What are the complications associated with a brain tumor?

Some people with a brain tumor — whether it is benign or malignant — experience complications as the tumor grows and presses on surrounding tissue. These complications include:

• Decreased alertness.
• Difficulty speaking.
• Faster or slower breathing and pulse rates.
• Numbness that interferes with feeling pressure, heat or cold on the body.
• Weakness or inability to move a leg or arm on one side of the body.
• Vision, hearing and smelling problems.
