What Are Thyroid Symptoms And Their Diagnosis

 Symptoms

Thyroid cancer typically doesn’t cause any signs or symptoms early in the disease. As

grows, it may cause:

A lump (nodule) that can be felt through the skin on your neck
Changes to your voice, including increasing hoarseness
Difficulty swallowing
Pain in your neck and throat
Swollen lymph nodes in your neck
When to see a doctor
If you experience any signs or symptoms that worry you, make an appointment with your doctor.

Diagnosis

Tests and procedures used to diagnose thyroid cancer include:

Physical exam. Your doctor will examine your neck to feel for physical changes in your thyroid, such as thyroid nodules. He or she may also ask about your risk factors, such as past exposure to radiation and a family history of thyroid tumors.
Blood tests. Blood tests help determine if the thyroid gland is functioning normally.
Ultrasound imaging. Ultrasound uses high-frequency sound waves to create pictures of body structures. To create an image of the thyroid, the ultrasound transducer is placed on your lower neck. The appearance of your thyroid on the ultrasound helps your doctor determine whether a thyroid nodule is likely to be noncancerous (benign) or whether there’s a risk that it might be cancerous.
Removing a sample of thyroid tissue. During a fine-needle aspiration biopsy, your doctor inserts a long, thin needle through your skin and into the thyroid nodule. Ultrasound imaging is typically used to precisely guide the needle into the nodule. Your doctor uses the needle to remove samples of suspicious thyroid tissue. The sample is analyzed in the laboratory to look for cancer cells.
Other imaging tests. You may have one or more imaging tests to help your doctor determine whether your cancer has spread beyond the thyroid. Imaging tests may include CT, MRI and nuclear imaging tests that use a radioactive form of iodine.
Genetic testing. Some people with medullary thyroid cancer may have genetic changes that can be associated with other endocrine cancers. Your family history may prompt your doctor to recommend genetic testing to look for genes that increase your risk of cancer.
