The manifestations of a brain tumor are not very clear, so specific tests are always required to diagnose it. It is a serious health problem that requires immediate action.
A brain tumor is an abnormal growth of cells in the brain tissue. They can be benign, that is, non-cancerous, or malignant, having in their constitution cells of rapid and expansive growth with the possibility of metastasis.
Likewise, they are divided into primary, when they originate in the brain and the neurons found there, and metastatic, if they begin in another part of the body, but reach the brain through metastatic migration.
When the tumor is cancerous, it has a reserved and serious prognosis. It requires specific and meticulous treatments carried out by a medical team that has experience in these approaches. The recovery rate varies depending on the stage of development of the tumor, where it is located, and the general health of the patient.
Possible causes
The reasons for primary brain tumors are unknown. They are known to be preceded by a mutation in DNA that leads abnormal cells to divide uncontrollably and multiply without limit, simultaneously suppressing healthy cells.
What can be mentioned are risk factors, that is, situations or characteristics that are associated with a greater risk of suffering from it. Here we have genetics, heavy metals that poison the nervous system, radiation and diseases such as epilepsy.
In the case of metastatic tumors, the cause is a cancer located elsewhere in the body that migrates cells to the brain. This occurs even if the person is being treated for the original condition.
People who have had colon, breast, lung, or melanoma cancer are the most likely to develop secondary brain tumors. A little because of the way in which these oncological situations evolve, and the same because of the network of vascular and lymphatic vessels that carry circulation between the different tissues.
While there is no sure way to prevent a brain tumor, there is evidence that controlling radiation and environmental toxins reduces the risk. This is key in places where the presence of these agents is high, such as cities, clinics or areas with high voltage power lines.
