The signs and symptoms of a brain tumor depend on the brain tumor's size and location. Symptoms also might depend on how fast the brain tumor is growing, which is also called the tumor grade. General signs and symptoms caused by brain tumors may include: Headache or pressure in the head that is worse in the morning.
A brain tumor is an abnormal growth or mass of cells in or around your brain. Together, spinal tumors and brain tumors are called central nervous system (CNS) tumors. Brain tumors can be malignant (cancerous) or benign (noncancerous). Some tumors grow quickly, while others are slow growing.
The cause of most brain and spinal cord tumors is not fully understood, and there are very few well-established risk factors. But researchers have found some of the changes that occur in normal brain cells that may lead them to form brain tumors.
Brain cancer can be life-threatening due to the changes it causes to the vital structures of the brain. Some examples of malignant tumors that originate in or near the brain include olfactory neuroblastoma , chondrosarcoma and medulloblastoma .
Brain cancer is an overgrowth of cells in your brain that forms masses called brain tumors. Learn more about the causes, symptoms, and treatment of brain cancer.
Small, benign brain tumors might not grow or might grow so slowly that they won't ever cause problems. You might have brain MRI scans a few times a year to check for brain tumor growth. If the brain tumor grows more quickly than expected or if you develop symptoms, you might need treatment.
The most common cancerous, or malignant, brain tumor is the glioblastoma, a type of glioma that begins in the brain or spinal cord. The most common primary noncancerous, or benign, brain tumor is the meningioma, which arises from the membranes that surround the brain and spinal cord.
The growing tumor puts pressure on your brain and can destroy otherwise healthy brain tissue, causing: Blurred or double vision. Headaches. Loss of appetite. Memory problems.
Glioblastoma is a type of cancer that starts as a growth of cells in the brain or spinal cord. It grows quickly and can invade and destroy healthy tissue. Glioblastoma forms from cells called astrocytes that support nerve cells. Glioblastoma can happen at any age.
Causes and Risk Factors. It's not usually clear what causes a brain tumor. "Most brain tumors arise spontaneously where a break occurs in a cell on its own," says Dr. Michael Brisman, a...
