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.

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

I still have high thyroid perox AB levels after a thyroidectomy (cancer). Are high levels normal or could there be some thyroid tissue still? Thx

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.

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.

Radioactive iodine?: Did you ever have a radioactive iodine ablation to get rid of remnant tissue? Residual tissue in the thyroid bed could be remnant tissue or recurrence.

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.

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.

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.

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.

I've had total thyroidectomy & neck dissection & 2 rai treatments, ultrasound found tissue in thyroid bed, what does this mean?

I've had total thyroidectomy & neck dissection & 2 rai treatments, ultrasound found tissue in thyroid bed, what does this mean?

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.

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.

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

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.

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

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.

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.

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?

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.

Thyroidectomy 3 years ago, when they check my levels are they checking just my thyroid or vitiamin d also?

Thyroid: Vitamin d is a separate blood test and will need to be ordered individually by your physician.

Two hours: Does depend on any prior scarring, procedures invasion, and speed of the particular surgeon- very careful, is the key since important adjacent structures.

What determines if I need rai treatment after thyroidectomy? I have two nodules which are pappilary thyroid cancer.

What determines if I need rai treatment after thyroidectomy? I have two nodules which are pappilary thyroid cancer.

Depends: Most of the time after thyroidectomy recurrences are treated with rai, but not always younger people surical removal is preferred choice, you have to discuss with your oncology team which is the best method for that particular person.

What are the normal thyroid lab test values status post total thyroidectomy? W/o any meds

What are the normal thyroid lab test values status post total thyroidectomy? W/o any meds

TSH 0.5-3: Thyroid level recommendations are the same with or without a thyroidectomy and regardless of medications. The TSH should ideally be between 0.5-3.
