Headache:
Headache is a common symptom and most headaches do not mean that you have brain cancer or any other brain tumor. However, of people who do have a brain tumor, headache is a very common symptom.
Headaches caused by a brain tumor can vary in their character. Their location, frequency, and severity can all vary. However, many people with headaches caused by brain tumors say that the headache is worst in the morning or during the night and awakes them from sleep.
This is because the pain is typically due to pressure in the head. When we sleep, we normally hypoventilate, which means we breath slower and less deeply. This causes the blood vessels in the brain to dilate, letting more blood into the brain. If someone has a brain tumor, this additional blood in the brain can cause the pressure in the head to rise to point of causing pain, a headache. These headaches typically get better once the person is upright and awake.
Nausea and Vomiting:
Pressure on the brain from a brain tumor can irritate the centers in the brain stem that control the sense of nausea and the act of vomiting. Patients may complain of nausea or vomiting that do not seem to be initiated by other illness (such as a flu or food poisoning) and is not related to diet or meals.
Seizures:
While there are many different causes of seizures, they are one of the common symptoms of brain cancer. The tumor causes injury and irritation to parts of the brain that sets off uncontrollable rhythmic electrical activity in the brain, a seizure.
Not all seizures cause muscular convulsions, although this type of seizure is common. It is generally said that if an adult, who does not have a prior history of seizures, has a seizure for the first time, it is very likely that a brain tumor is to blame. Any person experience new seizures should be evaluated by a medical professional.
