Is pilocytic astrocytoma a tumor of cerebellum?

Is pilocytic astrocytoma a tumor of cerebellum?

In theory anywhere: In theory, it could happen anywhere in the brain, but most juvenile pilocytic astrocytomas are in the supratentorial brain (outside of the posterior fossa). Posterior fossa tumors are typically ependymoma, medulloblastoma in kids. Jpa's don't happen in adults (adults get lgg's, or who ii low grade gliomas..Just almost never who i tumors). Most stem lesions are not jpa's, but they happen too. ...Read more

Astrocytoma (Definition)

Astrocytoma is a tumor that is arising from a specific cell type in the central nervous system (brain or spine) that is called astrocyte. These are the cells that support the actual nerve cells (neurons). It is a common type of nervous system tumor, which has different types, benign to malignant. Treatment is tailored according to this as well ...Read more

What percentage of ependymoma brain tumors are benign?

What percentage of ependymoma brain tumors are benign?

0%: All ependymoma brain tumors are technically malignant, meaning the cells are cancer and can grow into the surrounding brain tissue. However, most of these tumors (over 90%) are curable because the tumor is confined to one area, is slow-growing, and can be removed by surgery. Sometimes radiation alone is used for slow-growing brain ependymomas if surgery can't be performed. ...Read more

What percentage of diagnosed cancers are brain cancers?

What percentage of diagnosed cancers are brain cancers?

Small: In 2012 less than 3% of cancers were of the brain and nervous systems. In women, about 2% of cancer deaths were due to brain and other nervous system cancers. I hope this helps. Good luck. ...Read more

What are stages of squamous cell carcinoma?

What are stages of squamous cell carcinoma?

Differentiated: The pathology report will desribe well, moderate or poorly differentiated. Well differentiated is less advanced. It will also describe depth on invasion and whether nerves are involved. An evaluation of lymph nodes is done to confirm squamous cell is localized to skin. In advanced cases it will have spread requiring surgery followed by radiation, and possible chemotherapy. ...Read more

What is the progression rate of malignant brain tumors?

It depends: It depends on the tumor grade. Glioblastomas are most aggressive, and the median survival is about 2 years. Anaplastic astrocytomas progress more slowly, median survival is 4-5 years. New research is further subtyping these tumors. ...Read more

Describe the features of burkitt lymphoma?

Describe the features of burkitt lymphoma?

Very aggressive: One categorization of the many types of lymphoma is: indolent, aggresssive, very aggressive. Brukitt lymphoma (bl) is a very aggressive lymphoma. It proliferates (grows) very quickly. Intensive therapy is needed including intrathecal (cns fluid) chemotherapy. However, it usually responds quickly to treatment. That can cause rapid tumor death and tumor lysis syndrome (tls). ...Read more

What's the chromosome number of infiltrating ductal carcinoma?

Depends on grade: The level of chromosomal aberrations in infiltrating ductal carcinoma is correlated with the grade of the cancer cells. "grade" means the microscopic appearance and corresponds with how closely the cancer cells try to form normal breast structures. High grade or poorly differentiated infiltrating ductal carcinomas tend to have more chromosomal abnormalities than non-high grade carcinomas. ...Read more

What is the survival rate of patients with anaplastic astrocytoma?

3 years: The median survival for patients with a diagnosis of an anaplastic astrocytoma is 2.8 years (reference: journal of neurosurgery. 2007 apr;106(4):575-81.). The most important factor in determining the survival time period is the extent to which the tumor is removed surgically. ...Read more

Is anaplastic medulloblastoma a brain or childhood cancer?

Yes: Medulloblastoma (mb) is a brain cancer that occurs in the cerebellum, the back part of the brain. It occurs primarily in children, although it occasionally occurs in adults. They are classified by how they look under the microscope; anaplastic mb appears more aggressive under the microscope and is often more difficult to cure than other types of mb. ...Read more

Anaplastic glioma: Anaplastic astrocytoma is a tumor of the support cells of the brain. It is a malignant tumor in the midrange meaning it is not the most aggressive which is called a glioblastoma nor the most benign.
