A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain.
Brain tumors can cause many symptoms. Some of the most common are
Doctors diagnose brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. Many people get a combination of treatments.

Brain cancer can run in families. Both behavioral and biological factors impact one’s risk. Inherited genes cannot be controlled. However, one can control their behavior and may decrease their risk this way. Smoking, alcohol consumption, chemical exposure, and radiation exposure should all be avoided to decrease one’s risk.
