What are the early symptoms of brain cancer?

If there is a tumor in the brain, it means you have brain cancer. When you have brain cancer, you will experience severe pain in the brain. So, what are the common early symptoms of brain cancer ? Next, let's learn about it from the following article.

1. Visual impairment: Early symptoms of brain cancer include changes in vision, visual field and fundus. Due to increased intracranial pressure, optic disc edema occurs or the tumor directly compresses the optic nerve, which can cause optic nerve atrophy and affect vision over time, resulting in vision loss or even blindness. The reason why brain cancer patients may develop optic disc edema is that the increased intracranial pressure restricts the return of lymph in the lymphatic sheath around the optic nerve, increases the pressure of the ocular veins, and causes venous congestion.

2. Headache: Another early symptom of brain cancer is increased intracranial pressure or direct compression and stimulation of the meninges, blood vessels, and nerves by the tumor. It is seen in most patients and is an early symptom that worsens with the development of brain cancer.

3. Vomiting: It is mostly caused by increased intracranial pressure stimulating the medullary vomiting center and vagus nerve stimulation. When the headache is severe, vomiting is often jet-like. Children with posterior cranial fossa tumors will have early and frequent vomiting, which can be easily mistaken for gastrointestinal diseases. This is also an early symptom of brain cancer.

The above is a detailed description of the early symptoms of brain cancer. I hope it can help everyone understand the knowledge of brain cancer and cure it in time. If you have other questions about brain cancer, you can contact our online experts to answer your questions.
