Is it painful to have a recurrence of brain cancer?

Tumors that grow in the brain are generally called brain tumors, including primary brain tumors that originate from the brain substance and secondary brain tumors that metastasize from other parts of the body to the brain. The causes are complex and prone to recurrence, so you need to be alert to the signs of brain tumor recurrence. So is it uncomfortable to have a brain cancer recurrence?

1. Headaches Tumors directly compress or pull local pain-sensitive structures, which can cause localized headaches with fixed locations and tenderness outside the skull. Headaches are usually paroxysmal, with swelling or throbbing pains, and often occur at night and in the early morning. As the tumor gradually grows, it eventually becomes persistent. When intracranial pressure increases, the headaches tend to be widespread.

2. Visual field impairment: The retinal venous blood flow disorder caused by increased intracranial pressure leads to optic disc edema, which manifests as visual field loss and enlarged blind spot.

3. Severe vomiting. Nausea and vomiting usually occur first when the headache is severe. This is caused by the stimulation of the vagus nerve center in the medulla oblongata. It usually occurs at night or in the early morning when the stomach is empty or the headache site changes. Vomiting is more common in infratentorial tumors than in supratentorial tumors. Vomiting is often the only symptom of cerebellar tumors in children.

4. Epileptic seizures Generalized epileptic seizures may be related to increased intracranial pressure, but they may also be the local effect of brain tumors.
