Iodine Displacement by CFCs, Radiation and Cancer

Nascent iodine protects us from cancer.  CFCs displace native iodine from receptors in cells and cancer risk increases as a result.

Sunlight has abundant cancer-causing UV radiation.  Is there an association between iodine and protection from radiation?

Yes!  The classic defense administered in cases of radiation poisoning is iodine. 

Again, sunlight is a major risk for cancer.  The iodine association strengthens this hypothesis.
