Thyroid nodules are usually benign (non-cancerous) tumors. However, some nodules may become cancerous in rare cases. A thyroid nodule is a growth or lump on your thyroid gland. It can be felt as a swelling or a hard, non-tender lump under your skin. An ultrasound scan or X-ray can help establish the location of a thyroid nodule. You cannot tell whether a thyroid nodule is cancerous or non-cancerous just by looking at it. A Newport beach thyroid nodule biopsy is required to establish if a thyroid nodule is malignant or benign.
A thyroid biopsy is an important tool in the diagnosis of thyroid disease. The procedure involves removing a small tissue from a thyroid nodule and sending it for microscopic analysis. A biopsy can help confirm the presence of an overactive thyroid gland or identify whether there is an abnormality such as cancer.
Here are instances when you need a thyroid nodule biopsy;
A nodule that exceeds 1 centimeter
If you have any concerns about the size of a thyroid nodule, be sure to have it biopsied, even if it is small. The surgeon may need to remove more tissue than needed to see if there is anything else in your thyroid.
A nodule that moves or is changing shape
A change in shape or location can indicate cancerous growth and should always be biopsied. As with any change in shape, it’s important to keep track of how often this happens so that you can report it back to your doctor.
A nodule that becomes tender or painful
A tender nodule may indicate a problem with nearby lymph nodes or be the first sign of an underlying medical condition such as an infection or autoimmune disease. If this happens, get medical attention so your doctor can diagnose and treat the problem quickly.
What are the different types of thyroid biopsies
Fine-needle aspiration
This procedure is the most common and least invasive method of collecting cells from a thyroid nodule. It involves placing a needle into the nodule and aspirating it using a syringe to collect material for examination under a microscope. The needle is then removed, leaving a small incision in the skin.
Radioactive Iodine Ablation (RAI)
This procedure uses radioactive iodine to destroy or destroy and kill any cancer cells present in a thyroid nodule. This method may be used if fine-needle aspiration does not result in enough tissue or if RAI is unavailable at your institution.
Magnetic resonance imaging (MRI)
This method uses magnetic fields and radio waves to produce cross-sectional images of organs and tissues inside the body. It can provide information about the extent of inflammation in your thyroid and the presence of lymph nodes near your thyroid gland, which may indicate cancerous growth.
Thyroid nodule biopsy is a method of obtaining tissue from the thyroid gland. The tissue is then examined to see if it contains cancerous or precancerous cells. A thyroid nodule biopsy can determine whether the presence of a tumor has been diagnosed correctly and whether it needs treatment. This will help ensure that your doctor prescribes the correct treatment for you. For more information, consult Dr. Sean P. Nikravan, MD, FACE.
