Types of brain tumors

presto class of categorizing of brain tumors is based onward whether they are benign or malignant in nature. Benign brain tumors do not consist of cancer cells and do not metastasize. The malignant brain tumors are composed of cancer cells. They are not limited to the tissue of origin and spread quickly to the neighboring tissues and metastasize.

Brain tumors could also be classified by cause of primary and secondary tumors. The primary tumors are the indicated that originate within the cells of the brain. They could be cancerous or non cancerous. Secondary tumours are the metastasized cells having spread from several other disconnect of the density to the brain and are obviously cancerous.

Causes of a brain tumor

Exact and diagnostic causes of brain tumors are at rest not known and their reasons remain ambiguous. It is quite clear though that it is at no time contagious and a person cannot “catch it” from some one having a tumor.

however the exact will still eludes us, there are believing risk factors that increase the chances of one developing the tumor. Gender is a dominant risk factor. They are predominantly detected in males. Age too is a risk factor. Majority of the cases show tumor developing in people at the age of 60 and above. Also, children below the age of 8 years are added prone to develop it. additional risk factors include family history and exposure to radiations.

abnormally it develops due to the abnormalities in genes that regulate the cell development cycle resulting in uncontrolled and abnormal division and growth of cells. These abnormalities in the genes could be due to some rearrangements in the chromosome or due to direct alterations in the genes. These abnormalities are a result of cascade of events taking place at molecular and balance biological levels.

certain genetic conditions like neurofibromatosis, Li-Fraumeni syndrome, retinoblastoma, etc. could augment the chances of developing tumors in the central nervous system. Genetic abnormalities causing brain tumors are rarely inherited. They are caused mainly due to differing environmental factors and in addition to due to various factors that could affect the genetic materials (like DNA) of the cells. heaps chemicals are existing time that could alter the genes involved in restraining the growth of tumors. Workers working in rubber manufacturing factories, oil refineries or as chemists are precariously exposed to specific chemicals.

also the patients who have been exposed to some kind of radiations in the olden by reason of treating several other malignancies are also capable of developing this condition.

Diagnosis and Treatment

They are generally diagnosed as a result of of manifestation of believing symptoms and analysis of the neurological functions. The patient is initially tested in a neurological exam testing all the absolute senses, balance, coordination and memory. Magnetic Resonance Imaging (MRI) is the prevalent technology used to diagnose a brain tumor. They are generally treated upon and efforts are put to reduce them to the maximum extent by surgery, radiotherapy (radiation treatment) or chemotherapy. These treatments are occasionally applied in combination’s to produce better effect.
