Neurosurgeon shares 5 hidden signs of brain tumour people often overlook

As per Mayo Clinic, brain tumours are abnormal cell growths in or around the brain, and they can be cancerous or non-cancerous – while some aren't cancerous, brain cancers may grow quickly.

That is why it is important to watch out for symptoms and see a doctor if they are persistent or worsening to get a proper evaluation and early diagnosis.

'Early detection can make all the difference'

Dr Jay Jagannathan, neurosurgeon, Jagannathan Neurosurgery Institute, took to Instagram on September 22 to share 'hidden signs of a brain tumour' that you might be overlooking. He said, "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."

Symptoms to watch out for

"I've seen patients dismiss these signs, thinking it's stress — early evaluation often changes everything," he said.  

According to Dr Jagannathan, here are '5 surprising signs people often overlook':

1. Persistent headaches that feel different from usual.

2. Vision changes – blurry, double, or loss of peripheral vision.

3. Cognitive changes – memory lapses, trouble concentrating, or finding words.

4. Personality or mood shifts – sudden irritability or depression.

5. Seizures or unusual tingling/numbness – even a single episode matters.

In a July 2025 interview with HT Lifestyle, Dr Rohit Bansil, associate director, neurosurgery and neurospine, BLK - MAX Super Speciality Hospital, had said, "The early detection of brain tumours and early intervention is very vital for the treatment outcome and overall survival."
