Brain tumours affect thousands of people every year, yet many cases are diagnosed only after symptoms become severe. One of the biggest challenges in managing brain tumours is that early warning signs are often subtle and mistaken for stress, fatigue, or routine health issues. Medical experts stress that recognising these early signals can significantly improve outcomes and quality of life.
Recently, renowned neurosurgeon Dr Jay Jagannathan highlighted the importance of early detection in a post shared on Instagram. Drawing from years of clinical experience, he noted that many patients tend to overlook minor symptoms, only to later discover that they were early indicators of a brain tumour. “Over my years in neurosurgery, I’ve seen patients brush off subtle symptoms — only to discover a brain tumour later. Early detection can make all the difference,” he wrote.
What is a brain tumour?

According to medical experts, including information commonly referenced by institutions such as the Cleveland Clinic, a brain tumour is an abnormal growth of cells within the brain or surrounding areas. These tumours can be benign (non-cancerous) or malignant (cancerous). While benign tumours may grow slowly, they can still cause serious complications by pressing against sensitive brain tissue. Malignant tumours, on the other hand, tend to grow faster and may spread, posing a greater risk to life.
Regardless of type, brain tumours can interfere with vital brain functions such as memory, vision, speech, and movement. The symptoms largely depend on the tumour’s size, growth rate, and exact location in the brain.
Five early signs people often ignore
Dr Jagannathan shared five early warning signs that many individuals dismiss, assuming they will resolve on their own. He cautioned that persistent or worsening symptoms should never be ignored.
1. Persistent or unusual headaches
Headaches are common and often harmless, but concern arises when they become persistent, severe, or different from a person’s usual pattern. Headaches caused by brain tumours may worsen over time or feel more intense in the morning.
2. Changes in vision
Vision problems such as blurred vision, double vision, or loss of peripheral (side) vision can indicate pressure on parts of the brain responsible for sight. These changes may appear gradually and are often overlooked until they interfere with daily activities.
3. Cognitive difficulties and memory lapses
Trouble concentrating, frequent forgetfulness, or difficulty finding the right words can signal changes in brain function. While occasional lapses are normal, consistent cognitive issues deserve medical attention.
4. Personality or mood changes
Sudden mood swings, irritability, anxiety, or depression without an obvious cause may be linked to changes in specific brain regions. Family members are often the first to notice these shifts.
5. Seizures, tingling, or numbness
An unexpected seizure, or persistent tingling and numbness in the arms, legs, or face, can be a serious neurological warning sign. Even a single seizure episode should prompt immediate medical evaluation.
Dr Jagannathan emphasized that many patients initially blame these symptoms on stress or lifestyle factors. “I’ve seen patients dismiss these signs thinking it’s stress. Early evaluation often changes everything,” he said.
Frequently asked questions about brain tumours
What causes brain tumours?
Brain tumours may develop due to genetic mutations, exposure to radiation, or environmental factors. In many cases, the exact cause remains unknown.
How are brain tumours diagnosed?
Doctors typically use imaging tests such as MRI or CT scans to detect tumours. A biopsy may be performed to determine whether the tumour is benign or malignant.
What treatment options are available?
Treatment depends on the type, size, and stage of the tumour and may include surgery, radiation therapy, chemotherapy, targeted therapy, or immunotherapy.
Can brain tumours be prevented?
Not all brain tumours can be prevented. However, maintaining a healthy lifestyle and avoiding known risk factors may help reduce overall risk.
Awareness of early symptoms plays a crucial role in timely diagnosis and effective treatment. If unusual neurological symptoms persist or worsen, seeking medical advice promptly can be life-saving.
