Brain tumour symptoms: 7 early warning signs that you should never ignore

When something goes wrong in the brain, it can impact critical functions, and brain tumours are no exception. Often they begin with widely ignored early symptoms, and delayed diagnosis. If you experience recurring headaches, seizures or memory loss, it may be more than just another day’s woes.

Brain Tumour is an abnormal mass of cells within the brain that can be benign (non-cancerous) or malignant. Not all tumours that form in the brain are rapidly or even widely invasive; however, given the cramped quarters within the skull, even a minor tumour can interfere with imperative brain functions. Consequently, early diagnosis and treatment are necessary for a better outcome.

Brain tumours can occur at any age, but some factors can increase the risk of developing them, including genetic, radiation exposure or a family history of cancer. But sadly, the warning signs can often be subtle and mistaken for less serious health problems, such as migraines or stress. So raising awareness is so important as  save lives.

“From memory and vision to movement and emotions, the brain is responsible for everything,” says Dr Ananya Mehta, a neurologist at NeuroCare Institute. “Any irregular growth may affect these processes. Patients frequently wait to see a doctor until symptoms are bad, but catching the disease sooner comes with more treatment options and a greater likelihood of recovery,” she adds.

Here are seven brain tumour warning signs you shouldn't ignore:

Persistent Headaches

Regular headaches, particularly in the morning or during physical activity, can be a sign of abnormal pressure within the skull.

Seizures

Any new or seizures of unexplained origin in an adult should be taken extremely seriously. Immediate medical evaluation is needed.

Vision or Hearing Problems

When a tumour presses on certain nerves or parts of the brain, it may cause symptoms such as blurred or double vision, loss of vision and hearing in one or both ears.

Difficulty with Speech or Memory

Difficulty finding words, hearing and understanding what they are saying and memory losses can indicate disturbances in brain function.

Changes in Balance and Coordination

Unexplained dizziness, balance problems or clumsiness may offer a clue that a tumour in the cerebellum (a region of the brain that coordinates movement) is the cause.

Personality or Mood Changes

Sudden onset irritability, depression or change in behaviour may be associated with a tumour affecting the control of mood centres in the brain.

Nausea and Vomiting

Nausea and vomiting independent of gastrointestinal concerns are associated with hydrocephalus.
