Symptoms of vomiting in advanced brain cancer

When it comes to common diseases, I believe everyone will tend to prefer the diseases they are more familiar with. However, when it comes to brain diseases, everyone may think of brain cancer first, because it is a cancerous disease with a very high incidence rate. Brain cancer is a very harmful disease. For patients, the onset of brain cancer may even be a disease that threatens the patient's life safety. Pay attention to the symptoms of brain cancer to grasp its treatment opportunity. In the late stage of brain cancer, does vomiting and other symptoms occur? The following is a detailed introduction.

The main symptoms of advanced brain cancer are as follows:
1. Epileptic seizures: These are most common in frontal lobe tumors and can manifest as systemic seizures or localized minor seizures, sometimes with premonitory symptoms such as hallucinations and vertigo. Parietal lobe tumors may cause abnormal sensations such as limb numbness before an epileptic seizure, which is one of the symptoms of advanced brain cancer.
2. Vomiting: It is mostly caused by increased intracranial pressure stimulating the vomiting center in the medulla oblongata and traction stimulation of the vagus nerve. The vomiting is characterized by jet-like shape. Children with posterior cranial fossa tumors will experience vomiting early and frequently, and it is often misdiagnosed as an intestinal disease.
3. Visual impairment: Visual impairment includes changes in vision, visual field and fundus, which are caused by increased intracranial pressure resulting in optic disc edema or direct compression of the optic nerve by a tumor. Over time, both can cause optic nerve atrophy and affect vision, resulting in vision loss or even blindness.
