The reasons for brain tumor recurrence are often related to these three points

Once a brain tumor occurs in many people, there is a possibility of recurrence after effective treatment. So, what are the reasons for the recurrence of brain tumors? The following article will introduce it to you.

1. Local headache

Headache tumors directly compress or pull local pain-sensitive structures, causing fixed-location local headaches accompanied by tenderness outside the local skull. Headaches are usually paroxysmal, with a distending or throbbing pain, and often occur at night or in the early morning. As the tumor grows larger and becomes persistent, the headaches become more widespread as intracranial pressure increases.

2. Visual impairment

Papilledema is caused by impaired retinal venous blood flow due to increased intracranial pressure. It manifests as visual field loss and enlarged blind spot. Visual sensitivity decreases sharply, and severe cases may lead to blindness.

3. Severe vomiting

Headaches often begin with nausea and vomiting, which is caused by stimulation of the vagus nerve center in the medulla oblongata. Usually occurs at night or in the evening or early morning on an empty stomach or when the headache site changes. Vomiting is more common with infratentorial tumors than with supratentorial tumors. Vomiting is often the only symptom of a cerebellar tumor in children.
