Brain Tumour


No one knows what causes brain tumors. A brain tumor is also termed as intracranial neoplasm that occurs when abnormal cells form within the brain.

A tumor is a mass of tissue that’s formed by an accumulation of abnormal cells. Normally, the cells in your body age, die, and are replaced by new cells. With cancer and other tumors, something disrupts this cycle. Tumor cells grow, even though the body does not need them, and like normal old cells, they don’t die. As this process goes on, the tumor continues to grow as more and more cells are added to the mass. Primary brain tumors emerge from the various cells that make up the brain and central nervous system and are named for the kind of cell in which they first form. The most common types of adult brain tumors are gliomas and astrocytic tumors. These tumors form from astrocytes and other types of glial cells, which are cells that help, keep nerves healthy. The second most common type of adult brain tumors are meningeal tumors. These form in the meninges, the thin layer of tissue that covers the brain and spinal cord.


Signs and Symptoms of Brain Tumor

People with brain tumors often suffer from Headaches, seizures, sensory and motor loss, deep venous thrombosis, hearing loss, vision loss, fatigue, depression, behavioral and cognitive changes, endocrine dysfunction. These symptoms may be associated with the type, size, and/or location of the tumor, as well as the treatments used to manage it. Surgery, radiation, chemotherapy, and other treatments all have the potential to generate new symptoms as they work to reduce the impact of the tumor. Make an appointment with your doctor if you have persistent signs and symptoms that concern you.

How are brain tumors diagnosed?

If you have symptoms that suggest a brain tumor, your doctor will give you a physical exam and ask about your personal and family health history. You may have one or more of the following tests that includes Neurologic exam which means your doctor checks your vision, hearing, alertness, muscle strength, coordination, and reflexes. Your doctor also examines your eyes to look for swelling caused by a tumor pressing on the nerve that connects the eye and the brain. The second test is MRI that means a large machine with a strong magnet linked to a computer is used to make detailed pictures of areas inside your head. Doctor also suggests taking CT scan, which means an x-ray machine linked to a computer, takes a series of detailed pictures of your head. Another thing is Angiogram, where dye injected into the bloodstream makes blood vessels in the brain show up on an x-ray. The last test that affected person must take is Biopsy which is called the removal of tissue to look for tumor cells.
