“Breast cancer today is not what it was 20 years ago. Survival rates are climbing, thanks to greater awareness, more early detection, and advances in treatment,” Although this is the case, prevention is still better than cure. Here’s how you can use iodine to treat and prevent breast cancer.

Iodine plays an important role in your body as it reduces the thyroid hormone, kills fungus and bacteria. But, it’s also an effective cancer treatment and prevention.

Here’s how iodine works to help treat cancer

According to Dr Wright of Nutrition & Healing, iodine kills breast cancer cells without killing off normal cells in the process. And that’s why it’s ideal for both the treatment and prevention of breast cancer.

It’s most effective when you literally put the treatment right onto the problem.

How to administer iodine as a breast cancer treatment…

“Mix a solution of 50% iodine DMSO and rub it directly onto your breast as near as possible to where the cancer is (or used to be). The DMSO will ensure penetration deep into the tissue,” says Dr Wright

If you’re worried about breast cancer spreading, you can also rub the mixture into the area under the arms that’s rich in lymph glands (nodes) where breast cancer spreads first.
While a DMSO solution is available in your local health shop, Dr Wright cautions you NOT to use iodine without consulting a physician skilled and knowledgeable in the use of high-dose iodine.

“Also be sure that your physician monitors your thyroid function and gives you other nutrient suggestions while you use iodine as an adjunct to your regular breast cancer treatment,” Dr Wright advises.

  • The pre-cancerous phase

(The development of abnormal, benign cells)

  • The first, long-term, pre-cancerous phase, is when normal cells gradually become abnormal cells – g. the discovered breast cancer lump represents the end stage of a slow development over ~20-30 years. The pre-cancerous lesions (lumpy, tender breasts) are known as FDB (Fibrocystic Disease of the Breast).


Appropriate and natural destruction of cells that represent a threat to the integrity of the organism – E.g. cancer cells and virus-infected cells.

Essential to growth and development – E.g. Fingers form in the fetus by apoptosis of the tissue between them;

  • When normal cells are damaged beyond repair, they are appropriately eliminated by apoptosis – the programmed or natural death of damaged, infected or malfunctioning cells.
  • Cancer cells avoid apoptosis and continue to multiply in an unregulated manner
  • Adequate Iodine stops and reverses the pre-cancerous stage of the cancer process by causing the natural death of abnormal cells(i.e apoptosis) –preventing them from becoming cancer cells. Sites of rapid apoptosis in the body are also sites with highiodine

Inadequateiodine in a tissue allows abnormal cells to persist, allows cysts to grow, and may eventually lead to cancer

  • Dose to Prevent and Eliminate Pre-cancer cells? –An adequate dose ofiodine to prevent pre-cancer phase (abnormal cells) may be defined as more than 3-4 mg / day. One drop of Lugol’s in water, juice or milk or ½ an Iodoral tablet (6.5 mgiodine/iodide) should both prevent cells from changing into cancer cells and gradually eliminate pre-cancer cells, so no new cancers can start. It will also kill abnormal cells floating around in the body at remote sites from the original cancer.

(2) The multiplying phase of cancer

(a) Cancer cells can multiply and just stay where they are (carcinoma in situ)

or (b) Cancer cells can multiply and spread (metastasis)

On average, breast cancer cells double every 100 days,

and it takes ~9 years before mammograms can pick them up.

  • Adequate thyroid hormone (produced by a normal thyroid with sufficientiodine),prevents the spread of cancer cells to other organs – The amount of thyroid hormone present in tissues controls the strength of connective tissue, which forms a strong sieve-like barrier to the passage of cancer cells trying to spread.

Iodine – Supplementation

  • When there is sufficient thyroid hormone present, then the cancer cannot spread – Conversely . . .imagesCARLG2QK

A low level of thyroid hormone in the tissues (especially connective tissues)

allows cancer cells to spread

  • Adequate Iodine Dose to Prevent Cancer Spread? – You should do your own research on this. However, this author has so far found that the available literature indicates a dose of about 50mg iodine/iodide (8 drops 5% Lugol’s Solution or 4 Iodoral ®) /day in split doses) according to tolerance, with the goal of achieving whole bodyiodine sufficiency (~1.5 g) in about 3-6 months.
  • Brownstein said he was using 200 to 300 mg with his prostate and breast cancer patients- with those who have metastases needing the highest dosages.
  • There is some overlapping of the two iodine defense systems -in the pre-cancer and multiplying phases.

How does iodine eliminate abnormal cells?

