My dad has had a very aggressive form of thyroid cancer (papillary, columnar variant) that has metastasized and is terminal. I found a nodule (4.5 cm) in April, and the doctors assured me cancer was not hereditary , but it turned out to be well-differentiated papillary thyroid cancer. My doctors still try to convince me this is a "coincidence", but I feel like there has to be a connection.
Are there others that have multiple people in the immediate family with papillary thyroid cancer? What do your doctors say?
