Brain tumours often manifest through subtle symptoms that can easily blend into daily life, leading to delayed diagnosis. According to Dr. Deepak Kumar Singh, Professor and Head of Neurosurgery at Dr. Ram Manohar Lohia Institute of Medical Sciences in Lucknow, early signs may include changes in behavior, such as increased irritability or difficulty concentrating, rather than the expected severe headaches. Family members may notice these changes first, as individuals may become withdrawn or lose interest in activities. Other overlooked symptoms include communication difficulties, balance issues, and a decline in daily functioning. Experts stress that while these signs do not definitively indicate a brain tumour, persistent and progressive symptoms should not be ignored. Advances in neurosurgery now allow for more precise treatment options, making early evaluation crucial for improving outcomes and quality of life. Awareness of these subtle signals is essential, as they may indicate a need for further medical evaluation.
