Analyze the early symptoms of brain cancer

Brain cancer is generally not obvious in the early stages. It grows inside the patient's skull and gradually becomes apparent as the disease worsens. So what are the early symptoms of brain cancer ? Here are the detailed answers from relevant experts.

1. Decreased sensation: The parietal lobe located in the middle of the cerebral hemisphere is responsible for sensation. Brain cancer in this area can cause unilateral limb pain and decreased or absent sensation such as body shape discrimination. This is an early symptom of brain cancer.

2. Visual impairment: Increased intracranial pressure can cause edema due to poor venous blood return to the brain, leading to decreased vision. In severe cases, the retina may have punctate, linear, or flaky lesions or even bleeding, causing blurred vision.

3. Olfactory hallucinations: Olfactory hallucinations occur because the temporal lobe located in the lower part of the brain is stimulated by the tumor. Brain cancer patients often smell odors that do not actually exist, such as burning rubber, burnt rice, etc.

4. Morning headache: Headache is a common symptom of brain cancer, often occurring at four or five in the morning. People are often awakened by the pain while sleeping. The headache gradually eases or disappears after getting up and doing some light activities, so it is called "morning headache". Tumors in the posterior cranial fossa can cause neck pain that radiates to the eye sockets, and the severity of the headache gradually increases as the disease progresses.

The above is an introduction to the early symptoms of brain cancer. If you experience the above symptoms, you must go to the hospital for treatment in time. If you want to know more about brain cancer, please consult online experts.
