Positive for thyroid paroxidase antibodies and thyroglobulin antibodies. What does this mean? Had pap thyroid cancer in 2008 with thyroidectomy

Positive for thyroid paroxidase antibodies and thyroglobulin antibodies. What does this mean? Had pap thyroid cancer in 2008 with thyroidectomy

Immunity to thyroid: The thyroid makes thyroglobulin (tg) and thyroid peroxidase (tpo). Even though you had your thyroid removed, your body's immune system sees tg and tpo as foreign and has made antibodies to them. This means that following your tg as a way to monitor your thyroid cancer might be unreliable. It could also mean you have thyroid tissue that is still present in your body. Ask your endocrinologist! ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

I have hashimotos and i just got my bloodwork .Thyroglobulin is way high and I have no antibodies. Is this a sign i might have thyroid cancer?

I have hashimotos and i just got my bloodwork .Thyroglobulin is way high and I have no antibodies. Is this a sign i might have thyroid cancer?

See your doc: Thyroglobulin is only made by thyroid cells. All an elevated thyroglobulin tells you is that you have "something" going on with your thyroid. It could just be inflammation, but you can't know until more tests are done. This test is not a sensitive or specific test for diagnosing thyroid cancer. See an endocrinologist to find out more. ...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

I had a thyroglobulin antibody test taken and the results were 320. What does this mean? Should I be concerned about lupus, hashimoto's disease or thyroid cancer? I have been diagnosed with hypothyroid and the medicine I have been taking in addition to ve

Hashimoto's you have: You had become hypothyroid because you have hashimoto's thyroiditis, which was confirmed by the elevated thyroglobulin activity. You should not worry about lupus, or other conditions such as cancer. The strongest association with hashimoto's and another autoimmune problem is psoriasis and psoriatic arthritis. ...Read more

23 yrs old f; thyroid peroxidase 13 (norm); thyroglobulin, antibody 3.0 (high); TSH 10.850 (high); nomal T3 (liothyronine) & t4. Hashimotos? Possible thyroid cancer

Possible to 1st : Thyroglobulin is a test that is helpful after someone has surgery for the most common thyroid cancer. Thyroid function tests can test how well your thyroid is working. If there is concern for cancer it is helpful to get a thyroid ultrasound and then a biopsy if clinically indicated. ...Read more

If have thyroid cancer and my thyroglobulin continues to be high, should I see a cancer specialist?

Yes: If you have thyroid cancer, you should already have an endocrinologist and a thyroid surgeon on your team (and possibly a radiation oncologist also). They should work together to find the source of the elevated thyroglobulin. You might need radioactive iodine or repeat surgery. Good luck. ...Read more

Thyroglobulin was checked in april was .6 i and a papillary thyroid cancer patient. When should I retest the tg?

Variable: Most patients get thyroglobulin checked every 12 months. Every 6 months if there is a worry. I think a trend of increasing levels would be more worrisome. You and your doctors may discuss getting a stimulated level as well as radioactive iodine scan by making you hypothyroid or some may feel getting these tests with thyrogen stimulation could be done. ...Read more

Can u have reccurence thyroid cancer with no thyroglubin?

Can u have reccurence thyroid cancer with no thyroglubin?

Yes: There are different kinds of thyroid cancer, and some of them don't produce thyroglobulin. Additionally, for the kinds of thyroid cancer that do produce thyroglobulin, your body can produce anti-thyroglobulin antibodies that block the detection of thyroglobulin. A thyroid scan and/or ultrasound can help make the diagnosis of recurrence. ...Read more

Thyroglobulin Antibodies (Definition)

Thyroglobulin antibodies are proteins made by the immune system. The immune system is recognizing the thyroid as strange to the body. Thus, this is a marker of autoimmune thyroid disease. It is usually measured to confirm hashimoto's thyroiditis, but can be seen in people without significant thyroid pathology and with normal thyroid levels. It can also be seen with ...Read more

Thyroid cancer arises in the thyroid gland. It usually presents as a painless thyroid nodule. Most are papillary-follicular type and have a very good prognosis. Less common are medullary cancers, with an intermediate prognosis. Anaplastic cancers of the thyroid have a poor prognosis and are uncommon. Treatment of thyroid cancers involves removal ...Read more
