Chapter 23. Iodine Prevents and Treats Breast Cancer, Overwhelming Evidence

Breast Biopsy Iodine Prevents Breast Cancer by Jeffrey Dach MDChapter 23. Iodine Treats Breast Cancer, Overwhelming Evidence

Spontaneous Regression of Breast Cancer after Iodine Supplementation

In his Iodine book, David Brownstein MD reports three cases of spontaneous regression of breast cancer after iodine supplementation.(1) 

The first patient was a 63 year old English teacher.  She was diagnosed with breast cancer in 1989 and after declining conventional treatment, took 50 mg per day of Iodoral, (Iodine). Six weeks later, a PET scan showed "all of the existing tumors were disintegrating". 

The second patient was a 73 year old Delores.  She was diagnosed with breast cancer in 2003, declined conventional treatment with radiation and chemotherapy, and instead, Dolores took 50 mg of Iodoral daily. A follow up ultrasound of the breast 18 months later showed," It appears that these malignancies have diminished in size since the last examination. Interval improvement is definitely seen".   Two years later, a follow up mammogram and ultrasound failed to show any abnormality and were read by the radiologist as normal. 

The third patient was 52 year old Joyce.  She was diagnosed with breast cancer two years prior, and started on Iodoral 50 mg per day.  Three years after starting Iodoral, her follow up mammograms and ultrasound exams show decreasing size of the tumor with no progression.(1)

Iodine Deficiency Causes Breast Cancer - The Overwhelming Evidence

Human Studies of Dietary Iodine Intake

Iodine deficiency is associated with a higher rate of goiter and breast cancer.  Similarly, higher dietary Iodine intake is associated with less goiter and breast cancer.  For example, Japan has the highest dietary intake of iodine (several milligrams per day), and the lowest rates for goiter and breast cancer.  However, when Japanese women immigrate and change dietary intake of Iodine to the lower 150 mcg/day in America, breast cancer rates increase.(1)  Iceland is another country with high Iodine intake and low rates for goiter and breast cancer.  The high dietary iodine came from the fishing industry before World War One.  In those days, the fish meal was fed to dairy cows providing milk with high iodine content.  After World War One, the fish meal was eliminated from the dairy cows, and breast cancer rates soared ten-fold. (2) Iodine deficient diets in animals induces breast cancer and goiter.(1)

Important Point:

 Iodine supplementation is safe, and useful for prevention and treatment of breast cancer. 


Iodine Research from Mexico, India and Japan. 

The Shrivastava group in India reported molecular iodine induces apoptosis (programmed cell death) in human breast cancer cell cultures.  "Iodine showed cytotoxic effects in the cultured human breast cancer cells". (3)  From Mexico,  the Carmen Aceves Velasco Group reported Iodine to be safe, with no harmful effects on thyroid function, and an anti-proliferative effect on human breast cancer cell cultures. (5-7)  Their 2009 paper reported the mechanism by which Iodine works as an anti-cancer agent.  Iodine binds to membrane lipids called lactones forming iodo-lactones which regulate apoptosis (programmed cell death).  Iodine causes apoptosis which makes cancer cells undergo programmed cell death.(4) Dr. Aceves concluded that continuous molecular iodine treatment has a "potent antineoplastic effect" on the progression of mammary cancer. (10)  From Japan, Dr Funahashi reported a common seaweed food containing high iodine content is more beneficial than chemotherapy on breast cancer .   "He found that administration of Lugol’s iodine or iodine-rich Wakame seaweed to rats treated with the carcinogen dimethyl benzanthracene suppressed the development of mammary tumors. The same group demonstrated that seaweed induced apoptosis in human breast cancer cells with greater potency than that of fluorouracil, a chemotherapeutic agent used to treat breast cancer."(8)

Mechanism of Action

A 2008 paper by Bernard A. Eskin MD showed that Iodine actually altered gene expression in breast cancer cells, inducing programmed cell death. (9)  A 2003 study by Ling Zhang showed that molecular Iodine caused lung cancer cells to undergo programmed cell death (apoptosis).  These lung cancer cells had been genetically modified to increase iodine uptake.(12)  Interestingly, a 1993 case report describes spontaneous remission of lung cancer in a patient incidentally treated with Amiodorone which contains iodine (about 9 mg per day)(13)

In Conclusion: Current Iodine research calls for use of molecular Iodine for all patients with breast cancer. (10-11)  Other cancers such as lung and prostate may also benefit.  Further research on Iodine as cancer chemotherapy should receive top priority for NIH funding.  Iodine in the form of Iodoral tablets is available OTC, on the internet without a prescription.