  1. δ-Iodolactone is the main mediator for preventing cancer – this iodinated form of lactone (produced when iodide oxidizes polyunsaturated lipids) seems to be the main iodocompound which can inhibit growth and induce apoptosis in human thyroid carcinoma cell lines (B-CPAP cells, FTC-133 cells and 8505C cells) as well as on human breast cancer cells (MCF-7). Also, human lung cancer cells with genes spliced into them that enhanceiodine uptake and utilization undergo apoptosis and shrink when giveniodine, both in vitro and implanted in mice.

  1. Iodine may also kill abnormal cells by the same method it destroys single-celled microbes –by reacting with exposed tyrosine. Once the thyroid gland has becomeiodine-saturated, most of the rest of the availableiodine in the body then circulates throughout the body bathing the extracellular fluids found between body cells. If cell surface proteins have the amino acid tyrosine on the outside, the passingiodine reacts with this tyrosine. This reaction denatures the protein, and by disturbing the cell membrane, it thus kills the cell (This is the same chemical reaction by which iodine in dilute solutions causes the death of single-celled microbes – bacteria, viruses, fungi, and protozoa).

Healthy vertebrate cell membranes do not have tyrosine on the portion of the protein sticking out into the extracellular fluid. However, the intra membrane proteins may have tyrosine which is only exposed when the membrane is distorted by abnormal cell development such as we see in the pre-cancerous forms of Fibrocystic Disease of the Breast (FDB). This would then expose the tyrosine to theiodine passing in the extracellular fluid, enabling theiodine to do its work and kill off the cell.

AdditionalIodine roles in preventing cancer

  • Any excess iodine flows into the urine -preventing the development of abnormal cells in the bladder and kidney system, and thus also prevents cancers in those locations.
  • Theantioxidantproperties of iodides have a role in cancer prevention – by their ability to markedly quench the high-energy, excitedsinglet oxygen to its less reactive triplet form, thus preventing singlet oxygen from causingoxidative damage to DNA.

  • Iodineis a powerful deactivator of environmental chemical toxins– cancer-causing suspects, E.g.xenoestrogens, pesticides, herbicides, industrial chemicals;

The Overwhelming Evidence ofIodine against Cancer

  • Spontaneous regression of breast cancer seen in 3 cases supplementing iodine

Please visit the following site to read information on these cases where iodine supplementation has shrunk tumors in the breast:

  • Supporting evidence foriodine deficiency involvement in breast cancer, fibrosis and painful breasts in FDB patients

Breastcancerchoices.org lists several of iodine’s impressive abilities against cancer:

  • Desensitizes estrogen receptors in the breast;
  • Reducesestrogen production in overactive ovaries;
  • Reduces fibrocystic breast disease – which often precedes breast cancer;
  • Causes more cell death than the chemo drug, Fluorouracil;
  • Prevents rats from getting cancer when fed the breast cancer causing toxin DMBA.
  • A deficiency of iodine is a known factor in the development of prostate cancer

1950’s article links deficient thyroid activity with cancer rates

  • Data from 15 countries in four continents give support to the importance of local factors to account for the known local variations of cancer incidence -Iodine availability, traced by goiter incidence, appears to be one of such factors. Closer scrutiny of some of these countries corroborates these conclusions.
  • Presence of thyroxine in the tissues has been amply demonstrated in animal experiments to bring about a tissue environment that is unfavorable to tumor growth and development -at least as long as tumors remain in the dependent phase.

Estrogen/Iodine Connection

  • Iodine metabolizes carcinogenicestrone and estrogenmetabolite 16-α-hydroxyestrone –► “anti-carcinogenic”estriol;
  • Iodine desensitizes estrogen receptors in the breast;
  • Iodine reducesestrogenproduction in overactive ovaries;

Mainstream medical treatments are not working

Breast cancer incidence worldwide has increased from 1 in 23 in the mid-1960s

to currently 1 in 8, and is increasing by ~1% each year

  • Mortality rates not improved with today’s technology – surgery, chemotherapy, mammography, and radiation have not altered the mortality rate since record-keeping began in the 1920’s.85% of women who develop breast cancer will die of causes directly related to breast cance
  • Radiation and chemotherapy to the breast can affect the thyroid gland – radiation to the breast for prevention of local recurrences can affect the thyroid gland. The thyroid gland in your neck is in close proximity to your breast and depending on the angle used by the radiation machine, the dosage used and also how good the machine is at preventing radiation scatter, the radiation can have both short and long term effect on your thyroid gland health. Chemotherapy (including Tamoxifen) delivers toxic compounds and can have side effects on many organs including the thyroid gland. The combination of chemotherapy and radiation can lead to clinically obvious low thyroid
