I had a total thyroidectomy and after 10yrs my thyroid antibioties came back elevated. My tg was unmeasurable. Is this something I should be concerned?

I had a total thyroidectomy and after 10yrs my thyroid antibioties came back elevated. My tg was unmeasurable. Is this something I should be concerned?

Probably not: Did you have thyroid cancer or just a goiter 10 years ago? If no cancer, then there is nothing to worry about. You probably had positive antibodies 10 years ago as well. If you did have thyroid cancer 10 years ago and the antibodies were negative and now positive, then it's time for an evaluation. ...Read more

Tissue (Definition)

The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more

Antibody is not: Dependent on thyroid tissue. The body makes antibodies by different cells than the thyroid. The antibodies can persist even if no thyroid tissue is left. ...Read more

My thyroid us report. Right thyroidectomy. Hypoechoic nodule in isthmus.. 8 x. 8 x 1.8 hypoechoic focus in right thyroid bed. No normal tissue in r?

Thyroid ultrasound: By reporting "Right thyroidectomy" it is generally understood that the right thyroid lobe is surgically absent or has been removed. The. 8x.8x1.8 hypoechoic focus in the right thyroid bed would suggest that there is something in the soft tissues behind where the thyroid was removed that is showing up. This could be a parathyroid gland, lymph node or something else. Get back with your doctor. ...Read more

Dec 2006 total thyroidectomy for papillary carcinoma & neck dissection bc in nodes...Now us shows tissue in thyroid bed...What is it?

Residual thyroid: The surgeon cannot remove every last remnant of thyroid. This is why RAI is often given after thyroidectomy, to mop up any residual thyroid tissue-normal or cancerous. The US may just be detecting residual thyroid that the surgeon did not get. See your Endocrinologist. ...Read more

I just had ultrasound of my thyroid. I was wanting explanation of the report. I had a right thyroidectomy in 2004. The report says left lobe is normal. There is no normal thyroid tissue seen on right side. There is a tiny hypoechoic nodule in isthmus.

I just had ultrasound of my thyroid. I was wanting explanation of the report. I had a right thyroidectomy in 2004. The report says left lobe is normal. There is no normal thyroid tissue seen on right side. There is a tiny hypoechoic nodule in isthmus.

Easy: The thyroid has 3 parts. Right lobe, Left lobe and the connection between them, the Isthmus. Right side is gone, consistent with your surgery. Left side has no abnormalities seen by the ultrasound. The isthmus has a tiny nodule seen that is hypoechoic. US uses sound echos. Hypo means that it is less dense than surrounding tissue - likely fluid filled = cyst or black spot on the image. ...Read more

Had lump on thyroid biopsy came back ok. Another lump came up within 3 weeks now had partial thyroidectomy. What's the chance new lump is cancer?

Had lump on thyroid biopsy came back ok. Another lump came up within 3 weeks now had partial thyroidectomy. What's the chance new lump is cancer?

Not high: Off course the risk for someone to develop cancer will depend on different things like your personal history, your family history, history of radiation the neck area, environmental exposure etc. Majority of the thyroid nodule is benign. The risk for thyroid nodule to become cancerous is only about 5-10%. Discuss further with your doctor. ...Read more

Is it possible recurrence of thyroid cancer if thyroglobulin came back positive but antibodies are decreasing? Had full thyroidectomy 2 years ago.

Is it possible recurrence of thyroid cancer if thyroglobulin came back positive but antibodies are decreasing? Had full thyroidectomy 2 years ago.

Recurrence: Rest assured. It is impossible to say you are cancer free, but that is likely. Here's why: the thyroglobulin level is unreliable because you have antibodies. The fact that the antibodies are decreasing can mean that thyroglobulin is decreasing. Antibodies can be a tumor marker surrogate. Continue to follow the antibody trend and get periodic neck ultrasounds. ...Read more

Left over tissue: What you describe could be scar, left over normal thyroid tissue, or thyroid cancer. Ultra sound guided fine needle biopsy, +/- molecular markers and a thyroglobulin wash out can give you the answer. ...Read more

I had a hemi thyroidectomy in 2006 right side I recently had a CT of my neck for other reasons and the results came back with a heterogenous enlargement of myl left side. Should I be concerned?

I had a hemi thyroidectomy in 2006 right side I recently had a CT of my neck for other reasons and the results came back with a heterogenous enlargement of myl left side. Should I be concerned?

