Symptoms of a brain tumor - incorrectly referred to as brain cancer - appear after the formation of the so-called intracranial tightness. A tumor that grows in a closed space such as the cranial cavity causes an increase in pressure within it. The result is swelling of the brain, most often manifested by headache. However, this is not the only symptom of a developing cancer. Find out about the symptoms of a brain tumor.

The symptoms of a brain tumor- erroneously referred to asbrain cancer- vary depending on the degree of malignancy of the brain tumor and on which part of the brain is oppressive. Certain parts of the brain control various activities of the body. All brain tumors produce two types of symptoms: general and focal (local). They may show up immediately after the appearance of the tumor or even years later.
Symptoms of a brain tumor
The symptoms of a brain tumorare the result of an increase in intracranial pressure caused by tumor growth. The skull cavity is made of bones and therefore does not stretch. Therefore, an increase in the volume of the brain leads to an increase in intracranial pressure and the appearance of cerebral edema. Then the general symptoms of the brain tumor appear, as well as local symptoms, depending on the tumor location.
General symptoms of the brain tumor
- headaches that become more frequent and intense over time
- nausea and vomiting that occurs most often in the morning
- sleepiness
- bradycardia, i.e. too slow or irregular heart rate (children may develop tension and ripple of the crown of the head)
- loss of consciousness
- coma
Focal (local) symptoms of the brain tumordiffer depending on the location of the tumor:
- frontal lobe - personality change, behavioral disturbances, apathy or aggression, confusion, speech difficulties;
- temporal lobe - epileptic seizures associated with the perception of unpleasant odors. Inability to interpret various sounds (e.g. a dog barking);
- parietal lobe - speech disorders, using inadequate words, forgetting the names of objects or difficulties in understanding speech;reading and writing problems;
- occipital lobe - deterioration or loss of vision on one side;
- brainstem - facial asymmetry, choking, and even swallowing disorders (this is the result of paralysis of the nerves responsible for the functioning of the muscles in this area of the body);
- hypothalamic-pituitary axis - disturbances in the secretion of hormones that stimulate the reproductive system (in women, they can lead to a h alt of menstruation, among others);
- pathways of cerebrospinal fluid circulation - hydrocephalus;
- posterior-lower part of the brain (cerebellum) - balance disorders, difficulty in standing and inability to perform precise movements, e.g. holding a pen and writing efficiently.
