What is brain cancer?
Brain cancer is an overgrowth of cells in your brain that forms masses called tumors.
Cancerous, or malignant, brain tumors can grow very quickly, depending on the type of tumor. They can disrupt the way your body works, and this can be life-threatening.
However, brain cancer is quite uncommon. According to estimates from the American Cancer Society, people have less than a 1 percent chance of developing a malignant brain tumor in their lifetime.
What are the symptoms of brain cancer?
The symptoms of brain cancer depend on the size and location of the tumor.
