Symptoms of brain tumors depend on the size of the tumour and it's position in the brain. The most common symptoms are headaches and seizures. Headaches are usually worse in the morning but wear off during the day. They are due to increased pressure in the skull. Although headaches are one of the most common symptoms of a brain tumor, remember headaches are common and most aren't caused by brain tumors. Other symptoms include: feeling sick, blurred vision, drowsiness, changes in personality, memory or mental ability, weakness on one side of the body, difficulties with speaking or hearing or with sense of smell. These symptoms aren't always due to a brain tumor, but if you have them, you should visit your doctor.
