Brain tumors form when brain cells grow and divide uncontrollably. Brain cancer refers to malignant tumors that develop in the brain, comprising two main types: primary brain cancer and secondary brain cancer (which metastasizes from other parts of the body). Initial symptoms of brain cancer are often subtle, easily mistaken for common health issues. Headaches are frequently a primary and early symptom, though they can sometimes be accompanied by other signs.

Nausea and vomiting are common early indicators of a brain tumor, often accompanying headaches. The growing tumor inside the skull creates pressure, disrupting brain activity. These symptoms are often overlooked because they resemble common health problems, making early medical consultation advisable if unusual symptoms persist.

Early-stage brain cancer can also manifest as cognitive problems, affecting memory, concentration, mood, and leading to irritability. These cognitive changes occur because the tumor compresses brain regions that control thought processes and emotional responses. Individuals may experience confusion, difficulty communicating, and trouble recognizing behaviors. These subtle changes often go unnoticed or are attributed to stress and aging due to their gradual progression. However, brain tumor patients can develop cognitive changes before overt neurological symptoms appear.

Unexplained muscle weakness or paralysis, along with seizures, can signal a brain tumor located in the brain's motor region. If such conditions appear suddenly, are unusual, and have not been experienced before, seeking prompt medical attention is recommended.

Vision problems are another significant symptom, as brain tumors can affect the brain's visual processing centers and optic nerves. This can result in blurred vision, double vision, flashing lights, and peripheral vision loss. These symptoms differ from typical eye strain because they either progress or appear without an obvious cause.

Brain cancer often causes profound and persistent fatigue that goes beyond normal tiredness and does not improve with rest. Individuals with brain tumors frequently experience extreme exhaustion, making daily activities difficult and affecting their ability to stay alert. Additionally, balance and coordination disorders can arise when the brain's motor control is compromised.
