The symptoms of patients with early brain cancer are extremely subtle

If brain cancer is treated late, its prognosis is relatively poor. Brain cancer is one of the most common diseases. How much do you know about the early symptoms of brain cancer? Below, experts will introduce the early symptoms of brain cancer .

1. Common symptoms

—) Headache: It is caused by increased intracranial pressure or direct compression and traction of the meninges, blood vessels and nerves by the tumor. It occurs in most patients and is an early symptom of brain cancer, which worsens as the tumor develops to the late stage.

2) Vomiting: Early symptoms of brain cancer are mostly caused by increased intracranial pressure stimulating the medullary vomiting center and vagus nerve stimulation. Severe headaches are accompanied by vomiting, which is often jet-like. Children with posterior cranial fossa tumors will have vomiting early and frequently, which can be easily mistaken for gastrointestinal diseases.

3) Visual impairment: including changes in vision, visual field and fundus. Due to increased intracranial pressure, optic disc edema occurs or the tumor directly compresses the optic nerve. Over time, it can cause optic nerve atrophy and affect vision, causing vision loss or even blindness. The cause of optic disc edema is increased intracranial pressure, which restricts the return of lymph in the lymphatic sheath around the optic nerve, increases the pressure of the ocular veins, and causes venous congestion. In addition, there may be dizziness, diplopia, mental symptoms, epileptic seizures, neck stiffness, decreased corneal reflexes, and changes in vital signs such as breathing and blood pressure. These are the early symptoms of brain cancer.

2. Local symptoms

Local symptoms are also called localization symptoms. Due to the differences in the location of gliomas, the local symptoms they produce are also different. The location of the tumor can be determined clinically based on its manifestations and combined with other factors. Among them, the most important lesion symptoms, that is, the result of direct compression, stimulation or destruction of brain tissue or cranial nerves by the tumor, have localization value. However, the symptoms that appear in the early stage of the disease are most diagnostically significant.

After reading the above brief introduction to the early symptoms of brain cancer, I hope it will be helpful to everyone. Everyone should pay more attention to the early symptoms of brain cancer, learn more about them, pay more attention to prevention in life, and treat them as soon as possible once they are discovered.
