From The Doctor’s Desk: The Moral of the Story? Hormone Balance Key To Reducing Breast Cancer Potential.

I have four kids that range in age from four to eleven. One of my favorite things to do is read them a great story. So today, let’s talk about some very important stories and the moral each one presents.

The story about breast cancer potential has more characters than just estrogen and progesterone as we discussed in my last post. There are other hormones that are integral characters in that story also. As you will learn in this post, the moral to the breast cancer story is balance — balance between all the hormones in your body.

The Story On Dehydroepiandrosterone (DHEA) — Say That One Three Times Fast!

DHEA, a testosterone precursor, is a hormone produced by the adrenal glands and plays a part in breast protection. DHEA plays an important role in supporting the immune system. DHEA stimulates the production of good T-helper lymphocytes-1 and their associated good cytokines: interferon, Interleukin-2 and Tumor Necrosis Factor-beta. This is in contrast to the bad T-helper lymphocytes-2 and their bad cytokines. DHEA levels typically decline as we age. The decrease in DHEA levels are inversely correlated with increasing age-related disease. The strength of this correlation is yet to be determined, but the decline in immune system due to low DHEA is clear. So where does that leave DHEA? Individuals with low DHEA levels have more disease, and in this case, more breast cancer. The moral of this story? Low DHEA = a compromised immune system = breast cancer vulnerability.

The Story On Melatonin — The Sandman Hormone.

Melatonin is the hormone that regulates your sleep cycle. It is produced from the pineal gland in the brain. Low melatonin levels have been linked to breast cancer through the additional benefits of melatonin. Melatonin boosts the immune system, decreases estrogen and progesterone production, and acts as an anti-oxidant. Bench studies (non-human studies) have shown significant increase risks of breast cancer with low melatonin levels. Can you guess what happens as we age? Yes, you guessed it. Our melatonin levels fall. Ever talk to a post-menopausal woman? Most women of that age have sleep-related complaints. The moral of this story? Low melatonin = a compromised immune system = breast cancer vulnerability.

The Story on Thyroid — The Energy Hormone.

How about the thyroid hormone?  The breast cancer link reaches to all hormones and everything seems to involve the thyroid these days! T4 (or better known as synthroid, levoxy, levothryoixine) is one of the most prescribed medicines today. But T4 is a very weak thyroid hormone. In fact, the body is looking for T3, a result of T4 to T3 conversion. The problem is that many individuals don’t convert T4 to T3 well. (Very often I see patients who have been on synthroid for years without symptomatic improvement even though their “levels” are said to be “good”.  I digress. That’s a subject for another post. Let’s get back to the breast cancer link.) Low T4 and T3 levels result in low sex hormone binding globulin levels (SHBG). SHBG is how some hormones are transported. When SHBG levels drop, the free availability of the hormone it transports goes up. In this case, the levels of free estradiol go up. Remember the negative breast implications of estrogen dominance from last weeks post (link)? The moral of this story? Low thyroid = low SHBG = high estradiol = estrogen dominance = breast cancer vulnerability.

The Story On Insulin — The Sugar Storer

Finally, Insulin. Insulin’s primary role is in the storage of glucose. However, due to the large percentage of simple or refined sugars in our diet, insulin resistance has become a major epidemic, and, yes, insulin resistance increases the risk of breast cancer. How, you ask? High simple sugars leads to insulin resistance and PCOS (Polycystic Ovarian Syndrome). As a result, estrogen dominance and excess testosterone are produced which leads to weight gain. Remember that fat cells produce even more estrogen and estrogen stimulates breast cell growth (link). Young women will start their cycles at an earlier age and thus will increase their lifetime exposure to estrogen without appropriate progesterone balance. And to make matters worse, traditional therapy with birth control pills for these young women increases the breast cancer risk even further. The moral of this story? Insulin resistance = estrogen dominance = breast cancer vulnerability.

Change The Ending Of The Story.

Just because any of these hormone deficiencies might produce in you symptoms which you recognize in this post doesn’t mean that you are going to have breast cancer. However, the sooner you seek hormone balance, the quicker you are going to lower your breast cancer vulnerability/potential. As you can see, the hormonal symphony is what is important. Balance! When your hormones are balanced, the result is a symphony, and in turn, your body is in tune and makes beautiful music. But when your hormones are not balanced, then…well, you know the ending of that story.
