I am about 2 months post radiation treatment. I had 35 treatments. I had a follow up ultrasound of my neck done yesterday. While no suspicious lymph nodes were found, a cyst on the left thyroid was found. It is about 1.5cm. My cancer originated on the right side of my anterior tongue. The ultrasound guy said the cyst was very vascular and that is generally a good thing. He said most of the time the cysts are just watched but because of my history they might order a biopsy. Sure enough, my doctor called me later that day and did want a biopsy of the cyst. He said they are not exactly uncommon in women my age (31) and it was most likely benign. I also have a history of hypothyroidism. Just wondering if anyone has had any similar thyroid cysts post radiation. I have read that radiation to the head and neck are a risk factor for thyroid cancer and radiation can cause other thyroid issues.

And I am going to get the biopsy to be on the safe side. After all I have been through I am now a member of the "ain't messing around crew" when it comes to stuff like this.
