Hi
I am 43f and at the age of 18 was diagnosed with a colloid nodule on the front/right side of my thyroid, this was FNA and scanned a few more times over around a 10 year period and all fine no change. Last FNA was 2011.
Around 2017 (I think) I felt it was getting larger and more noticeable so my GP referred me back for another scan which was determined to have no changes to previous scans therefore a FNA was not requested.
The last 12 months or so I've had heightened anxiety, fatigue, stomach issues, amongst other things with all investigations thankfully returned as normal. A ANP at my GP surgery agreed a thyroid review was a good idea and blood tests were in normal range. US scan however, discovered I now have several U2 nodules on the left side and the larger right side one is graded U3. The report stated that although a U3 it still appeared no different than 2017 so no further radiology input was required. The ANP has had thyroid cancer so being very thorough wrote to endocrinology for advice. They advised no action required from them refer to ENT. I attended my appointment a week ago and had a FNA. Results will be by phone call in around 2-3 weeks.
The sonographer advised me that the U grading system only came in 2014. So my questions are;
Is the large nodule likely to have always been a U3 as it was FNA'd previously?
What are the chances of a 25 year old nodule now being cancerous?
Should I have had more regular FNA's?
Are normal TFT's a good indicator?
I'm trying to remain calm as it's not a new nodule, I've lived with it for my entire adult life. These investigations have happened because I asked for them. Just a bit concerned that I now know a bit more about grading systems that weren't around when I was first diagnosed in 1999 and wondering if I should have been a bit more pro-active.
