"I would like to tell you my thoughts on breast cancer and thyroid disease in an abbreviated form. Breast cancer takes around 20-30 years to develop. The discovered lump represents the end stage of slow cancer progression over decades. The longest period is the first phase of cancer development. This phase which is often called pre-cancerous happens as as a normal cell is gradually turned into a cancer cell. These pre-cancerous lesions are known as fibrocystic disease (lumpy, tender breasts) of the breast. (2-3,13-14) Most fibrocystic disease is benign, harmless and has no consequences.
"On the other hand, some more advanced forms of fibrocystic disease have clearly defined tendencies towards breast cancer. So there are grades of fibrocystic disease with some of the cells looking more abnormal than in the benign forms. The greater the difference in the cells from normal (abnormal) the greater chance of these cells converting to a cancer cell over 10-20 years. So if you have fibrocystic disease still at the age of 45-55, you likely have had this for many years. There maybe then a significant chance the cells may change into a cancer cell. The good news is that it can be cleared up completely with a daily intake of iodine.(9)"
"If it is true there has been a general decrease in salt intake and thus iodine intake since the 1950s, there should have been a general increase in the number of women with fibrocystic (lumpy) disease of the breast. But if as well even lower iodine intake was occurring in the female population, worse forms of fibrocystic disease would occur which are statistically directly related to breast cancer. The chances of getting breast cancer then go up considerably. Now if we put this together with the incidence of breast cancer going from 1 in 23 in the mid 1960s to 1 in 8 currently then it seems to fit together. Over the last 80 years hundreds of publications have confirmed statistical correlations between the worse forms of fibrocystic disease of the breast and subsequent breast cancer. Unfortunately if you have fibrocystic disease you really don't know what type you have without a biopsy. On the other hand if you take iodine in adequate amounts daily all of the fibrocystic disease disappears so that you are essentially preventing breast cancer from occurring. If a cancer has already started it is unlikely it will be stopped with the iodine at that dose.
"From my personal investigations cancer is roughly divided into two phases. The first part is the pre-cancerous phase (before cancer) and involves the change of a normal cell into a cancer cell. This first phase of cancer development takes about 10-30 years. Iodine in adequate doses stops and reverses this stage of the cancer process by causing the natural death of abnormal cells (apoptosis). Iodine circulates throughout the body in the extracellular fluids found between the cells of the body. If cell surface proteins have the amino acid tyrosine on the outside, the passing iodine reacts with this tyrosine. This little reaction denatures the protein and thus kills the cell. It is implied all 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. This would then expose the tyrosine to the iodine passing in the extracellular fluid. Again the iodine would denature the protein by reacting with the tyrosine and thus kill off the cell. So thus we have surveillance system for removing abnormal cells from our bodies. On the other hand low iodine intake allows cells to proceed and develop towards cancer. This is more indirect because the gradual increase in abnormal cells are just not being eliminated from the body because there is inadequate iodine to carry this out.
"Once the cell has become a cancer cell then it can take two different turns. It can multiply and spread or it can multiply and just stay where it is. The second is called carcinoma in situ. (cancer at the site) The second phase (cancer multiplying and spreading) is the part we are all familiar with. Since on average breast cancer cells double every 100 days, it takes 9 years before mammograms can pick it up and around 11 years before we find it ourselves. (15)
"This second clinical part of the cancer phase (the spreading) seems to be arrested by adequate levels of thyroid hormone in all tissues. Thyroid hormone completely controls the connective tissue which forms a strong sieve-like barrier to the passage of cancer cells trying to spread.(16-18) Low levels of thyroid hormone in the tissues (especially connective tissues) promotes the spread of cancer cells. So the body cancer defense system has two parts iodine for the first pre-cancer phase and thyroid hormone and iodine together for the second clinical phase. There is some overlapping of these two defense systems. The excess iodine flows out in the urine. Of course, because the iodine flows out in the urine it is preventing the development of abnormal cells in the bladder and kidney system at the same time. This then prevents cancers developing there."
"An adequate dose of iodine can be defined as more than 4 mg per day. Lugol's solution is an iodine-in-water solution used by the medical profession for 200 years. One drop (6.5 mg per drop) of Lugol's daily in water, orange juice or milk will gradually eliminate the first phase of the cancer development namely fibrocystic disease of the breast so no new cancers can start. It also will kill abnormal cells floating around in the body at remote sites from the original cancer. Of course this approach appears to work for prostate cancer as prostate cancer is similar to breast cancer in many respects. Indeed, it likely will help with most cancers. Also higher doses of iodine are required for inflammatory breast cancer. As well we know that large doses of intravenous iodine are harmless which makes one wonder what effect this would have on cancer growth."
