Brain Tumor

Brain tumor is a mass or growth of abnormal cells in your brain. Many different types of brain tumors exist. Some brain tumors are benign, and some brain tumors are malignant.

Brain tumors can begin in your brain and, other cancer can start in other parts of your body. Brain tumors can affect the function and press the surrounding nerves, tissue, and blood vessel.

Symptoms of Brain Tumor

Onset or change in the pattern of headaches
Headaches that gradually become more frequent and more severe
Vision problems
Unexplained nausea or vomiting
Difficulty in balancing
Speech difficulties
Tiredness
Confusion
Trouble in making decisions
Gradual loss of sensation or movement in an arm or a leg
Inability to follow simple rules
Personality or behavior changes
Seizures and hearing problems

Brain tumor headaches are adverse to typical migraines. Brain tumor-related headaches are persistent and lead to sharp and stabbing pain.

Types of Brain Tumors

Gliomas. The tumors start in the glial cells and are often cancerous. Glioblastoma is the most aggressive type of glial tumor.
Meningiomas. It forms in the thin layer of tissue that covers the brain and spinal cord. Meningiomas are not cancerous but, it causes problems by pressing on your brain.
Schwannomas. It damages the protective coating of nerve cells. They are benign but may lead to hearing loss and problems in balancing.
Pituitary adenomas. It sits at the base of your brain and, they are slow-growing. These are benign types of tumors.

Causes and Risk Factors of Brain Tumor

Family history and age
Race
Chemical exposure
Exposure to radiation
No history of chickenpox

Stages of Brain Tumor

Tumor histology includes finding out the type of tumor and grade. For most tumors, the lower the grade level, the better the prognosis. Stages/Grade of brain tumor:

Grade 1. It is noncancerous and resembles healthy cells in appearance. It is often treatable with surgery.

Grade 2. The tumors are malignant but slow-growing. These tumors can spread to adjacent tissues or recur after initial therapy.

Grade 3. It is malignant and develops more quickly than grade 1 and 2 tumors. Under the microscope, the malignant cells display severe abnormalities. It can generate abnormal cells that can spread to areas of the brain.

Grade 4. The brain tumors develop rapidly and have various abnormal features under a microscope. The timeline of the growth of the cancer cell is aggressive.

How to Diagnose Brain Tumor?

Diagnosis of a brain tumor begins with a physical exam and a look at your medical history.
CT scan of the head
MRI of the head
Angiography
Skull X-rays
Biopsy
