Will you feel like vomiting if you have brain cancer?

Brain tumor is a disease that has had a great impact on human beings so far. Many people suffer from it and are in great pain. Therefore, we must attach great importance to the discovery and treatment of the disease in order to increase the cure rate of the disease and restore health. Will brain cancer cause nausea? Then let's take a look at the early symptoms of brain tumors.

(1) Headache: It is mostly caused by changes in intracranial pressure and direct infection of the tumor, which stimulates the sensitive structures in the brain, such as the meninges, cerebral blood vessels, venous sinuses and nerves. It is a common early symptom, and 90% of brain tumor patients have headaches. It is mostly throbbing pain or dull pain, which occurs in paroxysmal or continuous manner. It is often more intense and often occurs in the early morning. Sometimes the patient is awakened by the pain during sleep, but the headache will gradually subside or disappear after getting up and exercising slightly. In severe cases, it may be accompanied by nausea and vomiting, and the headache will usually subside after each vomiting. Any cause of increased intracranial pressure, such as coughing, sneezing, or exertion or intense exercise, can aggravate the headache.
(2) Nausea and vomiting: early or first symptoms, often accompanied by headache and dizziness. It often occurs in the early morning on an empty stomach. The typical clinical diagnosis is nausea or projectile vomiting that is unrelated to the tumor diet, and often occurs after a more severe headache or dizziness. Changes in head position can cause or aggravate it. Children with posterior fossa tumors will vomit early and frequently, and it is easy to misdiagnose as a gastrointestinal disease; vomiting in adults will occur later. Nausea and vomiting are caused by increased intracranial pressure or direct infection of the vagus nerve nucleus (vomiting center) by the tumor.
(3) Visual impairment: decreased vision, diplopia, strabismus, visual field (vision range) defects or unilateral exophthalmos caused by non-ophthalmological diseases. When the tumor directly compresses the optic nerve, not only will vision suddenly deteriorate, but blindness may also occur.
