Types of Brain Cancer
Brain tumors are abnormal growths of cells in the brain.

– Although such growths are popularly called brain tumors, not all brain tumors are cancer. Cancer is a term reserved for malignant tumors.
– Malignant tumors can grow and spread aggressively, overpowering healthy cells by taking their space, blood, and nutrients. They can also spread to distant parts of the body. Like all cells of the body, tumor cells need blood and nutrients to survive.
– Tumors that do not invade nearby tissue or spread to distant areas are called benign.
– In general, a benign tumor is less serious than a malignant tumor. But a benign tumor can still cause many problems in the brain by pressing on nearby tissue.
In the U.S., brain or nervous system tumors affect about 6 of every 1,000 people.

Primary Brain Cancers
The brain is made up of many different types of cells.

– Some brain cancers occur when one type of cell transforms from its normal characteristics. Once transformed, the cells grow and multiply in abnormal ways.

– As these abnormal cells grow, they become a mass or tumor.

– The brain tumors that result are called primary brain tumors because they originate in the brain.
– The most common primary brain tumors are gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal tumors (medulloblastomas). The term glioma includes glioblastomas, astrocytomas, oligodendrogliomas, and ependymomas.

– Most of these are named after the part of the brain or the type of brain cell from which they arise.

    When you are diagnosed with brain cancer, learning as much as you can about it can help you decide on the best treatment for you.A brain tumor is a mass of cells in your brain that are not normal. There are two general groups of brain tumors, primary brain tumors start in brain tissue and tend to stay there, whereas secondary brain tumors are more common and start somewhere else in the body and travel to the brain such as lung, breast, kidney, colon, and skin.

    By experts opinion that Astrocytomas; these usually arise in the largest part of the brain, the cerebrum. They can be any grade. Meningiomas; these are the most common primary brain tumors in adults. Oligodendrogliomas; these arise in the cells that make the covering that protects nerves. Thank you so much for this posting. Love it.
