A brain tumor can be hard to detect because the symptoms often look like other common health issues.
Here are some crucial things to know about warning signs, diagnosis, and when to see a doctor.
Headaches

More than half of people with brain tumors experience headaches that tend to get worse over time. This happens because the tumor increases pressure inside the skull.
Seizures

About half of all people with a brain tumor will have at least one seizure. For some, a seizure might even be the first noticeable symptom.

Vision changes

Blurry vision or other visual changes can signal that a tumor is affecting the part of the brain that controls eyesight.
Personality changes

Some people with brain tumors notice sudden changes in their mood or personality, which can easily be mistaken for stress or mental health issues.
Balance and coordination problems

A tumor can interfere with the brain’s control of movement, making it harder to keep your balance or coordinate simple tasks.
Ongoing fatigue

Extreme tiredness that doesn’t improve with rest could be a sign that something is affecting brain function.

Nausea and vomiting

Frequent nausea or vomiting that can’t be linked to stomach issues may, in rare cases, be related to increased pressure in the brain.
You can’t diagnose yourself

It’s impossible to diagnose a brain tumor on your own because so many other conditions cause similar symptoms.
A doctor needs to run imaging tests like MRI or CT scans.
Other conditions can look similar

Many health issues, like stroke, intracranial abscess, or pseudotumor cerebri, can cause the same symptoms as a brain tumor.
