The thyroid ultrasound is also very effective to discover microcarcinomas, which refer to very small carcinomas (<1 cm). Papillary thyroid carcinomas are also discovered when a hard nodule is found in multinodular goiter, when enlarged cervical lymph nodes are detected, or when there are unidentified metastatic lesions elsewhere in the body.

Treatment of a thyroid nodule depends on many things including size of the nodule, age of the patient, the type of thyroid cancer, and whether or not it has spread to other tissues in the body. If the nodule is benign, patients may receive thyroxine therapy to suppress thyroid-stimulating hormone and should be reevaluated in six months. [2]
Histopathology of NIFTP, H&E stain. [1]Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is an indolent thyroid tumor that was previously classified as an encapsulated follicular variant of papillary thyroid carcinoma, [2] necessitating a new classification as it was recognized that encapsulated tumors without invasion have an indolent behavior, [2] and may ...
In medicine, nodules are small firm lumps, usually greater than 1 cm in diameter. [ 1 ] [ 2 ] If filled with fluid they are referred to as cysts . [ 2 ] Smaller (less than 0.5 cm) raised soft tissue bumps may be termed papules .
Medullary thyroid cancer is a form of thyroid carcinoma which originates from the parafollicular cells (C cells), which produce the hormone calcitonin. [1] Medullary tumors are the third most common of all thyroid cancers and together make up about 3% of all thyroid cancer cases. [2] MTC was first characterized in 1959. [3]
Thyroid function tests will help reveal whether the nodule produces excess thyroid hormones. A radioactive iodine uptake test can help reveal the activity and location of the cancer and metastases. [67] [69] Thyroid cancers are treated by removing the whole or part of thyroid gland. Radioactive Iodine-131 may be given to radioablate the thyroid.
