Brain Tumor

Brain tumors are the growth of abnormal cells in the brain. Many tumor types are different. Some brain tumors are not cancerous (benign) and several other brain tumors are cancerous (malignant). Brain tumors may originate in the brain (primary brain tumor) or cancer that originates in another part of the body and spread to the brain (brain tumors secondary / metastatic).


Signs and symptoms of common brain tumors can be:

• Appears headache or headache pattern changes
• Headache is gradually becoming more frequent and more severe
• Nausea or vomiting for no reason
• Problems with vision, such as blurred vision, etc.
• Gradually lost sensation or movement of an arm or leg
• Difficulty maintaining balance
• It is difficult to speak
• Confusion of everyday problems
• Changes in personality or habits
• Seizures, especially in someone who has never experienced seizures
• Hearing Problems

Causes & Risk Factors


Primary brain tumors

Primary brain tumors may originate in the brain itself or the tissue that covers the brain, such as the membrane of the meninges, cranial nerves, pituitary gland or pineal gland. Primary brain tumors begin when normal cells undergo a mutation in its DNA. This mutation causes the cells to grow in an uncontrolled and alive when other cells die.

There are several types of primary brain tumors. Each is named after a terkain cells. Among others:
• Acoustic neuroma (schwannoma)
• astrocytoma, also known as glioma, which consists of anaplastic astrocytoma and glioblastoma
• ependymoma
• Ependymoblastoma
• Germ cell tumors
• Medulloblastoma
• Meningioma
• Neuroblastoma
• oligodendroglioma
• Pineoblastoma

Secondary brain tumors / metastatic

Secondary brain tumors / metastatic tumors are generated 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 tumors 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

Risk factors for brain tumors include:
• Race. Brain tumors occur most often in people who were white, except meningioma.
• Age. Brain tumor risk increases with age.
• Exposure to radiation. Examples of radiation for cancer treatment.
• Exposure to chemicals at work.
• Records of families with brain tumors.
