High resolution ultrasound can detect a diagnosis of papillary thyroid cancer spread to lymph nodes as small as 1-2 mm (the size of a tip of a ball point pen). When looking at the lymph nodes in the neck with ultrasound, the following are important criteria which may lead to a FNA needle biopsy to confirm disease.
Can you see thyroid cancer on an ultrasound?
An ultrasound may show your doctor if a lump is filled with fluid or if it’s solid. A solid one is more likely to have cancerous cells, but you’ll still need more tests to find out. The ultrasound will also show the size and number of nodules on your thyroid.
What can show up on a thyroid ultrasound?
Because ultrasound captures images in real-time, it can show the structure and movement of the body’s internal organs. The images can also show blood flowing through blood vessels. An ultrasound of the thyroid produces pictures of the thyroid gland and the adjacent structures in the neck.
How can thyroid cancer be detected?
The actual diagnosis of thyroid cancer is made with a biopsy, in which cells from the suspicious area are removed and looked at in the lab. If your doctor thinks a biopsy is needed, the simplest way to find out if a thyroid lump or nodule is cancerous is with a fine needle aspiration (FNA) of the thyroid nodule.
How can you tell if a thyroid nodule is cancerous?
The only way to definitively determine if a thyroid nodule is cancerous is to examine it under a microscope. The most common method is called fine need aspiration (FNA) biopsy, where a very small needle is inserted into the thyroid nodule and cells are removed for microscopic examination.
What are early warning signs of thyroid cancer?
Signs and Symptoms of Thyroid Cancer

What are the symptoms of thyroid problems in females?
Hypothyroidism signs and symptoms may include:
- Increased sensitivity to cold.
- Dry skin.
- Weight gain.
- Puffy face.
- Muscle weakness.
Can you have normal thyroid levels and still have thyroid cancer?
Most thyroid cancers will have normal T3 and T4 levels. High calcitonin levels are often seen in medullary thyroid cancer. A blood protein called CEA may also be elevated in those with this form of cancer.
What are thyroid cancer markers?
A thyroglobulin test is mostly used as a tumor marker test to help guide thyroid cancer treatment. Tumor markers, sometimes called cancer markers, are substances made by cancer cells or by normal cells in response to cancer in the body. Thyroglobulin is made by both normal and cancerous thyroid cells.
Where Does thyroid cancer spread first?
Most patients with thyroid cancer have the cancer contained in the thyroid at the time of diagnosis. About 30% will have metastatic cancer, with most having spread of the cancer to the lymph nodes in the neck and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.
Does a thyroid biopsy hurt?
The biopsy causes very little pain. But your doctor may need to put the needle into your thyroid more than once. This is done to be sure enough fluid and tissue is taken for the test. The doctor then looks at the tissue sample under a microscope for cancer, infection, or other thyroid problems.
Can thyroid make you feel like something is stuck in your throat?
