In cancer, the stage denotes the extent of the disease, especially whether it has spread from the original site to other parts of the body.
Staging cancer
A standardized way to classify a tumor based on its size, whether it has spread, and where it has spread; staging measures the extent of the disease.

Multiple beams of high-dose radiation focused on a specified location in the body. The technique enables the radiation oncologist to kill cancer cells and limit the exposure of healthy tissue to radiation.
A kind of framework, made up of connective tissue, that provides support, structure, and anchoring for organs.
Under the skin.
Sunitinib malate (Sutent)
One of the approved chemotherapy drugs for pancreatic neuroendocrine tumors, it is a tyrosine kinase inhibitor with potential anticancer activity.

Superior mesenteric vein
The blood vessel that drains the small intestine. Its endpoint is behind the head of the pancreas.
A product that is added to the diet, such as a vitamin, mineral, or herb.

Treatment designed to kill only cancer cells and not healthy cells.
The treatment of disease.
Three-dimensional conformal radiation therapy (3D-CRT)
Treatment with radiation that uses beams matched to the shape of the tumor.
TNM system
A system used to evaluate cancer; T stands for tumor, N for node, and M for metastasis.
