  • Graft

    (graft)

    Healthy skin, bone, or other tissue taken from one part of the body and used to replace diseased or injured tissue removed from another part of the body.

  • Graft versus host disease

    The condition that results when the immune cells of a transplant (usually of bone marrow) from a donor attack the tissues of the person receiving the transplant. A reaction of engrafted tissue against your own tissue.

  • Graft-versus-tumor

    (graft-VER-sus-TOO-mer)

    An immune response to a person's tumor cells by immune cells present in a donor's transplanted tissue, such as bone marrow or peripheral blood.

  • Granual Cell Tumors

    (GRAN-yoo-lur sel TOO-mer)

    A rare type of soft tissue tumor that usually begins in Schwann cells (cells that hold nerve cells in place). It can occur anywhere in the body, but it usually occurs in or under the skin of the head and neck (especially the mouth or tongue). It may also occur in the chest, breast, esophagus, stomach, or other internal organ. Most granular cell tumors are benign (not cancer), but some may be malignant (cancer) and spread quickly to nearby tissue. They usually occur in middle-aged adults. Also called Abrikossoff tumor.

  • Granular cell tumor

    (GRAN-yoo-lur sel TOO-mer)

    A rare type of soft tissue tumor that usually begins in Schwann cells (cells that hold nerve cells in place). It can occur anywhere in the body, but it usually occurs in or under the skin of the head and neck (especially the mouth or tongue). It may also occur in the chest, breast, esophagus, stomach, or other internal organ. Most granular cell tumors are benign (not cancer), but some may be malignant (cancer) and spread quickly to nearby tissue. They usually occur in middle-aged adults. Also called Abrikossoff tumor.

  • Granulocytes

    A type of immune cell that has granules (small particles) with enzymes that are released during infections, allergic reactions, and asthma. Neutrophils, eosinophils, and basophils are granulocytes. A granulocyte is a type of white blood cell. Also called granular leukocyte, PMN, and polymorphonuclear leukocyte.

  • Grief

    (greef)

    The normal response to a major loss, such as the death of a loved one. Grief may also be felt by a person with a serious, long-term illness or with a terminal illness.

  • Groin

    (groyn)

  • Growth and development milestones

    (grothe ... dee-VEH-lup-MENT MILE-stones)

    Goals for the expected sizes of infants and children and activities they should be able to do at specific ages, such as sit, stand, play, speak, think, and interact with others.

  • Growth factors

    grothe FAK-ter

    A substance made by the body that functions to regulate cell division and cell survival. Some growth factors are also produced in the laboratory and used in biological therapy.
