How can you tell if have brain cancer?

Possible symptoms of brain cancer can include:

- Persistent headaches. Headaches are a common symptom of brain cancers, especially those located in the brain's frontal lobes. These headaches may be severe and unrelieved by over-the-counter pain medication.

- Seizures. Seizures are another common symptom of brain cancer, particularly in people who have been diagnosed with glioblastoma, the most common type of malignant brain cancer. Seizures can range from mild to severe and may occur at any time.

- Vision changes. Vision changes, such as blurred vision, double vision, or loss of peripheral vision, can be a sign of brain cancer. These changes can occur when the tumor presses on or damages the optic nerves or other parts of the brain responsible for vision.

- Speech difficulties. Speech difficulties, such as slurred speech or difficulty finding words, can be a symptom of brain cancer. These difficulties can occur when the tumor affects the areas of the brain responsible for speech and language.

- Motor weakness. Motor weakness, such as weakness in one side of the body or difficulty walking, can be a symptom of brain cancer. This weakness can occur when the tumor affects the areas of the brain responsible for movement.

- Nausea and vomiting. Nausea and vomiting can be symptoms of brain cancer, especially in people who have been diagnosed with a tumor in the cerebellum. These symptoms may be caused by the increased pressure on the brain or the disruption of the brain's normal function.

- Personality changes. Personality changes, such as irritability, apathy, or difficulty concentrating, can be symptoms of brain cancer. These changes can occur when the tumor affects the frontal lobes or other areas of the brain responsible for personality and behavior.

- Cognitive problems. Cognitive problems, such as memory loss, confusion, or difficulty thinking, can be symptoms of brain cancer. These problems can occur when the tumor affects the temporal lobes or other areas of the brain responsible for cognition.

It is important to note that these symptoms can also be caused by other conditions, so it is essential to see a doctor if you are experiencing any of these symptoms to determine their cause.
