What is the connection between brain lesions and cancer?
The synchronized relationship exists between brain lesions and cancer elsewhere in the body. Medical studies have shown that cancer cells in prostate, breasts and lungs can often lead to concurrent brain drugs due to hematogenic spread of malignant cells. Lees can begin to metastasize in the brain within one to two months of the initial onset of primary cancer; Lung and breast cancer usually probably cause legions than prostate cancer, which usually does not reach the brain until late period. Cerebral lesions often occur in multiples, with most patients on average five lesions. Many surgeons believe that control of these lesions is the key to prolonging life expectancy in patients suffering from various cancer.
Several treatment procedures can be effective for brain lesions. Lees are most often removed by radiosurgery of gamma knife. Chemotherapy, excision and radiation are alternative options for both brain lesions and cancer depending on the number and size of lesions. A combination of two treatmentscould be consistently used for two to four -week periods for aggressive lesions of brain and cancer, especially if there is a history of recurrence.
Once the initial lesions are removed, 15 percent of patients may appear in new locations. Recurrent lesions in the same place often occur in up to 30 percent of patients, which reduces the survival rate. According to medical surveys of suffered patients, the survival of most people with brain lesions and cancer, which cannot be successfully removed by averages one year after diagnosis. This rate depends on how robust the extracranial cancer is and to what extent it responded to treatment.
Magnetic resonance imaging (MRI) and computer tomography (CT) are typical means through which patients discover have brain lesions. Sometimes it occurs by accident when the tests are performed for other diseases. Sometimes seizures, headaches,Learning and memory loss may indicate the presence of brain lesions. The relationship between the lesions of brain and cancer may not occur at the same time; Some patients do not develop brain lesions up to several years after they believe they were in the remission of cancer elsewhere in the body.
Not all cases of abnormal tissue in the brain indicate the dreaded lesions of the brain and binding to cancer. Some brain lesions are harmless or the result of past infections and physical injuries. Strokes, encephalitis, aneurysm and hydrocephalus can also lead to brain lesions. Patients with human immunodeficiency virus (HIV) suffering from brain lesions may or may not have cancer; Studies are in conflict about whether the legions in patients with acquired immune deficiency syndrome (AIDS) or HIV are parasitic infections or a rare form of cancer.
