Experimentally induced new abnormal growth of TISSUES in animals to provide models for studying human neoplasms.

Neoplasms composed of fibrous and epithelial tissue. The concept does not refer to neoplasms located in fibrous tissue or epithelium.

Neoplasms composed of fibrous tissue, the ordinary connective tissue of the body, made up largely of yellow or white fibers. The concept does not ref…

Neoplasms composed of primordial GERM CELLS of embryonic GONADS or of elements of the germ layers of the EMBRYO, MAMMALIAN. The concept does not refe…

Neoplasms composed of glandular tissue, an aggregation of epithelial cells that elaborate secretions, and of any type of epithelium itself. The conce…

Neoplasms composed of tissues of the OVARY or the TESTIS, not neoplasms located in the ovaries or testes. Gonadal tissues include GERM CELLS, cells f…

Certain tumors that 1, arise in organs that are normally dependent on specific hormones and 2, are stimulated or caused to regress by manipulation of…

Neoplasms composed of tissue of the mesothelium, the layer of flat cells, derived from the mesoderm, which lines the body cavity of the embryo. In th…

Two or more abnormal growths of tissue occurring simultaneously and presumed to be of separate origin. The neoplasms may be histologically the same o…

Neoplasms composed of muscle tissue: skeletal, cardiac, or smooth. The concept does not refer to neoplasms located in muscles.

Neoplasms composed of nerve tissue. This concept does not refer to neoplasms located in the nervous system or its component nerves.

Neoplasms composed of neuroepithelial cells, which have the capacity to differentiate into NEURONS, oligodendrocytes, and ASTROCYTES. The majority of…

Neoplasms associated with a proliferation of a single clone of PLASMA CELLS and characterized by the secretion of PARAPROTEINS.

Tumors, cancer or other neoplasms caused by or resulting from trauma or other non-radiation injuries.

Tumors, cancer or other neoplasms produced by exposure to ionizing or non-ionizing radiation.

Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different h…

Neoplasms of the SQUAMOUS EPITHELIAL CELLS. The concept does not refer to neoplasms located in tissue composed of squamous elements.

Metastases in which the tissue of origin is unknown.

Neoplasms composed of vascular tissue. This concept does not refer to neoplasms located in blood vessels.

Exfoliate neoplastic cells circulating in the blood and associated with metastasizing tumors.

The pathological mechanisms and forms taken by tissue during degeneration into a neoplasm and its subsequent activity.

The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the t…
