The three major symptoms of general brain tumors

Brain tumors are more life-threatening and more serious than tumors in other parts of the body, and have a greater impact on people's quality of life. So what are the early clinical symptoms of brain tumors?

1) Vomiting: It is 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.

2) Headache: It is caused by increased intracranial pressure or direct compression and stimulation of the meninges, blood vessels and nerves by the tumor. This is the most common early clinical symptom of brain tumors, which worsens as the tumor develops.

3) Visual impairment: including changes in vision, visual field and fundus. Due to increased intracranial pressure, optic disc edema occurs or the optic nerve is directly compressed by a tumor. Over time, the optic nerve can atrophy and affect vision, resulting in 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 ocular venous pressure, and causes venous congestion. In addition, there may be dizziness, diplopia, mental symptoms, epileptic seizures, stiff neck, decreased corneal reflex, and changes in vital signs such as breathing and blood pressure.

Because brain function is so important, the dangers of brain tumors can be imagined. Therefore, understanding the early clinical symptoms of brain tumors and early detection and treatment can help you grasp the best time to treat the disease.
