Early detection of brain tumour is vital, as it can accelerate treatment and help lead to morbidity free survival, said doctors on Tuesday. World Brain Tumour Day is observed on June 8 every year to increase awareness and to educate the public about brain tumours. Brain tumours are abnormal growths that develop within the brain or its surrounding structures. They can be benign (non-cancerous) or malignant (cancerous). The prevalence of brain tumours in India is a growing matter of concern.

"Almost 40,000 new cases of brain tumours are diagnosed each year in the country. Prevention of brain tumours is challenging as most cases are not associated with identifiable risk factors," Dr. Amit Shrivastava, Director & Senior Consultant - Neurology at Dharamshila Narayana Superspeciality Hospital, told IANS.
