Thyroid cancer

Tumor - thyroid; Cancer - thyroid; Nodule - thyroid cancer; Papillary thyroid carcinoma; Medullary thyroid carcinoma; Anaplastic thyroid carcinoma; Follicular thyroid cancer

Thyroid cancer is a cancer that starts in the thyroid gland. The thyroid gland is located inside the front of your lower neck.

Endocrine glands

Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the pace of chemical activity in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

Thyroid cancer - CT scan

This CT scan of the upper chest (thorax) shows a malignant thyroid tumor (cancer). The dark area around the trachea (marked by the white U-shaped tip of the respiratory tube) is an area where normal tissue has been eroded and died (necrosis) as a result of tumor growth.

Thyroid cancer - CT scan

This CT scan shows a thyroid cancer tumor in the throat, encircling, narrowing, and displacing the windpipe (trachea).

Thyroid gland

The thyroid gland, a part of the endocrine (hormone) system, plays a major role in regulating the body's metabolism.

Incision for thyroid gland surgery

The thyroid is a gland located in the neck. It is a part of the endocrine (hormone) system, and plays a major role in regulating the body's metabolism. If surgery or an open excisional biopsy is needed, an incision is made in front of the neck to gain access to the thyroid gland.
