What factors affect the brain tumor prognosis?

Patients diagnosed with brain tumor may have a very changing life expectations. A number of factors are important in determining the patient's prognosis. First, the type of cancer present is very important because different types of malignant growth have different degrees of aggression. The size and location of the tumor at the time of diagnosis is also important. Another relevant factor in the cerebral tumor prognosis is whether the primary tumor metastasized or spread to the body far from the brain.

One of the important factors that affects the brain tumor prognosis is the type of tumor present. Many different cells placed in the brain can develop into cancer growth and the resulting tumors have different capabilities to increase size and spread to other areas of the body. For example, one type of brain tumor called glioblastoma multiform (GBM) is very aggressive and patients with diagnosing this tumor usually survive for less than a year. Meningioma, on the other hand, a tumor derived from the membranes lining the brain, grows much slower and is lesslikely to metastasize to other areas of the body. Patients who receive this diagnosis of cancer have a longer life expectancy.

Another important aspect of brain tumor prognosis is the tumor size at the time of diagnosis. In general, tumors that are larger have a worse prognosis than tumors that are smaller. This is because these larger tumors had more time to grow, spread and involve into important brain structures. Large tumors located in the brain may be particularly dangerous because there is a limited space in the skull. Excessive tumor growth could cause herniation - or move - brain outside Leb, which could lead to loss of consciousness and stop breathing.

Unlike many other types of tumors that affect different organs in the body, the location of the brain tumor can significantly affect the patient's prognosis. The reason is the fact that the regions of the brain are highly specialized in their skillscheck aspects of body operation. The brain tumor affecting the brain stem could be fatal because this area of ​​the brain controls vital processes such as breathing, beating heart and circulation of blood. One placed in the frontal lobe of the brain can only cause personality changes and may not be an instantly threatening life.

Whether the tumor metastasis also affects the prognosis of the brain of the tumor. Cancer cells can spread from the brain to other areas of the body through the lymphatic system or blood. Although brain tumors are metastasized as often as some other tumors in the body, if spreading to distant areas, the patient's prognosis is relatively poor. It is worth mentioning, other tumors such as lung cancer, cancer or colon cancer often metastasizes into the brain area. Generally, brain metastases are a poor prognostic sign for patients with these other cancers.
