Cancers that form from brain tissue are called primary brain tumors. Brain tumors may be malignant (brain cancer) or benign. Certain risk factors, such as working in an oil refinery, as a chemist, or embalmer, increase the likelihood of developing brain cancer. Symptoms include:
- difficulty walking,
- blurry vision,
- vomiting, and
- changes in speech, memory, or personality.
