Brain Tumor - Types

Types

Tumors can be benign or malignant, can occur in different parts of the brain, and may or may not be primary tumors. A primary tumor is one that has started in the brain, as opposed to a metastatic tumor, which is something that has spread to the brain from another part of the body. Tumors may or may not be symptomatic: some tumors are discovered because the patient has symptoms, others show up incidentally on an imaging scan, or at an autopsy.

The most common primary brain tumors are:

  • Gliomas (50.4%)
  • Meningiomas (20.8%)
  • Pituitary adenomas (15%)
  • Nerve sheath tumors (8%)

Famous quotes containing the word types:

    Our major universities are now stuck with an army of pedestrian, toadying careerists, Fifties types who wave around Sixties banners to conceal their record of ruthless, beaverlike tunneling to the top.
    Camille Paglia (b. 1947)

    The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.
    Henry Brooks Adams (1838–1918)

    The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.
    Anton Pavlovich Chekhov (1860–1904)
