I've had mine tested every 6 months due to nodules that keep growing...luckily, thyroid cancer is a very slow growing cancer and the cure rate is extremely high. I only have the left side of the thyroid since my right side test was inconclusive on a fine needle biopsy and the only way to make sure is to remove it and test it...

Grant me the senility to forget the people I never liked,the good fortune to run into the ones I do,and the eyesight to tell the difference.
