Brain Tumor: How does brain tumor occur and what are its dangers? Detailed information given by experts

Pune : A brain tumor is usually associated with severe headache symptoms. But according to experts, some of the early symptoms of a brain tumor can be very subtle. Symptoms include behavioral changes, vision problems, memory loss, and even unexplained seizures. Many people ignore it or see it as a stress, aging, lifestyle related problem.

On World Brain Tumor Day 2026, neurologists have urged citizens to be aware of these lesser-known symptoms. Because early diagnosis can significantly improve treatment outcomes. Changes in Behavior and Personality, an Often Ignored Warning The most overlooked symptom of a brain tumor is a sudden change in behavior or personality. Family members may notice that a person has become unusually aggressive, aloof, emotionally unstable, or has decreased judgment and judgment.

Aditya Birla Memorial Hospital, Pune Senior Director – Neurosciences and Neurosurgeon Dr. According to Rakesh Ranjan, a tumor in the frontal lobe (the front part of the brain) can cause changes in behavior, emotions and social interactions. So families often mistake these symptoms for stress, depression or mental health issues. Vision problems should not be ignored. Frequent blurred vision, double vision, difficulty focusing, or loss of side vision can be signs of pressure on the brain’s visual pathways. A neurological examination should be performed if vision problems persist in the absence of any obvious eye-related disease.

First-time seizures in adults should be investigated immediately

A seizure in an adult with no prior history of epilepsy should never be ignored. Because unexplained seizures can be an early sign of a brain tumor or other serious neurological disorder. Symptoms such as memory loss and speech difficulties with increasing forgetfulness, difficulty finding the right words, confusion in daily activities or changes in speech are often associated with advancing age. However, if these symptoms appear suddenly or increase gradually, a medical examination is necessary.

Symptoms of a tumor vary depending on its location

Brain tumor symptoms can vary from person to person, as different parts of the brain control different functions. A tumor in the frontal lobe can cause behavioral changes, while a tumor in the temporal lobe (the area near the top of the ear) can affect memory and speech. Tumors near the cerebellum (cerebellum) can cause problems with balance and coordinating movements.

Children may have different symptoms

In young children, persistent vomiting, headaches, body balance problems, developmental delays, changes in academic performance, or irritability can be warning signs of a brain tumor and danger. It is very important for parents and caregivers to recognize these symptoms early so that treatment can be started in time.

Timely scanning can save lives

Advanced diagnostic technologies such as MRI and CT scan have made early diagnosis of brain tumors possible. According to experts, timely scanning can lead to early treatment planning and help improve patients’ life expectancy and quality of life.

Misunderstandings lead to delays in treatment

A common misconception is that all brain tumors are cancerous or incurable. Many tumors are actually benign and can be effectively managed with surgery, radiation therapy, targeted therapy, or a combination of different treatments. Delay in seeking medical advice can often be more dangerous than the tumor itself.
