    • (external-beam radiation therapy), or it may come from radioactive material
    • placed in the body near cancer cells (internal radiation therapy
  70. Rate of tumor growth
    • a measure, quantity, or frequency, typically one
    • measured against another quantity or measure
  71. Sinusoidal obstructive syndrome SOS

    • and hemorrhage
  72. Staging
    • Performing exams and tests to learn the extent
    • of the cancer within the body, especially whether the disease has spread from
    • the original site to other parts of the body. It is important to know the stage
    • of the disease in order to plan the best treatment
  73. TNM staging system
    • A system to describe the amount and spread of
    • cancer in a patient’s body, using TNM. T describes the size of the tumor and

    • lymph nodes; and M describes metastasis (spread of cancer to other parts of the
    • body
  74. Trismus
    • spasm of the jaw
    • muscles, causing the mouth to remain tightly closed, typically as a symptom of
    • tetanus
  75. Tumor

    • Refers to the number of cancer cells, the size of
    • a tumor, or the amount of cancer in the body. Also called tumor load.
  77. Tumor markers
    • A substance found in tissue, blood, or other
    • body fluids that may be a sign of cancer or certain benign (noncancerous)
    • conditions. Most tumor markers are made by both normal cells and cancer cells,
    • but they are made in larger amounts by cancer cells. A tumor marker may help to
    • diagnose cancer, plan treatment, or find out how well treatment is working or
    • if cancer has come back.
  78. Tumor necrosis factor-a (cachectin)
    • A protein made by white blood cells in response
    • to an antigen (substance that causes the immune system to make a specific
    • immune response) or infection. Tumor necrosis factor can also be made in the
    • laboratory. It may boost a person’s immune response, and also may cause
    • necrosis (cell death) of some types of tumor cells. Tumor necrosis factor is
    • being studied in the treatment of some types of cancer. It is a type of
    • cytokine. Also called TNF.
  79. Tumor suppressor genes
    • A type of gene that makes a protein called a
    • tumor suppressor protein that helps control cell growth. Mutations (changes in
    • DNA) in tumor suppressor genes may lead to cancer. Also called antioncogene.
