I had a sonogram of my thyroid. I have 9 nodules/cyst. 2 solid hypoechoic heterogeneous nodules. What does this mean? Cancer?

Common problem: Nodules of the thyroid are common, especially in women. Most thyroid nodules are benign. "solid", "hypoechoic", "heterogeneous" nodules are the most common ones seen. If they are large enough (at least 1 cm), we typically recommend doing a fine needle biopsy to make sure they are benign. ...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

Is it true that the majority of thyroid nodules are hypoechoic and although thyroid cancer is usually hypoechoic, most hypoechoic nodules are benign?

Is it true that the majority of thyroid nodules are hypoechoic and although thyroid cancer is usually hypoechoic, most hypoechoic nodules are benign?

Size?: It is correct that in younger people thyroid nodules are benign, however, us is not very good at ruling out malignancy. Close follow up of the nodule is needed with us every 6 months. If the nodule is larger than 1 cm, fine needle aspiration biopsy needs to be considered. ...Read more

Thyroid. 6mm nodule cyst that is HYPOECHOIC Is that cancer risk? Thyroid gland self homogeneous normal size

Thyroid. 6mm nodule cyst that is HYPOECHOIC Is that cancer risk? Thyroid gland self homogeneous normal size

Likely benign: Cystic hypoechoic nodule is usually benign particularly without solid components. However some malignant tumors have cystic components. Most nodules less than 1 cm are not biopsied. Most small nodules are usually benign. Why did you get thyroid scan in the first place? Most nodules of this size are not appreciated on physical exam unless very superficial. ...Read more

I had my thyroid removed because pf papillary cancer. Sonogram shows three nodules - all small and avascular hypoechoic. They have not grown.?

I had my thyroid removed because pf papillary cancer. Sonogram shows three nodules - all small and avascular hypoechoic. They have not grown.?

Lymph nodes: Your doctor is likely surveying for the presence of enlarged worrisome lymph nodes, but the fact that they're small, uniform and lacking vasculature associated with papillary thyroid carcinoma is less concerning. Depending on the extent and subtype of your disease, continued close clinical follow up by an endocrinologist with expertise in thyroid cancer will be useful for you. ...Read more

.6mx.5mmx.3.4mm cystic thyroid nodule which is hypoechoic. Cancer risk? Grow. 2mm since 1, 5 years. Really worrying that's hypoechoic please explain

.6mx.5mmx.3.4mm cystic thyroid nodule which is hypoechoic. Cancer risk? Grow. 2mm since 1, 5 years. Really worrying that's hypoechoic please explain

Likely benign: Cystic hypoechoic nodule is usually benign particularly without solid components. However some malignant tumors have cystic components. 0.2mm growth in 11/2 years is slow growth. Most malignant tumors grow faster. Most nodules less than 1 cm are not biopsied. Most small nodules are usually benign. You are correct in getting follow up US exams. Hyperechoic lesions are denser sometimes with calcium. ...Read more

1 year thyroid nodule follow-up revealed a new thyroid nodule and the other one is no longer there. They were both hypoechoic. Chance this is cancer?

1 year thyroid nodule follow-up revealed a new thyroid nodule and the other one is no longer there. They were both hypoechoic. Chance this is cancer?

It is usually benign: The risk for a thyroid nodule to be cancerous actually is only 5-6%- and majority of thyroid nodule is benign.
Having said that, the risk of developing thyroid cancer will be higher if you have significant risk like previous exposure to radiation to the neck area at early age (childhood), family history of thyroid cancer etc.
You need to continue to f/u with your doctor and sono as indicated. ...Read more

Hi I have a family history of thyroid disorders and thyroid cancer. I have a isoechoic nodule on my left lobe measuring 23x18x16mm and a iso slightly hypoechoic nodule on isthmus measuring 11x5x9mm. The larger has a rim of vascularity and internal vascula

Endocrinologist can: You will benefit from seeing and being guided by a Thyroid specialist (called Endocrinologist).
A fine needle aspiration (FNA) biopsy may be required to determine if the nodules in your thyroid are benign or could be cancerous. Seek medical advice and obtain a second opinion if U R not satisfied and want to be sure/ want more certain guidance. ...Read more

I had a ct scan of neck, they saw small hypoechoic nodule in thyroid and an enlarged lymphnode, is it cancer?

Thyroid nodules: This is a very common finding, and the fact that it is small suggests lower risk. Usually under 1 cm they don't bother to biopsy, but perhaps with an enlarged LN in the area it might need it. Fine Needle aspiration biopsy can be safely and easily done perhaps with US guidance and a pathologist to evaluate the sample to ensure it is sufficient and triaged to the appropriate next steps. Most r b-9 ...Read more

Thyroid nodule at 3.4 x 4.7 x 2.3cm. Blood tests confirm all is normal. Ultrasound shows heterogeneous iso/small area hypechoic. Chances of cancer?

