They removed the mole but found that it did spread to his lymph node and the dye also showed in a nearby gland. The lymph node was removed and part of the gland for testing. They didn't take the whole gland yesterday because of its proximity to a nerve that runs from the spinal cord to the face. Nicking it would clearly be bad.
Regardless of that outcome he will need the nodes in his head and neck checked via u/s every four months to make sure it hasn't spread further.
So we will know more in about ten days. Thanks for the good vibes yesterday!