Need an ultrasound: If the right side was taken out and u were not placed on thyroid replacement, it's common for the left side to overcompensate & gets a little bigger. With the ct scan above, I would get an ultrasound of the thyroid to make sure there is no nodules in the "heterogenous" left lobe. If there is, u will need to follow it or get a biopsy. I assume the right was not cancerous since the left was left in. ...Read more

How does a thyroidectomy affect your thyroid levels?

Thyroidectomy: If they did a complete thyroidectomy, your thyroid levels should be low; you should become hypothyroid and need to be on levothyroxine. However, sometimes surgeons do not do a complete thyroidectomy, depending on why the surgery was done. If they did a non-complete resection, but then the thyroid gland is not normal (eg. Hashimoto's), then you may get hypo even though there is tissue left behind ...Read more

What happens to the thyroid after a partial thyroidectomy?

What happens to the thyroid after a partial thyroidectomy?

Usually nothing: About 75-80% of people who get a partial thyroidectomy remain euthyroid (have normal thyroid hormone levels) after surgery. About 20+% will need extra thyroid supplementation with thyroid hormone pills. I check everyone's thyroid function about 4-5 weeks after surgery. People may have a higher risk of hypothyroidism (low thyroid) later in life that would need thyrpid hormone supplementation. ...Read more

Should a partial thyroidectomy end the unwanted symptoms of thyroid issues? 0

Not necessarily: If your hemithyroidectomy was done to remove a thyroid nodule, the other side will still need to be monitored by an endocrinologist, particularly if it also contains nodules. Thyroid function will likely also be followed. ...Read more

Doesn't a thyroidectomy reduce thyroid hormone in the body?

Yes: Depending on how much thyroid tissue is removed, patients may need thyroid hormone replacement after surgery. Sometimes only half of the gland is removed, for example if there is concern a nodule is a cancer. These patients may not need thyroid hormone replacement. Also with goiter sometimes some of thyroid gland is left behind on purpose. More recently the entire gland is frequently removed. ...Read more

Which test is best to monitor thyroid levels in thyroidectomy patients, just ft3 and ft4, TSH and ft4, or like I feel should be tsh, ft3 and ft4?

TSH: All you really need is a tsh. Assuming there is nothing wrong with your pituitary, this hormone responds in a very sensitive manner to the levels of your T4 and t3 (liothyronine). You are presumably taking levothyroxine as replacement. ...Read more

Totally thyroidectomy 2012 2013 u/s showed nothing 2015 us showed 6mm? Residual thyroid or benign appearing lymph node. I think dr left tiny piece in

Total thyroidectomy: A surgeon doing a total thyroidectomy will always leave a small amount of tissue in order to avoid causing compications of recurrent laryngeal nerve injury or hypoparathyroidism. If thyroid cancer was found during surgery, one can get radioactive iodine to ablate the residual tissue. Finding a 6 mm nodule on ultrasound does not necessarily mean that there is recurrence of cancer. ...Read more

What does a hypoechoic non vascular round shaped nodule 7mm on thyroid bed. Post thyroidectomy. Meaning?

Not entirely clear: This means there is a "nodule" or lymph node in the area where your surgery was. If the surgeon performed a partial lobectomy, then there could be some thyroid left there and also a nodule. It could be a lymph node that was outside of where the thyroid was. Also, in reality if the surgeon did remove the entire lobe, it could be remnant scar that is being interpreted as such. Speak with surgeon. ...Read more

I had thyroid cancer less than a cm big and had a partial thyroidectomy. What are the chances that cancer could return/is already on the other side?

I had thyroid cancer less than a cm big and had a partial thyroidectomy. What are the chances that cancer could return/is already on the other side?

Yes: Thyroid cancer may come back (recur). Unlike other types of recurrent cancer, recurrent thyroid cancer is often cured, especially if it has spread only to the lymph nodes in the neck. Recurrent thyroid cancer or thyroid cancer that has spread (metastasized) to other parts of the body may be treated with surgery, radioactive iodine, radiation, or chemotherapy. ...Read more

Show it to her docto: After surgery for cancer, one needs to have follow up visits with the doctor who did the operation. The doctor can examine her and let you/her know what it is that she is feeling. If the surgeon is not available, she can go see any doctor like an internist or an endocrinologist whom she saw in the beginning of 2012 (before surgery was done). ...Read more
