One of the best ways is with FDG-18 PET scans. This is because non-iodine avid disease is often metabolically super-active and concentrates the radioactive glucose rapidly. This then "lights up " on the PET scan.

Papillary, follicular, medullary and anaplastic
Papillary thyroid cancer is considered the most common form of thyroid cancer. According to ThyroidAwareness.com, papillary thyroid cancer is most commonly diagnosed in women 30-40 years old and it most frequently spreads to the neck lymph nodes.
Thyroid cancer is generally associated with very high survival rates. The prognosis for thyroid cancer is often favorable, with the majority of patients surviving the disease. Survival rates can vary depending on the specific type and stage of thyroid cancer. Here are some general survival rate statistics: Papillary Thyroid Cancer: Papillary thyroid cancer, the most common type, has a high survival rate. The 5-year relative survival rate for localized papillary thyroid cancer is approximately 99%, meaning that almost all patients with localized disease are alive 5 years after diagnosis. Even for regional (spread to nearby lymph nodes) or distant (metastatic) disease, the 5-year survival rate remains relatively high at around 93%. Follicular Thyroid Cancer: Follicular thyroid cancer also has favorable survival rates. The 5-year relative survival rate for localized disease is approximately 97%. For regional disease, it's about 86%, and for distant disease, it's around 67%. Medullary Thyroid Cancer: Medullary thyroid cancer has slightly lower survival rates compared to papillary and follicular types. For localized disease, the 5-year relative survival rate is around 98%. For regional disease, it's about 89%, and for distant disease, it drops to approximately 41%. Anaplastic Thyroid Cancer: Anaplastic thyroid cancer is the most aggressive form of thyroid cancer, and survival rates are much lower. The 5-year relative survival rate for this type is generally less than 10%, and many cases are fatal.
Anaplastic thyroid cancer usually arises from a site of preexisting papillary thyroid cancer or follicular thyroid cancer. The transformed cells that grow to form this type of cancer divide rapidly to form disorganized masses. Anaplastic thyroid cancer tends to grow very rapidly, replacing the normal tissue of the thyroid gland and spreading to invade and metastasize to other structures in the neck. It does not respond well to treatment. Surgery and external beam radiation therapy may be used to treat cases where aggressive growth of cancer has significantly impaired swallowing or breathing. On the whole, anaplastic thyroid cancer has a very poor prognosis.
If you have Hashimoto's thyroiditis, there are some links between the autoimmune condition and thyroid cancer. One study suggests that Hashimoto's does increase the risk. Meanwhile, another study showed that Hashimoto’s thyroiditis is commonly seen surrounding papillary thyroid cancer.

metastatic breast cancer
Radiation also is used in the treatment of patients with metastatic disease. It is particularly useful in shrinking metastatic colon cancer to the brain.
The most common types of thyroid cancer are Papillary and Follicular thyroid cancer, Medullary thyroid cancer and Anaplastic thyroid cancer. Depending upon a patient's age and diagnosis, there are different stages of thyroid cancer.For Papillary and Follicular thyroid cancer patients under 45, ThyCa (Thyroid Cancer Survivors' Association, Inc.) says there are two stages. For those over 45, ThyCa says there are four stages.For Medullary thyroid cancer, ThyCa says there are zero to four stages. Stage zero, they say, can only be found using a screener test; there is no tumor present.As for Anaplastic thyroid cancer, ThyCa says this cancer grows quickly; so stage four is divided into stages.
The thyroid is a butterfly shaped organ positioned in the front of the neck below the voice box. The thyroid gland produces important hormones that work toward the normal metabolism of the body. The follicular cells of the thyroid affect an individual's heart rate, energy level, and body temperature. C cells in the thyroid regulate the amount of calcium in the body. Thyroid cancer originates in the thyroid gland. Four types of thyroid cancer exist, which include papillary, medullary, follicular, and anaplastic.Types of Thyroid CancerThyroid cancer can begin in the follicular or C cells, depending on the type of thyroid cancer an individual develops. Majority of thyroid cancer patients are diagnosed with papillary or follicular thyroid cancer. Most individuals are successfully treated because most types of thyroid cancer are slow to grow and spread to other organs. Patients have the best chance of survival when the cancer stays in the thyroid. Medullary and anaplastic account for a very small percentage of thyroid cancer cases. Anaplastic is the most aggressive form of thyroid cancer.SymptomsEarly stages of thyroid cancer do not produce symptoms, but symptoms manifest as the cancer begins to grow. Common symptoms include a lump or mass in the front of the neck close to the Adam's apple, hoarseness or difficulty speaking, pain in the neck or throat, or swollen lymph nodes located in the neck. These symptoms can also be associated with an infection, a benign goiter or another issue associated with the thyroid.TreatmentsThe type of treatment recommended depends on the severity and specific type of thyroid cancer found in an individual. The most common type of treatment for thyroid cancer is surgery. The thyroid and any infected lymph nodes are removed during the surgery. A surgeon may recommend a lobectomy for certain patients, in which the lobe with the cancerous nodule is removed. Most patients must take thyroid hormone pills after having part or all of their thyroid removed.
