Alinc,

Dr.John Duillard clears this issue up in his excellent article:
"Iodine Supports the Lymphatic System
=======================================
According to Ayurveda, Iodine is a natural lymph mover. When the lymph becomes congested, certain lymph sensitive tissues react. The breasts will swell during menses, which indicates that lymph drainage from the breast is compromised. When the lymph becomes congested, the cells cannot remove their waste and the white blood cells in the lymph and the immune system become stuck in traffic. This can make the breasts toxic because they are an area of lymph concentration.

When the lymph system slows down, the affected tissues improvise because they can’t bring in new oxygen-rich blood. If the body loses adequate blood flow – often due to poor lymph drainage – the ovaries may become cystic, the uterus can accumulate fibrous tissue, the breast can become lumpy or the muscles will become filled with fibrous scar tissue (a tissue that doesn’t use very much blood to function) that may cause pain with movement.
