Thyroid medication increases your risk of breast cancer

Print Friendly, PDF & Email

pill-schedule(NaturalHealth365) Today roughly 27 million Americans, 80% of them women, suffer from “thyroid disease” (a.k.a. hypothyroidism), 14 million in the form of Hashimoto’s thyroiditis, which is also an autoimmune condition. In addition, more than 60,000 were diagnosed with cancer of the thyroid just last year.

Exactly why there is an epidemic of hypothyroidism in this country can span many subject areas, including public policy. What doesn’t get enough air time, however, is what happens to most individuals after they receive a diagnosis of thyroid imbalance. The truth is: Most are prescribed thyroid medication, with dire consequences.

Conventionally-trained doctors continue to push prescription medication without a solution

Sometimes when a thyroid imbalance is severe, taking a synthetic medication for a certain period of time can help stabilize a dangerous situation. This should always be a short-term solution, however.

Synthetic drugs should never replace natural ways of regulating the thyroid, including nutrition, stress management and supplementation – especially the use of iodine.  Unfortunately, most doctors are all too happy to write a prescription for the most common thyroid medication out there – Synthroid.  Plus, the biggest mistake, most physicians never test for common underlying issues, such as iodine deficiency.

Thyroid medication becomes a ‘best-seller’ drug

It is not wonder that Synthroid, produced by Abvie Inc., is the most prescribed medication in the nation, with a little over 23 million people currently using it. Proponents of the drug says that it mimics the body’s natural production of thyroxine (T4).

A further look, however, suggests that Synthroid (i.e. levo-thyroxine) may not be all it’s cracked up to be. First of all, there are the known side effects, which include:

  • Weight loss
  • Tremors
  • Headache
  • Vomiting
  • Diarrhea
  • Irritability
  • Insomnia
  • Fever
  • Menstrual cycle changes
  • Temporary hair loss
  • Chest pain
  • Rapid or irregular heartbeat

In addition, Synthroid is not the same as thyroxine (T4) – a hormone that is produced naturally in your body; in terms of structure and function, the two are vastly different. After all, if they were “identical,” as proponents of the drug claim, how could it be patented?

Plus, Synthroid’s synthetically-produced T4 may actually be blocking the body’s natural use of thyroxine. The synthetic version competes with natural T4 hormones for cellular receptor sites. This may be one reason why most people who are prescribed Synthroid will be on it for life.

Finally, Synthroid only replaces T4 hormones. Your body has to convert these to T3, or triiodothyronine, which is the biologically-active form of the hormone. Many people have a hard time converting the synthetically-produced T4 hormone to T3. T3 conversion can also be hampered by factors such as selenium deficiency, low omega-3 fatty acids, low zinc levels, environmental toxins and stress.

Difficulties with synthetic T4 to T3 conversion is also one of the reasons why it is so difficult to find the right dose for the drug.

The Synthroid-Iodine deficiency connection to breast cancer

The worst consequence about long-term thyroid medication use, however, is its direct link to cancer, especially breast cancer.

“Nearly every physician in the United States will reach for a prescription pad to order thyroid hormone when he sees a patient with goiter or symptoms of hypothyroidism,” says Dr. Jim Howenstine, MD, an internal medicine specialist. “This can be exactly the wrong thing to do if the patient has deficient stores of iodine.”

A study conducted by Ferdinand-Sauerbruch Hospital in Wuppertal, Germany found that women taking thyroid medication were twice as likely to develop breast cancer as women who were not taking synthetic thyroid hormone replacement. What’s more, 20% of the women who had taken this medication for 15 years or more had developed breast cancer. Those who had taken it for 5 years had only a 10% incidence of breast cancer.

The reason for the discrepancy is simple. Conventional medicine is treating the wrong thing when it comes to thyroid issues. This same study compared the results of iodine therapy to that of Synthroid for individuals who had goiter.

Concerned about breast cancer? Don’t become iodine deficient

After 8 months, both treatments led to a reduction in goiter size. Both treatments were then suspended. After four months, the iodine-therapy group had normal-sized thyroid glands while the Synthroid group saw their goiters return to pre-treatment levels.

