    en.wikipedia.org/wiki/Neoplasm

    A neoplasm (/ ˈ n iː oʊ p l æ z əm, ˈ n iː ə-/) [1] [2] is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia . The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger ...

  4. Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions (there are also surgical and radiation oncologists).

  5. Endolymphatic sac tumor - Wikipedia

    en.wikipedia.org/wiki/Endolymphatic_sac_tumor

    Based on the anatomic site, it is difficult to completely remove, and so while there is a good prognosis, recurrences or persistence may be seen. There is no metastatic potential. Patients who succumb to the disease, usually do so because of other tumors within the von Hippel-Lindau complex rather than from this tumor.

  6. Gastrointestinal stromal tumor - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_stromal_tumor

    Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GISTs arise in the smooth muscle pacemaker interstitial cell of Cajal, or similar cells. [2] They are defined as tumors whose behavior is driven by mutations in the KIT gene (85%), [2] PDGFRA gene (10%), [2] or BRAF kinase (rare).

  7. Primary tumor - Wikipedia

    en.wikipedia.org/wiki/Primary_tumor

    A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass. Most solid cancers develop at their primary site but may then go on to metastasize or spread to other parts of the body. These further tumors are secondary tumors.

  8. Meningioma - Wikipedia

    en.wikipedia.org/wiki/Meningioma

    Even if, by general rule, neoplasms of the nervous system (brain tumors) cannot metastasize into the body because of the blood–brain barrier, anaplastic meningioma can. Although they are inside the cerebral cavity, they are located on the bloodside of the BBB, because meningiomas tend to be connected to blood vessels.

  9. Benign tumor - Wikipedia

    en.wikipedia.org/wiki/Benign_tumor

    A benign tumor is a mass of cells that does not invade neighboring tissue or metastasize (spread throughout the body). Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate.
