Iodine and breast cancer prevention

Print Friendly, PDF & Email

(NaturalHealth365) The role of Iodine in the prevention (and treatment) of breast cancer is gaining much needed attention. Women with hypo-thyroid conditions – and taking thyroid medications – appear to be twice as likely to develop breast cancer compared to women not taking thyroid medications. Since Iodine is essential for hormone production, a deficiency in this element can affect many systems in the body.

Has your doctor taught you how to prevent cancer?

Over a century ago, Iodine was known as “the universal medicine” since it is essential for life. Every cell in the body contains and utilizes Iodine in many pathways such as:

• Hormone production
• Nerve and muscle function
• Metabolism
• Tissue growth and repair
• Cellular respiration

Given the various functions of Iodine in the body, it is easy to see how even a slight deficiency can cause widespread problems. It has been estimated that approximately one third of the world’s population is Iodine deficient, and studies in the United States have suggested that the number may be even higher, with some estimates as high as 95%.

Cancer causing substances in your home

Iodine deficiencies can occur not only because of inadequate intake, but also due to damaging toxins called Halides. These include chemicals like bromide, chloride and fluoride. Bromide, for example, is used as a flame retardant in mattresses and clothing as well as for fumigation and the treatment of swimming pools and hot tubs.

These chemicals actually compete for Iodine on a cellular level, and the chemicals always win. An especially interesting area of study in Iodine deficiency is the field of hormone balancing. Over twenty years ago, The Lancet reported that Iodine deficiency predisposes one to an increased risk of breast, endometrial and ovarian cancer.

Hormonal chaos can promote cancer growth

Iodine is a crucial ingredient in the delicate balance of the endocrine system, and deficiencies have been associated with conditions such as polycystic ovarian disease (PCOS), fibrocystic breast disease and increased breast cancer risk.

Promising research has been conducted on the use of Iodine and its effect on fibrocystic breast disease and breast cancer. Healthy breasts have a concentration of Iodine in the breast tissue, but if there is a deficiency, the thyroid and breast tissue compete for the Iodine.

If the deficiency is chronic, then hyperplasia, or increased cell growth occurs, resulting in fibrocystic breast disease. If the Iodine deficiency persists, estrogen production increases with an Iodine deficiency, creating an increased sensitivity to estrogen in the breast tissue.

Get tested and take action

On the flip side, sufficient levels of iodine actually induce breast cancer cell death by activating specific enzymatic pathways. In order to determine the daily amount of essential Iodine required for whole body sufficiency, a “24 hour Iodine Loading Test” must be performed. This test is based on the premise that the more Iodine-deficient the body is, the more ingested Iodine is retained, and the less Iodine is excreted in the urine.

Assessing Iodine levels is key to lowering the risk for developing breast cancer since the identification and treatment of Iodine deficiency has obvious benefits. Once you receive the lab results, supplement appropriately, if needed, with both Iodine and Potassium Iodide.

    What is a well assimilated iodine
    supplement that u would recommend?

  • Ingo Spalthoff

    I like this article. What all articles alike fail to mention is that special attention has to be shifted to toxicity and detoxification from heavy metals. To give an overview, EVERYONE shall try and take 5 Gram Chlorella Pyreneidosa algae every day. That dosage is enough to mobilize but not enough to detox the mobilized metals. 5of10 of the global population get heavy metal related symptoms like dizziness, insomnia irritated skin, depression within a day or two.

    That shall be an example of how the situation is when it come to toxification and heavy metals. Any article aiming at better health that does not mention what I just expressed, has to be considered des-info. The importance of this issue can not be over-articulated.

    Anyone interested may at best start a google-search here: dr klinghardt (with either ‘Lyme-induced-Autism’, ‘Mercola’, ‘Let’s talk real Health’, ‘protocols’, ‘vita’, …and alike)


  • Harvey Vedder

    thx; great info; I passed this on to a friend who spends inordinate time in a chlorine laden pool.
    We find in our clinic that too often body pH is compromised, resulting in an acid body condition that makes absorption of iodine difficult or even impossible.

  • Reza

    Thank You very much for giving this news about iodine and its role in breast cancer development. Because it is very important trace element in cell function, then its deficiency can be involment in other diseases.I have a question from Author: Dr. Veronique Desaulniers:You say that low levels of iodine cause an increased sensitivity to estrogen in the breast tissue,can we say this effect may be occur for prostate cancer development because aberrant leveles of sex hormons have role in its development?