There is a direct link between low iodine levels, hypothyroidism and breast cancer. This is because the mammary glands have a “trapping system” for iodine just like the thyroid gland does. Glands in the breasts compete with the thyroid gland for needed iodine.

90% of the world’s population is iodine deficient. Less iodine in the body equals less iodine for hormonal distribution in both the breast area and the thyroid. It was once commonplace for bread manufacturers in the United States to supplement their dough with iodine.

In the 1960’s, that practice was eliminated and bromide, a highly toxic substance that is known to directly affect the thyroid gland, was substituted instead. Is it any wonder that the incidences of thyroid-related conditions, especially Hashimoto’s, has skyrocketed over the last fifty years and that the rates of breast cancer in the U.S. also went from 1 in 20 to 1 in 8 during this same time period?

The first step: Get tested to protect yourself from breast cancer

The good news is that when your body is receiving enough iodine to do its job, depleted systems can become vibrant and healthy again in a relatively short period of time. The first step, however, is to get tested.

I suggest completing a 24 Hour Iodine-Loading Test, which will check for both iodine deficiency and the existence of bromide in your system. The test will also ensure that you are supplementing with the proper amounts of iodine.

    I like so many women have taken this junk. It doesn’t work the doctor has to keep adjusting the dose and trying other medication alone side of it.

    Very few people are aware that a slightly slow thyroid is tied to longevity. This is a know fact, which is not known by most doctors.

    This is one of the conditions that is over-treated. A dietary change can get as much results as medication.

  • Dorothy Jones

    Most elderly people have a slower thyroid, which is somewhat natural. Yet, in the retirement community I live in it seems every other person is on a thyroid medication.

  • Christine P

    I went to a doctor and told him some of my symptoms and he offered me a prescription for a thyroid medication without any testing. After reading this all I can say is thank goodness I declined the prescription.

  • Russ Torres

    Just to be clear a slow thyroid is getting to be more common, just as all thyroid conditions. The question should be what is causing it?

  • Wendy Allen

    Synthroid has gluten in the filler? Gluten may make antibodies to the thyroid. Microscopic gluten may hurt people. Celiac maybe the root cause to thyroid issues and may hurt other glands. TSH may not help to know about thyroid since the pituitary may also be affected that makes TSH. Zinc/Se/enough iron/probiotic may help convert T4 to T3. Any food with a label/certified gluten free food/nuts not sold with a label/meat basting/some spices and more may have hidden gluten.

    I like this article, however what to do in a situation when the Thyroid has been destroyed through radiation? I have spoken with several natural doctors and they told me in my case I cannot substitute because my thyroid has been partially destroyed and it is not a low function. I am taking iodine in addition. Does anybody have thoughts about this? I would love to switch but at this point have not found anybody that was able to find another product for me.

  • Tonya Mullins

    Any suggestions for someone that has to be on medication after having the thyroid removed due to thyroid cancer? I’m currently on Synthroid and hate it.

  • Sundaram

    Yes, but they will treat practically any condition you ever get, over 3000 or 3500 diseases are in their frequency list. I have improved my health a lot using a machine. I consider it an investment in my health. So the one-time cost is worth it for me and my friends who use it too.

    I appreciated this article even though I have never taken Synthroid as I heard too many negatives about it from natural healer friends. I have taken Armour for about six years now and while I have had to go from 30mg to 45mg over the course of that time, I’ve never had any problems other than the common complaint of ‘lack of energy’. The M.D. who gave me my marijuana recommendation for stress and interrupted sleep, suggested that I try Lugol’s Solution, which is a nascent iodine. It was developed in Germany about 100 years ago but with the advent of technology, was forgotten about. The doctor promised me that it would be a “life changer” by taking only three drops a day. My gut told me to follow his advice so I found it Online and his words were prophetic! Without increasing my Armour any further, Logol’s Solution gave me back my energy and I even dropped a bit of weight! Of course, this is just my own personal experience. I know we are all different but I’ve shared this with friends and they, too, have had a positive result!

    BTW, I live in So. Calif. and with the elevated radiation levels from Fukushima, (SP?)

    I’m glad to be taking the iodine!
