had anti-apoptotic effects. (Apoptosis is programmed cell death: which is a way to control cancer growth. Anti-apoptosis means your body lacks this method of controlling cancer growth.).

Contrast this with the benefits of the natural bioidentical hormone progesterone.

• reduced breast cell growth by 400%
• downregulated estrogen receptors in the breast
• induced cancer cell apoptosis (programmed cell death that helps control cancer growth)
• reduced breast cell division and growth
• and in some studies, progesterone actually arrested human breast cancer cells.

After looking at nearly 200 independent studies, Dr. Kent Holtorf concluded that “Both physiological and clinical data have indicated that progesterone is associated with a diminished risk for breast cancer, compared with the increased risk associated with synthetic progestins.” Studies have shown that synthetic progestins increase the risk of breast cancer:

1. by approximately by 25% for each 5 years of use
2. by triple the risk (67%) of breast cancer when added to estrogen therapy
3. double the risk to 4% per year when compared to estrogen therapy alone.

This is in stark contrast to bio-identical progesterone, which reduces the risk of breast cancer by 10%.

“As far as the east is from the west”—that is how different the effects of progesterone and synthetic progestins are on the breast. Holtorf concludes his article in Postgraduate Medicine with statements like this: “With respect to the risk for breast cancer, heart disease, heart attack, and stroke, substantial scientific and medical evidence demonstrates that bioidentical hormones are safer.”

In my next post, I’ll look at synthetic premarin versus bioidentical hormone estrogen.

From The Doctor’s Desk: Hormone Imbalance A Contributing Factor In Breast Cancer

Hormone Replacement Therapy (HRT) increases breast cancer. Have you read headlines like that? Or perhaps you were told that HRT caused someone’s breast cancer.

Do hormones really cause or lead to breast cancer? Think about this: every women continues to produce hormones, even after menopause. So, it cannot be that hormones in and of themselves cause cancer. Scientific evidence indicates that synthetic hormones and hormone imbalance do contribute to breast cancer.

The ABC’s of Estrogen.

Estrogen’s effects in the body are regulated through two different kinds of receptors: alpha and beta receptors. Estrogen-alpha receptors stimulate breast cell growth. Estrogen-beta receptors inhibit breast cell growth.

• Estradiol, the most potent estrogen, equally stimulates alpha and beta receptors = growth stable
• Estrone, the second most potent estrogen, stimulates alpha receptors 5:1 over beta receptors = pro growth
• Estriol, the weakest variety of estrogen, actually stimulates beta receptors 3:1 = growth inhibitory

The key element here is balance of hormones. Higher levels of estrone present in your body (produced by fat cells) result in more breast stimulation. Higher levels of estriol present in your body results in less breast cell stimulation and, therefore, breast protection. Estriol = Good. Estrone = Bad. If you have heard of someone developing breast cancer after starting Premarin, there’s a logical explanation for that. Guess what Premarin is loaded with? Premarin contains (48%) estrone (estrone = bad = breast cell stimulation).

Here are some more ugly facts about Premarin, also know as conjugated equine estrogen. Premarin actually decreases estrogen beta receptors. So, if you take Premarin, then you are taking high doses of estrone (estrone = bad) and decreasing your estrogen receptors that inhibit breast cell growth. In a nutshell: you are taking more of the bad estrogen and decreasing your amount of the good estrogen. This equates to a prime set up for breast cancer.  Don’t take my word for it. See the wonderful article by Kent Holtorf.

Progesterone: The Growth-Inhibitor Hormone

The confusion out there about estrogen and breast cancer is bad enough, but the confusion is even greater on the subject of progesterone.

Pregesterone is the key hormone in the second half of a woman’s cycle. Estrogen is the dominant hormone in the first half of your cycle (estrogen = growth = growth of the uterine lining to support implantation of an egg). The counteractive hormone to this growth phase is progesterone (progesterone = no growth = sloughing off of the uterine lining). It’s the amazing and fascinating way that woman was created.

Synthetic progestins, often prescribed, are NOT the same as the progesterone your body produces. Just look at the structure and you see that they are not. The one thing they do have in common is they both protect the lining of the uterus against excessive estrogen growth. But, that is where the similarities end.

While there are many differences between the two, our focus here will be on the difference in breast cancer potential. Simply stated, synthetic progestins are pro-breast cancer and bioidentical progesterone is breast protective. The Women’s Health Initiative (link) revealed a 26% increase in breast cancer as a result of taking synthetic progestin. The Nurse’s Health Study (link) found that synthetic progestins tripled breast cancer risk over that of estrogen only. The use of Provera, a synthetic progestin and component of Prempro, has been shown to increase the risk of breast cancer by 800%!

The statistics for bioidentical progesterone are the opposite. Bioidentical progesterone has many positive breast benefits:

• Progesterone decreases estrogen production
• Progesterone moves estradiol to weaker estrone
• Progesterone moves estrone to inactive (sulfated) form
• Progesterone moves estrone to weakest/safest estriol
• Progesterone down-regulates estrogen receptors all together
• Progesterone activates the cancer protection gene, p53

The idea that progesterone is a safer alternative to synthetic progestins is not new at all.  As early as the early 80’s, there has been a call for safer progesterone over synthetic progestin counterparts. In 1981, nearly 30 years ago, L.D. Cowan showed that just having low progesterone levels increases the risk of premenopausal breast cancer risk 5.4 times.

Unfortunately, progesterone-deficient states, (or estrogen dominance) are very common in women today as a result of many factors: being overweight, PCOS, environmental xenoestrogens, excessive estrogen therapy, and perimenopause. Another study, showed progesterone to have a 400% decreased breast growth rate.

The Scientific Evidence Is Clear.

The evidence in the scientific literature is clear with regards to estrogens, progesterone, and hormone balance.
