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

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

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

3cm hypoechoic solid vascular thyroid nodule with a cluster of hurthle cells, fna benign, follow up ultrasound now shows microcalcifications. Cancer?

3cm hypoechoic solid vascular thyroid nodule with a cluster of hurthle cells, fna benign, follow up ultrasound now shows microcalcifications. Cancer?

Not necessarily...: The fact that FNA was reported as benign, the nodule is unlikely to be malignant. Small droplets of benign colloid often mimic "microcalcificatins" of papillary tumor, hence caution is advised. I would suggest repeating the FNA, and consider also collecting samples for gene profiling studies, such as, those manufactured by Veracyte and Asuragen (Note:I have no financial/other interest.) ...Read more

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

Less than 1cm hypoechoic thyroid nodule disappeared one month later.Dr said 1st ultrasound wasn't overread. How'd it disappear?

Thyroid nodule: Thyroid cysts can certainly come/go. The quality of ultrasounds, the interpretation, and the definition of a "nodule" can vary. Hashimoto's can cause a patchy pattern that can look like a nodule. Certainly a small nodule that is so transient is not something to worry about. An endocrinologist should be able to interpret things. ...Read more

Why do I need another ultrasound after biopsy for thyroid nodule?

Why do I need another ultrasound after biopsy for thyroid nodule?

If it was inconclusi: If it wasn't a good sample, was inconclusive, or another biopsy needs to be done to obtain tissue for an afirma genetic assay. Ask your doctor. Biopsies cannot 100% prove the absence of cancer. ...Read more

Why do I need another ultrasound after biopsy for thyroid nodule i had an ultrasound ten days ago?

No: Not unless there has been a significant clinical change or another biopsy is required. Repeat biopsy will be necessary at intervals to evaluate progress and possible therapies. ...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


Nodule (Definition)

Any growth or deposit in the body or on its surface may be casually termed a nodule until its character is determined by the familiarity of the physician with it or by the results of a biopsy if it is not so obvious. The term is casual ...Read more
