A brain tumor is the presence of cancerous cells in the brain. There are 2 types of brain tumors.
Cancer occurs when cells in the body divide without control or order. Sometimes, cells divide uncontrollably when new cells are not needed. A mass of tissue called a growth or tumor forms. What causes these changes in the cells is unclear. It is likely to be a combination of gentic and environmental factors.
If the tumor does not invade other tissue it is considered a benign tumor. Although a benign brain tumor does not spread, it can cause damage by pressing on nearby brain tissue. Malignant tumors can invade nearby tissue and spread to other parts of the brain and spinal cord.
Factors that increase your child’s chance of a brain tumor include:
Symptoms depend on how large the tumor is and where it is located. A tumor can increase pressure in the skull and cause headaches. These headaches are different than the typical headaches that everyone gets. The headaches may:
A tumor can also affect the function of nearby tissue and cause:
You will be asked about your child’s symptoms and medical history. A physical exam will be done. Muscle strength, coordination, reflexes, response to stimuli, and alertness will be tested. Your child's eyes may be examined to check for signs of brain swelling.
Imaging tests will help evalute internal structures. This can be done with:
A biopsy of your child's brain tissue may be removed for testing. This will help identify certain characteristics of the tumor. If a tumor is present, results from a few different tests will be used to determine the stage. Staging is used determine a treatment plan.
Treatment depends on the type, size, and location of the tumor, and if it has spread. It also depends on your child’s overall health. Some treatments can affect nearby healthy tissue. This may lead to physical or mental limitations.
Medications can help control problems the tumor causes. Examples include:
Examples of surgical procedures used to treat brain tumors include:
Chemotherapy is the use of drugs to kill cancer cells. The drugs enter the bloodstream and travel through the body killing mostly cancer cells, but also some healthy cells. The drugs may be delivered into cerebrospinal fluid. This is fluid that surrounds the brain tissue.
Radiation therapy is the use of radiation to kill cancer cells or shrink tumors. This is a common treatment for brain tumors. Radiation therapy may be used alone or with chemotherapy. Radiation therapy may be:
Rehabilitation therapy is important to help regain lost skills or learn new ones. Rehabilitation therapy includes:
Your child may also work with an educational specialist. They can help with the transition back to school and with learning problems.
