Very scary that thyroid cancer has trippled in the last couple decades. Is it Fukushima? Auto-immune on the rise from GMO food? Increase in cancer therefore cancer treatment (especially radiation absorbed by the thyroid)? Increased technology should theoretically detect more nodules, but to get that test ordered by a doctor in Canada is not easy - you practically have to have a giant goitre sticking out of your neck.
