Subtle signs of a brain tumor can include personality changes, persistent headaches (worse in the morning), memory/concentration issues, mild weakness or numbness on one side, vision changes (blurry, double), unexplained fatigue, balance problems, new seizures, difficulty finding words, or subtle hearing loss, often developing slowly over time. These symptoms can be easily dismissed but signal a problem, especially when they worsen or don't respond to usual treatments, requiring medical evaluation.
General signs and symptoms caused by brain tumors may include:
Some of the first signs of a brain tumor may include:
Difficulty thinking, speaking or disorientation – Confusion in everyday matters, such as what day it is, when they last ate, or remembering people's names can be an indicator. Changes in personality – Sudden shifts in mood, such as irritability, panic attacks, and delusions, can result from a brain tumor.
In addition to a headache, a low-grade glioma can cause other symptoms that can be felt, such as:
The early stage of a brain tumor can manifest as persistent or severe headaches, seizures, cognitive changes, vision problems, personality changes, balance issues, fatigue, nausea/vomiting, speech difficulties, or loss of smell. Brain tumor symptoms may vary in intensity and duration.
Conditions like epilepsy, stroke or Parkinson's disease can cause similar symptoms to brain tumors. And headaches are much more likely to be caused by something other than a brain tumor.
Brain tumor red flags include persistent, worsening headaches (especially in the morning/night), new-onset seizures, unexplained nausea/vomiting, vision changes (blurred, double), balance/coordination issues (clumsiness, trouble walking), significant personality or behavioral shifts, weakness/numbness on one side, and speech difficulties (slurring, trouble finding words). These symptoms often stem from increased pressure or direct interference with brain functions, and their gradual or sudden appearance warrants medical attention.
What is pseudotumor cerebri? Pseudotumor cerebri literally means "false brain tumor." It is likely due to high pressure within the skull caused by the buildup or poor absorption of cerebrospinal fluid (CSF). The disorder is most common in females between the ages of 20 and 50.
Numbness or weakness on one side of the body, in your arms or legs, or a tingling sensation can indicate a brain tumor. If you notice these symptoms, immediate medical attention is important. Sudden and unexplained changes in personality, behavior, and mood swings can be signs of a brain tumor.
We sometimes find brain tumors when otherwise healthy people suddenly have a seizure, unusual weakness or speech problems. If you have these symptoms, go to an emergency room. If ER doctors suspect a brain tumor, they may send you to us for a full evaluation.
Experiencing non-existent foul smells and odours could be sign of cancer growing in the olfactory cortex or invading it from neighbouring tissues.
Brain Tumor Causes and Risk Factors
Doctors don't know why some cells begin to form into tumor cells. It may have something to do with a person's genes or his or her environment, or both. Some potential brain tumor causes and risk factors may include: Cancers that spread from other parts of the body.
Symptoms of a brain tumour
As non-cancerous tumours tend to grow slowly, the symptoms usually come on gradually and may get worse slowly over months or years. Symptoms of a brain tumour can include: headaches that get worse over time or do not go away – although it's unusual for a headache to be the only symptom.
Brain tumor misdiagnosis can commonly be diagnosed as these diseases:
Symptoms of meningioma
Intracranial hypertension's clinical manifestations vary depending on the underlying cause, severity of pressure elevation, and individual patient factors. Common symptoms may include severe headaches, visual disturbances, nausea, vomiting, tinnitus, and, in severe cases, seizures or coma.
PET-CT scan
The PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal. You might have a PET-CT scan of the brain to help diagnose your brain tumour. It can help your doctor: diagnose your tumour and help them take a sample of cells (biopsy)
Knowing how to distinguish between a typical headache and one caused by a brain tumor is essential for timely medical attention. The most important difference is that brain tumor headaches tend to be persistent, worsening over time, and often occur at night or in the early morning.
The symptoms of a brain tumour can include headaches, changes in vision, tiredness, a loss of taste and smell, nausea and dizziness. If you are experiencing any of these, consider booking a checkup with your GP.
Because this condition causes symptoms of elevated pressure in the head – which is also seen with large brain tumors – but have normal scans, the condition has been called pseudotumor cerebri, meaning “false brain tumor”. Pseudotumor cerebri symptoms include headache and blurred vision, which can increase over time.
Anxiety can also show up in physical ways, like shaking, feeling sick, or having trouble focusing. These symptoms can be mistaken for signs of a brain tumor.
Brain tumours lack metabolic versatility and are dependent largely on glucose for energy. This contrasts with normal brain tissue that can derive energy from both glucose and ketone bodies.
