What are the main early symptoms of brain cancer

Brain cancer does not account for a high proportion of all cancers. Its symptoms are very subtle. Many people often ignore the warnings of brain cancer and neglect their health. By the time they discover it, it is too late. The following article is about the main early symptoms of brain cancer. Welcome to read, thank you!

What are the main early symptoms of brain cancer?

Morning headache

Headaches often occur at four or five in the morning, and often wake people up from deep sleep. The headaches gradually ease or disappear after getting up and doing some light activities, so they are called "morning headaches." Tumors in the posterior cranial fossa can cause neck pain that radiates to the eye sockets, and the severity of the headaches gradually increases as the disease progresses.

Projectile vomiting

Compared with vomiting caused by gastrointestinal diseases, vomiting in patients with brain tumors is not accompanied by abdominal distension, nausea, or diarrhea. However, when intracranial pressure increases, "projectile vomiting" may occur after a headache.

Visual impairment

Increased intracranial pressure can cause venous blood in the eye to flow back to the brain poorly, leading to edema and decreased vision. In severe cases, the retina may have punctate, linear, or flaky lesions or even bleeding, causing blurred vision.

Mental disorders

Brain tumors located in the frontal lobe of the brain can destroy the mental activities of the frontal lobe, causing abnormal mental manifestations such as excitement, agitation, depression, and depression.

Phantosmia

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, etc.

One eye protrudes

That is, one eyeball protrudes forward, and in severe cases the eyelid does not close completely. The most common cause is a brain tumor.

Decreased sensation

The parietal lobe, located in the middle of the cerebral hemisphere, is responsible for sensation. Tumors in this area can cause decreased or absent sensations such as unilateral limb pain and body shape discrimination.

Unilateral deafness

If there is no history of otitis media or trauma, and only one ear has progressive hearing loss, accompanied by tinnitus on the same side, it is likely caused by an intracranial tumor compressing the auditory nerve.
