Brain tumor is a growth of abnormal cells in the brain. Many types of different tumors. Some brain tumors are not cancerous (benign) and several other brain tumors are cancerous (malignant). Brain tumors may originate from the brain (primary brain tumors) or cancer originating from other parts of the body and spread to the brain (brain tumors secondary / metastatic).
Symptom
Signs and symptoms of brain tumor can be either:
• Appears headache or changes in the pattern of headaches
• Headache gradually become more frequent and more severe
• Nausea or vomiting for no reason

Causes & Risk Factors
cause
Primary brain tumors
Primary brain tumors can originate in the brain itself or tissues that cover the brain, such as the membrane of the meninges, cranial nerves, pituitary gland or the pineal gland. Primary brain tumors begin when normal cells have mutations in their DNA. This mutation causes the cells to grow uncontrollably and stay alive while other cells die.
There are several types of primary brain tumors. Each is named after terkain cells. Among others:
• Acoustic neuroma (schwannoma)
• Astrocytoma, also known as gliomas, which is composed of anaplastic astrocytoma and glioblastoma
• Ependymoma
• Ependymoblastoma
• Germ cell tumors
• Medulloblastoma
• Meningioma
• Neuroblastoma
• oligodendroglioma
• Pineoblastoma
Secondary brain tumors / metastatic
Secondary brain tumors / metastatic tumors resulting from cancer originating from other parts of the body and then spread to the brain. Secondary brain tumors most often occur in people who have a record with cancer. But it can also occur, although rarely, metastatic brain tumor is an early sign of cancer that starts from the other body parts.
Any cancer can spread to the brain, but the most common types include:
• Breast cancer
• Colon cancer
• Kidney Cancer
• Lung cancer
• Melanoma
risk factors
Brain tumor risk factors, among others:
• Race. Brain tumors occur most often in people who were white, except meningioma.
• Age. The risk of brain tumors increases with age.
• Exposure to radiation. Examples of radiation for cancer treatment.
• Exposure to chemicals at work.
• Note families with a brain tumor.
