Areas of abnormal tissue that may or may not be cancerous.

A machine that uses electricity to form a stream of fast-moving subatomic particles. This creates high-energy radiation that may be used to treat cancer.

A localized tumor is contained in one area of the body.

Tests that look at how well the lungs work, such as by measuring how much air a person can exhale after taking in a deep breath. Also called pulmonary function tests.

Lung neuroendocrine tumors – an uncommon form of lung cancer caused by NETs. There are two grades (grade 1 and grade 2) of lung NETs depending on how quickly they grow.

A substance that emits radiation (radionuclide) and is one of most commonly used radionuclides for peptide receptor radionuclide therapy (PRRT) in treating NETs.

A method of obtaining a thin cross-sectional X-ray view of a patient, using a large electromagnet to cause atoms in the body to emit radio waves. It is one of the main imaging techniques used for diagnosing and monitoring NETs.

Malignant tumors are made up of cells that grow out of control. Cells in these tumors can invade nearby tissues and spread to other parts of the body.

A NET found in the thyroid gland.

The by-product of a biochemical reaction within the body.

A process that describes how cancer cells spread from one part of the body to another.

To spread from one part of the body to another. The words “localized,” “regional,” and “distant,” are sometimes used to describe how much a NET has spread, or metastasized.

An imaging test that uses the radiopharmaceutical metaiodobenzylguanidine (MIBG) to help locate and diagnose certain types of cancer in the body.

A group of two or more atoms linked together by sharing electrons in a chemical bond. Molecules are the fundamental components of chemical compounds and are the smallest part of a compound that can participate in a chemical reaction.

A membrane rich in mucous glands. The gastrointestinal mucosa lines the stomach and intestines, supplying support, protection, and nutrients.

Healthcare professionals from various clinical areas who can help to advise patients about the different aspects of their NETs care.

A rare, genetic condition that causes tumors to develop in endocrine glands, most commonly in the parathyroid glands, pituitary gland and the pancreas. People with MEN 1 have a high risk of developing NETs.

A term that is used when examinations and tests can find no cancer in a person who has been treated for cancer, be it blood work and or scans. (NED) does not mean that the disease has been cured, since recurrence can not be entirely ruled out or predicted when recurrence will take place in the future.