  • Ingo Spalthoff

    Let me just add, that Klinghardt says a very good breast cancer treatment is a few drops lugolsche solution on a tampon over night. When it comes to acidity in the tissue it may also be connected to heavy metals. Tissues develop a low ph, kind of as a last attempt to handle the toxins when every other mechanisms of detoxing them fails. In any event, you’d be better advised to not listen to me rather than to listen to the Videos and interviews Klinghardt has given frequently over the years.

    Iodine is – as it seems to me – best to be taken from the logol solution. It is cheap as chips and medically accepted for decades.

    Dr. V
    Glad to see you are spreading the word about iodine. I believe it is one of the most important reasons I have been able to regain and retain my health after breast cancer. I have been taking over 50mg daily for the past few years and it has helped me to detox, lose weight, and even got rid of a festering plantars wart I had had for decades.
    Harvey-please encourage your friend to start swimming in pools that do not contain bromine or chlorine. I too was once a swimmer and I believe this was a major contributor to getting breast cancer. The toxic halides (bromine, chlorine and fluoride) will take over the receptor sites for iodine if one is deficient and end up causing all kinds of health problems.
    I have a lot of information archived on my website, about iodine. I am also starting a discussion group for iodine if anyone is interested:
    Let’s all keep spreading the word about the benefits of iodine!

    Hi Reza,
    There is some literature and studies about prostate cancer and iodine. the iodine tests are simple to do and reasonably priced. You can learn more about the 24 hour iodine loading test on my web site:

    What level of iodine is good? No one ever says what the numbers should be. Docs are so often just looking in a book and telling you what the AMA says is the right level and those are so far removed from reality that I would like to see a real, honest number for iodine level. I am a 40 year type-1 diabetic and trying to do everything I can to stay healthy. There is a history of breast cancer in my family so any preventative measures I can take, I will.
    Thanks for the info!

    Bottom line is your tumor suppressing genes just won’t work without iodine

    For a long time I suffered with very cold hands and cold feet. I had umpteen pairs of slippers for the winter! I started taking high amounts of Nascent Iodine (cause it doesn’t taste as bad as the other kinds…) I took about 8000-16000mcg per day. Did this for about 6 months. And I am happy to say that I did not have to wear slippers once this winter. My hands and feet have finally stopped feeling like icicles! I don’t take Iodine to that extent anymore, but give my self a really good dose occasionally so I don’t get low. What started me on that path, was an article a read a few years ago about how Bromide, chloride, and fluoride all compete with Iodine, and Iodine always looses because it’s not as strong. Bromide is pretty much now in all bread items, and many people are consuming large amounts of Bromide. I did have my thyroid tests done before hand. All of my results were right in the middle of the reference range, except TSH, which was in range but on the low side.

  • Robin Rosen

    Dr. V –
    I have been taking Synthroid for years, and my mother died of breast cancer, and one of my sisters has had a double mastectomy. I have recently (past year) decided to be proactive and not reactive about my health – have become a vegan, take a fair amount of supplements, and overall am really trying to change my lifestyle! I just started taking iodine this past week. Can I safely choose to just get off the levothyroxine and supplement iodine instead. It is the only medication I take, and I would love to get off of it. Thanks so much for your input.

  • Millen

    I have hypo-thyroid condition and take thyroid medication every day… Although I knew about importance of iodine for my condition and overall health, i didn’t realize the extend of this importance. Thank you, doctor V for this reminder! Great information.

  • Jane Dsouza

    Somewhere I think that the breast cancer or any type of the cancer can be prevented with the help of natural herbs and medicine or also using the best Ayurveda medicines. The side effects like nausea, vomiting, tiredness, mouth ulcer , etc which are caused while taking treatment for breast cancer like chemotherapy and radiation, these side effects can be lowered and can be reduced with the use of Wheat-grass powder.

    Hi Vicki,
    when you do the 24 hour Iodine Urine Loading test the normal ranges are:
    Initial urine spot test before iodine supplementation: 0.1 -0.5 mg/L
    After the Iodine dosage the spillage in the urine should be greater than 45 mg in 24 hours.
    I hope this helps clarify your question.

  • Dr. V

    Hi Robin,
    Before you make a decision about the medication and the Iodine, make an informed decision. Do the 24 hour urine iodine test to see if you are deficient and have some blood work done to determine how your thyroid is functioning. If you need any more direction or help, feel free to contact me directly through my web site.

    Is this test covered under the regular blood tests and I am also from Canada. is the test under the same name. I would like to be tested just had op for EGFR and the surgery has affected the breast on the sidewhere the lund was removed. This could mean prevention for me as well as all the naturalpath I am doing, can you advise.
