Can anaplastic thyroid cancer be found on ultrasound?  Is the nodule or appaerance solid, cystic or both.  Would the radiologist be able to tell?

Tissue diagnosis: A diagnosis of anaplastic thyroid cancer would require removing part or whole of the lesion/nodule and examination by a pathologist. Radiology has not progressed enough in resolution to make this diagnosis. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Does medullary thryroid carcinoma will show anything on an ultrasound? Nodules or tumor will be visible? Can it be present in a normal looking thyroid

Does medullary thryroid carcinoma will show anything on an ultrasound? Nodules or tumor will be visible? Can it be present in a normal looking thyroid

Resolution of U/S: Hi. Like all imaging modalities, there is a limit to what you can see with U/S looking at the thyroid. All cancers begin as a single cell gone bad that clonal expands (bear in mind possibility of multiple independent foci of MTC such as in MEN2's and FMTC), so at some point in their infancy, all MTC cancers are below the limit of resolution on U/S. Once nodules are biopsiable, FNA helps evaluate. ...Read more

Are there signs of thyroid cancer on ultrasound?

Are there signs of thyroid cancer on ultrasound?

Yes: Solid thyroid masses that are large, have characteristic internal calcifications, irregular borders, increased blood flow on doppler ultrasound, and/or enlarged lymph nodes in the area are generally concerning for malignancy. However, when we biopsy these nodules with a needle most turn out benign. ...Read more

How well does a thyroid ultrasound tell if you have cancer or not?

Pretty good: The thyroid ultrasound does not directly tell you if you have cancer. The ultrasound identifies suspicious areas of the thyroid. Then, if the areas are suspicious enough, you may undergo a biopsy where a needle is placed into the thyroid area and samples are examined under a microscope to see if you have thyroid cancer or not. ...Read more

My thyroid ultrasound showed mutliple nodules. Does that sound like cancer?

My thyroid ultrasound showed mutliple nodules.  Does that sound like cancer?

Multinodular thyroid: The most common cause of your ultrasound finding is a multinodular goiter. Majority of time these are benign and the thyroid will have normal function. It is actually more of a concern for cancer when the thyroid only has 1 or 2 solid nodules, not dozen of smaller ones. A thyroid biopsy is a simple test to sample suspicious nodules. ...Read more

My thyroids are enlarged. My labs and ultrasound are normal, however now there is a dull pain. I'm 28. Should I worry about cancer?

My thyroids are enlarged. My labs and ultrasound are normal, however now there is a dull pain. I'm 28. Should I worry about cancer?

No: If the ultrasound is normal without nodules or masses, i wouldn't worry about thyroid cancer. The dull pain might be inflammation, lymph node from recent infection, sore throat, muscle tension...But don't worry about thyroid cancer right now. ...Read more

Had my thyroid removed related to cancer. Current ultrasound read "no significant residual thyroid tissue identified" should any tissue be remaining?

Had my thyroid removed related to cancer. Current ultrasound read "no significant residual thyroid tissue identified" should any tissue be remaining?

Not with ablation: Sometimes microscopic tissue remains and usually is detected by scanning with i123 or i131, radio tracers, that are taken up by thyroid tissue. Usually with cancer no tissue is desired and is usually destroyed by combination of surgery and radio iodine therapy. ...Read more

Thyroid ultrasound question: what do cancer's look like on ultrasound?

Thyroid ultrasound question:  what do cancer's look like on ultrasound?

Darker than normal: Ultrasound shows differences in density of thyroid nodules. They many times seem darkerthan normal thyoid tissue. Sometimes you can see increased amount of small blood vessels. Sometimes you can see small specks of calcium. ...Read more

I had ultrasound done on my thyroid. Nurse said that I have a 3.8cm mass , she also said cyst but isn't sure hypo eccentric. Could it be cancer?

I had ultrasound done on my thyroid. Nurse said that I have a 3.8cm mass , she also said cyst but isn't sure hypo eccentric. Could it be cancer?

Wait: And get the final findings from the radiologist, not the nurse or technician doing the ultrasound. Confirm the size is in cm and not mm. Thyroid cysts are generally benign. See your doctor who ordered the test to follow up with the final radiologist's report ; their recommendations for possible treatments. ...Read more

Can cancer of throat neck or thyroid be seen on an ultrasound?

Can cancer of throat neck or thyroid be seen on an ultrasound?

Possibly: An ultrasound only tells you that there is something there. Throat cancer is often easily seen by an ENT exam. However, an ultrasound can tell if a lymph node has an abnormal architecture possibly because it is infiltrated by tumor. Thyroid nodules that are hypervascular, hypoechioc, or contain calcifications on ultrasound are more likely to be malignant. For neck or thyroid mass see ent. ...Read more

I'm a 39 year old male. A thyroid nodule was found during an ultrasound. % chance of cancer?

I'm a 39 year old male. A thyroid nodule was found during an ultrasound. % chance of cancer?

It depends: There are many factors which affect a given nodule's risk of being a thyroid cancer. These include size, and other features visible on us (ultrasound) and patient age. Because women have many more being benign thyroid nodules than men, the risk for any one nodule is higher in a man. For a typical 1-2 centimeter (1/2-3/4 inch), that risk might be about 4% in a woman, or about 8% in a man. ...Read more

Will medullary thyroid cancer always show in a thyroid ultrasound ? If not how do they find it?

Will medullary thyroid cancer always show in a thyroid ultrasound ? If not how do they find it?

Thyroid cancer: Hello. Unfortunately cancer of the thyroid will not show up on an ultrasound. A nodule or a growth in the thyroid can be seen and identified. A tissue or needle biopsy is needed to examine the cells for cancer. An excisional biopsy if needed will provide the pathologist the entire gland which then will be examined and a diagnosis rendered. ...Read more

What the chance of hypoechoic nodules in thyroid ultrasound is cancer in a 40 years old female?

How large do thyroid nodules look on ultrasound in order to raise suspicion for cancer? Does size matter?

How large do thyroid nodules look on ultrasound in order to raise suspicion for cancer? Does size matter?

Size matters: Size does matter. Thyroid nodules of less than 1 cm are usually insignificant. Among nodules of >1 cm, the likelihood of cancer increases with size, but even bigger nodules (3-4 cm) are usually benign. Best approach: US and fine needle aspiration should be done by someone experienced in interpretation, usually an Endocrinologist. If surgery needed, find an experienced thyroid surgeon. ...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


Anaplastic (Definition)

This largely relates to cancer cells and is a description of how variant the structure and division pattern is from normal cells. An anaplastic cells has weird internal componens, sometimes extra nuclei, and a bizarre pattern of division. They are usually more rapidly dividing and are a serious type of abnormality ...Read more
