Symptoms and Complications
Brain cancer causes symptoms when it pushes on the brain or destroys brain tissue. Symptoms depend on the size and location of the tumor as well as how quickly it grows. Although headaches are often a symptom of brain cancer, it is important to remember that most headaches are due to less serious conditions such as migraine or tension, not cancer. Headaches caused by a brain tumor are often severe, associated with nausea and vomiting and are usually worse in the morning. They can last for extended periods of time or may "come and go."
Other symptoms include:
-
dizziness
-
vision changes (such as double vision)
-
coordination problems
-
weakness or numbness on one side of the body
-
seizures
-
changes in mood, senses, personality, or feelings
-
memory problems
-
confusion or trouble concentrating
