The brain is the control center of the body. It manages everything from movement and balance to memory, speech, and emotions. When a tumour grows in the brain, it can interfere with these functions. The effects of a brain tumour largely depend on its location. Different parts of the brain control different activities, so a tumour in one area can cause specific problems. Understanding which area is affected helps doctors identify the right treatment and manage symptoms.
A tumour is a mass of abnormal cells that grows in the brain. It can be cancerous or non-cancerous. While the size of the tumour matters, the location is often more important in determining how it affects the body. Even a small tumour in a critical area can cause serious issues. Some symptoms develop slowly, while others appear suddenly depending on how the tumour presses on the brain or affects nearby nerves.
Frontal lobe: The frontal lobe is at the front of the brain. It controls personality, behaviour, decision-making, and voluntary movement. A tumour in this area may cause mood changes, irritability, or poor judgement. Patients may also find it hard to plan tasks or make decisions. Since this lobe manages movement, tumours here can cause weakness or paralysis on one side of the body. Some people may also notice trouble walking or coordinating their arms and legs.
Parietal lobe: The parietal lobe is located near the top and middle of the brain. It processes touch, temperature, pain, and spatial awareness. Tumours here may cause numbness or tingling in the body. Patients can find it hard to recognise objects or judge distances. Problems with hand-eye coordination or clumsiness are common. Some may also have difficulty writing, reading, or performing daily tasks that need precise movements.
Temporal lobe: The temporal lobe is located near the ears. It is responsible for hearing, language understanding, and memory. Tumours in this area can affect speech comprehension and cause memory problems. Patients may forget names, places, or recent events. Some may experience seizures, unusual emotional reactions, or difficulty recognising familiar voices. Hearing problems or ringing in the ears can also occur if the tumour grows near auditory nerves.
Occipital lobe: The occipital lobe is at the back of the brain. It processes visual information. Tumours in this area can lead to blurred vision, blind spots, or complete loss of vision in one or both eyes. Patients may also struggle to recognise objects or colours. These visual disturbances can make daily activities, like reading or driving, very challenging. Early detection is important to prevent permanent vision loss.
Cerebellum: The cerebellum is located under the back part of the brain. It controls balance, posture, and coordination. Tumours in the cerebellum can cause dizziness, trouble walking, loss of balance, or frequent falls. Fine motor skills, like writing or buttoning a shirt, may be affected. Some patients may also experience slurred speech or feel unsteady while standing. These symptoms make simple daily tasks difficult.
Brainstem: The brainstem is at the base of the brain and connects to the spinal cord. It controls vital functions like breathing, heartbeat, and swallowing. Tumours in this area are very dangerous. Even small growths can disrupt life-sustaining processes. Patients may have difficulty breathing or swallowing, experience heart rate irregularities, or lose consciousness. Tumours in the brainstem require urgent medical attention due to the high risk to survival.
Other symptoms of brain tumours may include headaches, nausea, vomiting, and seizures. Headaches often worsen in the morning or with physical activity. Seizures can occur in any part of the brain, depending on where the tumour interferes with electrical activity. Early diagnosis is crucial for treatment and preventing permanent damage.
Detecting a brain tumour early improves treatment outcomes. Doctors use imaging tests like MRI or CT scans to locate the tumour and understand its size and growth. Biopsies help determine whether it is cancerous or non-cancerous. Treatment options depend on the type, size, and location of the tumour. Surgery is often used to remove tumours, especially if they are pressing on critical brain areas. Radiation therapy or chemotherapy may also be recommended, particularly for cancerous tumours.

Regular check-ups and monitoring are important for people at risk or experiencing symptoms. Rehabilitation therapies, including physical therapy, occupational therapy, and speech therapy, can help manage symptoms after treatment. Lifestyle changes like a healthy diet, regular exercise, and stress management support overall brain health and recovery.
Understanding how tumour location affects the brain helps patients and families prepare for possible challenges. Knowing what symptoms to watch for allows timely medical attention. While brain tumours can affect many functions, early treatment and proper care can improve quality of life and long-term outcomes.
In conclusion, the location of a brain tumour determines how it affects body functions. Tumours in the frontal lobe affect personality and movement, the parietal lobe affects touch and spatial awareness, the temporal lobe affects memory and hearing, the occipital lobe affects vision, the cerebellum affects balance and coordination, and the brainstem affects vital functions. Early detection, treatment, and rehabilitation are key to managing the effects of brain tumours and protecting health.
