According to Dr. David Brownstein, the reason breast cancer appears in the area of the lymph nodes is that they are very close to the iodine receptor sites. Both women and men have six receptor sites in their bodies. Women have three in their breast tissue, one in their thyroid and two in the ovaries, while men have the thyroid, two in the breasts, one in their prostate and two in their testes.
These receptor sites cannot differentiate between any of the halogens and will accept anything to keep itself running, whether it is Flourine (toxic), Bromine (also toxic) & Chlorine (toxic).
Back in the 60’s Iodine used to be in bread flour as a caking agent, but was removed following concerns about radioactive iodine used in medicine. Since that time, the increase in breast cancer and goiter have increased exponentially.
I have no argument with your supposition concerning the elimination of sweating, as it most likely does play a role in immune suppression. There are certainly many possible links to breast cancer, but Iodine has proven to be helpful across the board in treating and stopping cancer of the testes, prostate and breast cancer.
