Three major symptoms of brain cancer

Brain cancer, also known as intracranial tumors, can originate from the brain, meninges, nerves, blood vessels and brain appendages, or metastasize from other tissues or organs in the body and invade the brain. Most of them can cause headaches, intracranial hypertension and focal symptoms. So what symptoms will appear if you have brain cancer?

Brain cancer symptom 1: visual impairment

It is caused by increased intracranial pressure, which causes papilledema. Papilledema can be detected with an ophthalmoscope. Patients may experience decreased vision, blurred vision, diplopia, hemianopsia or blindness.

Brain cancer symptom 2: vomiting

Vomiting often occurs in the morning or when the headache is severe. The vomiting is jet-like, without nausea, and has nothing to do with diet. Compared with vomiting caused by gastrointestinal diseases, vomiting in patients with brain tumors is not accompanied by abdominal distension, nausea, abdominal pain, and diarrhea. Instead, "jet-like vomiting" suddenly occurs after a headache. Because the increased intracranial pressure stimulates the respiratory center of the medulla oblongata, this characteristic jet-like vomiting will occur. Some children with brain cancer, who cannot express other symptoms, often use unexplained jet-like vomiting as a criterion for the early stage of the disease.

Brain cancer symptom three: headache

Headache is the most common symptom of brain cancer. It often occurs intermittently in the early stage, and then develops into persistent and progressive pain. The nature of the pain may be throbbing dull pain, distending pain, compressive pain, or splitting pain. The location of the headache is mostly in the forehead, both temporal regions, or the occipital region. The location of the pain is not consistent with the location of the tumor.

This type of headache often occurs at four or five in the morning, and often wakes you up from a deep sleep. The deeper you sleep, the more severe the pain. After getting up and moving around, the headache gradually eases and even disappears at eight or nine o'clock, so it is called a "morning headache", which is a major sign unique to brain tumors. The mechanism of this "morning headache" is that the brain tumor partially obstructs the normal circulation of cerebrospinal fluid, especially after a good night's sleep, forming transient hydrocephalus, causing severe headaches and waking up with pain. Getting up and moving around can speed up the circulation of cerebrospinal fluid, so the headache can be relieved.

Through the above introduction, we know the three major symptoms of brain cancer. I believe everyone has a certain understanding of the symptoms of brain cancer.
