In brain tumors, many cells in the brain or one cell grows abnormally. Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some brain tumors are cancerous (malignant). Brain tumors can begin in your brain (primary brain tumors), or cancer can begin in other parts of your body and spread to your brain (secondary, or metastatic, brain tumors). The biggest problem with this is that there are no specific reasons for this, only some researchers have detected some of its risk factors.
How quickly a brain tumor grows can vary greatly. The growth rate as well as location of a brain tumor determines how it will affect the function of your nervous system. The signs and symptoms of a brain tumor vary greatly and depend on the brain tumor’s size, location and rate of growth. General signs and symptoms caused by brain tumors may include:
Personal and behavioral changes: Those who have tumors in the frontal lobe are unable to control their behavior. They have difficulty in learning new things.
Trouble speaking: If someone has a tumor in the temporal lobe, there is difficulty in speaking, it is not spoken properly.
Trouble in balancing the body: When someone has a tumor, the balance of his body is not able to be made, because if there is a tumor in the cerebellum then it affects the movement.
Headache: This is the biggest symptom of brain tumor. This pain mainly occurs in the morning and later it starts happening continuously, this pain intensifies. If such a symptom appears, get it checked.
Disturbances in daily activities: Sensation is affected when there is a tumor in the parietal lobe, due to which the person has difficulty in daily activities.
Feeling of boredom or vomiting: Like a headache, it also occurs in the morning, especially when a person moves from one place to another.
Seizures: Brain tumors can push on nerve cells in the brain. This can interfere with electrical signals and result in a seizure. A seizure is sometimes the first sign of a brain tumor, but it can happen at any stage. About 50 percent of people with brain tumors experience at least one seizure.
