Brain cancer is one of malignant tumor that attacks the brain. It occurs due to abnormal cell growth in the brain. The brain cancer early symptoms are not usually recognized.  It makes this condition gets worse. Most of the people are not aware of the symptoms that appear. It makes them late knowing that they have brain cancer.

The Most Common Brain Cancer Early Symptoms

It is not exactly known what actually causes the brain cancer. But some researchers suspect that it is caused by genetic factors, chemical exposure, and frequent radiation.

Brain Cancer Early Symptoms to Beware of

Some studies indicate 11 brain cancer early symptoms that people to notice and beware

1. Headache

A headache might occur to everyone. But this is one of the most common brain cancer early symptoms. 38 of 50 respondents or 76 % have this symptom. Of course, many people experience a headache. According to Dr. Santiago Medina, a co-director of Radiology Sub Neuroradiology Department in Miami Hospital, from 4 thousand children who experience a headache, one of them had brain cancer. How to distinct a headache as a brain cancer symptom from a common headache?

  • It is really new. If you have never had this symptom before, or it is rare, but currently you get this symptom frequently, you are suggested to have medical checks.
  • It is accompanied by other symptoms. A headache as the symptom of brain cancer usually comes with other symptoms such as nausea and vomiting. In the worse condition, it might come along with seizures, blurred vision, and difficulty speaking.
  • It starts from when you wake up in the morning. You need to beware if you experience a headache that starts in the morning when you wake up along with nausea and vomiting and it quit in the afternoon and it happens almost every day.
  • It is getting worse. If this headache is a brain cancer symptom, it always comes time after time, repeatedly until a couple of months. If you experience this, consult the doctor as soon as possible.


  • CT-Scan. It is the most common imaging test taken to diagnose brain cancer
  • MRI Scan. An imaging test from the inside of the brain to diagnose the level of damage.

2. Mental and Personality Changes

Brain cancer makes the brain doesn’t function normally. The patients will experience some symptoms include concentration disorder, memory loss, sleep intensity increase, personality and behavior changes, and reasoning problems. A study indicates that 32 over 50 brain cancer survivors experience these symptoms.

3. Vomiting

A research indicated some evidence that 26 over 50 brain cancer survivors (52%) experience vomiting. It usually occurs in the morning and usually comes all of sudden with a terrible headache.  As it was said before, vomiting and headache are the common health problems that often occur to many people, so it is difficult enough to distinguish whether these symptoms are signs of brain cancer. Some point to recognize if the vomiting is one of the brain cancer early symptoms include:

  • Comes all of sudden (without suffering from any illness)
  • It comes with a terrible headache

4. Vision Problems

46% brain cancer survivors experience this symptom. These are some signs that point the vision problems as symptoms of brain cancer:

  • Seeing lights as blinking
  • Blurred vision
  • Only able to see straight
  • When they are reading, the text seems to disappear

These vision problems are caused by eye nerve damage due to the brain cancer in the certain areas of the brain.

5. Difficulty Moving

Cancer cells that attack the brain restrict the brain function control the body movement. Someone with brain cancer will walk with unbalance movement, difficult to control the motoric and it causes her/him to drop something and often fall down when walking.

6. Seizures

60% of brain cancer survivors experience seizures. It occurs because the motoric activity in the brain works abnormally. According to American Brain Tumor Association, the characteristics of seizures in brain cancer survivors include:

  • It comes all of sudden (without any sign)
  • Followed by consciousness loss and muscle contraction
  • Body control loss
  • Biting tongue
  • Short-term duration (2-3 minutes)
  • Breathing stops for 30 seconds and the body turns into livid.
  • numbness

The seizures might occur at least once within the life period of brain cancer cells. It is caused by abnormal brain electrical activities. Usually, the body nerves communicate each other and cooperate through the electrical signals controlled properly. If something attacks and disturbs these signals, they will be more intense and cause seizures.

Most of the seizures occur randomly, all the time and without any causes and signs. But in several cases, some individuals might see the “signals”. It is usually called as “aura”. Sometimes, an aura can be a headache, mood changes, certain aroma, and muscles twitch.

7. Dementia

For certain brain cancer survivors, dementia might occur as one of the brain cancer early symptoms. It is rare enough, only 14% of the survivors experience dementia.

8. Consciousness Problem

This consciousness problem is a symptom that might come before consciousness loss. Some indications of this symptom include get shocked easily, absentminded, and forget easily about what they are doing.

9. Extreme Weight Loss

Extreme weight loss that occurs in brain cancer survivors is alleged because the abnormal cognitive and activity that affect the body metabolism. It affects to the weight loss.

10. Expression and Sensation Loss

Expression and sensation loss are related to the brain function development that is disturbed by cancer cells. The brain doesn’t function normally and it affects the mind. The individual, who has this symptom usually just express flat, can’t think, and the cognitive ability is decreasing.

11. Anorexia/ Appetite Loss

Some studies found that 4% if brain cancer survivors experience anorexia. However, it is still under further research whether anorexia can be categorized as one of the brain cancer early symptoms.

Based on the location of the cancer cells, brain cancer causes several more specific symptoms.

  1. Frontal Lobe. The symptoms include personality changes, apathies, aggressive (get angry easily), sense of smell loss, difficulty organizing, voice problem, vision problem
  2. Temporal Lobe. The symptoms include memory problem (forget some words or names), difficulty speaking because they can’t find the right words, short-term memory loss, and hearing echoing sound inside the head.
  3. Parietal Lobe. The symptoms include difficulty speaking or understanding what someone says, numbness, difficulty reading and writing.
