Common symptoms of brain cancer recurrence

What are the common symptoms of brain cancer recurrence? Brain tumors sound scary, because after all, normal people like us don’t come into contact with them very often, so most people are scared when they hear or see brain tumors. However, before we are scared, we must first understand what kind of conditions are considered brain tumors. I hope everyone will take a good look at these conditions and hope that they will be helpful and understandable to patients and friends.

1. Morning headache. Headaches often occur at four or five in the morning and often wake people up from deep sleep, so it is called "morning headache".

2. Projectile vomiting Compared with vomiting caused by gastrointestinal diseases, vomiting caused by brain tumors is not accompanied by stomach distension, nausea, abdominal pain and diarrhea. Vomiting is also unrelated to eating, but "projectile vomiting" occurs suddenly after a headache.

3. Visual impairment. When brain tumors cause increased intracranial pressure, blood flow in the ophthalmic veins is blocked, leading to stasis and edema, which damages the visual cells on the retina and causes decreased vision. Some patients experience incomplete visual field defects.

4. Monocular exophthalmos. This means that one eyeball protrudes forward, which in severe cases leads to incomplete eyelid closure.

5. Olfactory hallucinations occur because the temporal lobe located in the lower part of the brain is stimulated by the tumor. Patients often smell odors that do not actually exist, such as burning rubber, burnt rice, or fragrance.

6. Transient misrecognition of people. People with temporal lobe brain tumors may also feel strange and familiar with people, and this symptom can last for several minutes.

7. Decreased sensation. A tumor in the parietal lobe, located in the middle of the cerebral hemisphere, can cause a decrease in the senses of the opposite side of the body, including pain, heat, cold, touch, vibration, and body shape identification.

8. Unilateral deafness. If there is no history of otitis media, but only one ear has hearing loss, it is likely caused by an intracranial tumor compressing the auditory nerve.

9. Late-onset epilepsy: If epilepsy begins to occur in adulthood and there are no other triggers, a brain tumor should be considered first.