Yes, some: You need to see an endocrinologist. Who would likely do a fine needle aspiration (fna) biopsy. Thyroid cancer needs to be ruled out by further testing. It has to be a consideration in your case. But thyroid cancer is easily treatable and highly curable (>95%). ...Read more

What does it mean when thyroid has a focus with irregular contour. What is a hypoechoic focus measuring. 08×0.4cm? Is this cancer?

What does it mean when thyroid has a focus with irregular contour. What is a hypoechoic focus measuring. 08×0.4cm? Is this cancer?

Nodule: There is likely a nodule with irregular shape or border. This is very common. The size is very small. No need to worry at this point. Likely all you need is another ultrasound 1 year from now to make sure it's not growing. Chances are it will stay the same. Good luck. Don't poo poo it away but no need to excessively worry. Just follow it. ...Read more

What does "very hypoechoic nodules with increased vascularity" mean? Is that indicative of cancer? Nodules are not 1cm. The larger one is 0.40cm x 19cm

Nodule: Hypoechoic generally means that the lesion is more likely to be cystic (contains fluid), however, increased vascularity is concerning. Depending on the history, location and presence of other symptoms fine needle aspiration for cytological analysis or a biopsy should be considered. Watch for alternative points of view from other physicians ...Read more

Is my complex thyroid nodule taller than wide? It's 12 mm x 6 mm x 5 mm? Does this mean cancer?

Is my complex thyroid nodule taller than wide? It's 12 mm x 6 mm x 5 mm? Does this mean cancer?

In order: To determine whether the nodule is taller than wide, you need to specify the orientation of those measurements: Anterior-posterior (AP), transverese (T), and longitudinal. If the AP/T ratio is greater than 1, the nodule is taller than wide. An A/P >1 does not necessarily mean cancer, but along with other features, may indicate the need for FNA biopsy. ...Read more

Does calcification in thyroid nodules mean that you have cancer?

It depends: It depends upon the pattern of the calcification. "eggshell" calcification, where there is a thin calcific rim around the the nodule is not associated with an increased risk of cancer, while "microcalcifications" inside the nodule are associated with a much higher risk of cancer, 50-100%, compared to 5% for nodules in general. ...Read more

What does 7mm nodule on thyroid bed jest medial to carotid mean? I had a thyrodectomy 2 years ago for thyroid cancer. Can this be another cancer?

Recurrence: This may be an area of residual thyroid tissue or may represent spread to lymph nodes in the central neck region, the most common area for thyroid cancer lymph node metastasis. A serum thyroglobulin may be elevated if this is related to your thyroid cancer and a thyroid cancer may be detectable on I thyroid scan. An ultrasound guided fine needle biopsy can make the diagnosis. ...Read more

My friend has a nodule on the right upper lobe & a hypodense lesion on her right thyroid lobe, so does that mean if she has cancer it is spreading?

No: Hypodense lesion is an ultrasound term that describes the appearance of a thyroid nodule. Most thyroid nodules are hypodense, and most of these nodules are benign. If it is over 1 cm in size, fine needle biopsy of the nodule should be considered to determine if it is benign or not. ...Read more

I have a tyroid nodule, 1.6 x. 9 x 3 cm. Heterogeneously attenuating predominantly cystic right thyroid nodule. What's it mean and could it be cancer?

Thyroid: Its highly unlikely to be cancer. The odds favor this being a thyroglossal duct cyst. Pts often present at you age. You don't say where exactly your mass is. TDC is usually near midline. Another possibility is a branchial cleft cyst which is also a congenital problem. Your docs may want to do a CT guided fine needle biopsy. Hang in there. I think you will be fine. ...Read more

What does multiple hypoechoic focus nodules mean on my thyroid? What is parenchymal inhomogeneity?

Varying appearance: Inhomogeneous means areas of different echogenicity or density rather than homogeneous where entire gland has same density. Hypoechoic means areas with decreased density or less echoes which often are cystic. As long as any nodular areas are not larger than 1 cm in diameter they usually do not require biopsy. ...Read more

My 7 year old son was diagnosed with multiple cysts on his thyroid. One nodule is7x7x5mm and hypoechoic among other masses. What does this mean?

Pediatric center: Nodules are not the same as cysts. Patients with hashimoto's thyroiditis can have multiple small nodules. Sometimes it's just best to have these studies interpreted by thyroid-specialized radiologists. You could start by seeing a pediatric endocrinologist who will most likely want the ultrasound repeated in another facility more specialized. ...Read more

Why do thyroid cancers form nodules?

Why do thyroid cancers form nodules?

Cell growth: Nodules are another word for a mass. Cancers generally form masses. About 20% of the population have thyroid nodules at some point during their lives. About 70% are benign; of the remaining 30%, 80% are papillary thyroid carcinoma, which is a very low aggressive form of cancer to have. Follicular, medullary and undifferentiated carcinoma make up the rest, with some rare types. ...Read more
