Video - Thyroid nodules and thyroid cancer: Pathology review
00:00 / 00:00
Video Summary
Thyroid nodules are lumps or growths that form in the thyroid gland, which is located in the neck. Thyroid nodules are relatively common and are often benign. They may cause no symptoms and be discovered incidentally during a physical exam or imaging study, or they may cause symptoms such as difficulty swallowing, hoarseness, or a visible lump in the neck.
Thyroid cancers, on the other hand, are less common than benign thyroid nodules, but the incidence of thyroid cancer has been increasing in recent years. There are several types of thyroid cancer, including papillary thyroid cancer, follicular thyroid cancer, medullary thyroid cancer, and anaplastic thyroid cancer.
The risk factors for thyroid cancer include a family history of thyroid cancer, radiation exposure, and certain genetic syndromes. Symptoms of thyroid cancer can vary, but may include pain in the neck or throat, difficulty swallowing or breathing, and hoarseness. Treatment for thyroid cancer depends on the specific type and stage of the condition. Options may include surgery to remove all or part of the thyroid gland, radiation therapy, and medication to regulate thyroid hormone levels.
