Patients should talk with their doctor for more information about tumor grade and how it relates to their treatment and prognosis.
Cancer stage refers to the size and/or extent (reach) of the original (primary) tumor and whether or not cancer cells have spread in the body. Cancer stage is based on factors such as the location of the primary tumor tumor size, regional lymph node involvement (the spread of cancer to nearby lymph nodes ), and the number of tumors present.

A brain tumor, known as an intracranial tumor, is an abnormal mass of tissue in which cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. More than 150 different brain tumors have been documented, but the two main groups of brain tumors are termed primary and metastatic.
This report is important for you, the tumor registrar, because it may tell you which structures and organs of the body are involved by the tumor. It verifies the primary site of the cancer and describes the extent to which it has spread. Tumor size will usually be stated in the gross description of the surgical specimen.
Metastatic brain tumors (also called secondary brain tumors) are caused by cancer cells spreading (metastasizing) to the brain from a different part of the body. The cancer cells break away from the primary tumor and travel to the brain, usually through the bloodstream, then commonly go to the part of the brain called the cerebral hemispheres.

Tumors the first step in evaluating a potential oropharyngeal tumor is a comprehensive history and physical examin-ation. Typically, this is followed by panendoscopy with biopsies of suspicious areas. Particularly important points to elicit in taking a history include the presence/absence of trismus, dysphagia, odynophagia, altered tongue mobi-.
Sca1-positive cells from kras;p53-flox tumors were highly enriched for tumor-propagating activity. Sca1 status did not enrich for tpcs in kras tumors and only sca1-negative cells propagated egfr tumors. Thus, primary tumor genotype is an important determinant of the cell-surface phenotype of lung tumor-propagating cell populations.
