I saw the ENT today and he told me not to worry, that the ultrasound showed "just a cyst". He said it is septated, meaning "it just has some divisions" in it. I told him how paranoid I am since our family has been inundated with various cancers over the last 6 years. He said that cysts were nothing to worry about....it's the solid ones that are of concern. I told him that I had been doing research on the computer, and right away I could see he wasn't pleased. He told me sometimes the internet can be good, but sometimes he "hates it", because it can be misleading. I told him how I had read that ultrasounds can not be conclusive as to whether a cyst, nodule, etc is malignant or benign, so should I have a FNA. Of course he told me NO! I told him that he watched my husband's oral tumor for 6 months and even bet us his paycheck that it was benign, but it turned out to be cancer (We have yet to see his paycheck!!!!!), and that I was not willing to just watch my "cyst"! He then said he would order another TSH level (mine is 4.5 on a scale of .5 - 4.8) and he'd order a T4 level. He also said he would have me do a Thyroid Uptake, but I can not get in for that for another 3 weeks! He did not tell me the size of the "cyst", but he did have a hard time finding it when he examined me, so I'm assuming it is small. Has anyone here had a thyroid uptake test and if so, did it prove anything? Should I continue to pursue and persist, or is the doc right in that there's no need to worry for a septated cyst? I know I have been very fatigued, gained a lot of weight, have brain fog at times, difficulty swallowing, etc (some signs of Hypothyroidism), plus a lot of paranoia and anxiety about cancer! He also suggested giving me some kind of medication to lower my TSH and cause the thyroid to produce more hormone, which in turn should shrink the cyst....if it is "just a cyst", but he changed his mind and said he would have me try the medication after the thyroid uptake test. I'm trying to believe the doctor, but am very skeptical! Any help anyone can offer would be greatly appreciated!
