Brain Tumours: Signs, Causes, And How To Treat

A brain tumor is an abnormal growth of cells in the brain. It can affect how the brain works and cause various health issues. While the exact cause of brain tumors is not always clear, certain factors like genetic mutations or exposure to radiation may play a role in their development.

Understanding the nature of brain tumors and seeking timely medical advice is crucial for proper management and care. If you have concerns about your brain health or experience unusual symptoms, consult with a healthcare provider for personalized guidance and support.

What Are the Symptoms of Brain Tumours

Brain tumor symptoms include headaches, seizures, changes in vision, speech difficulties, memory problems, and balance issues. Other signs may include nausea, vomiting, and personality changes.

If you experience persistent or worsening symptoms, seek medical attention promptly for a proper evaluation and diagnosis. Early detection is crucial for effective treatment and management of brain tumors.

Persistent headaches that are severe and do not improve with rest or pain medication can be a symptom of a brain tumor.
Sudden changes in vision, such as blurry vision, double vision, or loss of peripheral vision, may indicate a brain tumor and should be evaluated by a healthcare provider.
Difficulty with balance and coordination, leading to stumbling, clumsiness, or difficulty walking, could be a sign of a brain tumor affecting the cerebellum.
Cognitive changes like memory problems, confusion, difficulty concentrating, or personality changes may signal a brain tumor impacting cognitive function.
Seizures, especially if they occur suddenly in someone who has never had seizures before, can be a symptom of a brain tumor and require

Causes of Brain Tumours

Environmental factors like smoking and exposure to certain chemicals may also play a role. Additionally, age, gender, and family history can be contributing factors. In some cases, the exact cause of a brain tumour may remain unknown.

Genetic mutations in the DNA of brain cells can lead to the development of brain tumors.
Exposure to ionizing radiation, such as radiation therapy for previous head or neck cancers, is a risk factor for brain tumor formation.
Certain inherited genetic syndromes, like neurofibromatosis or Li-Fraumeni syndrome, can predispose individuals to brain tumors.
Prolonged exposure to environmental toxins or chemicals, such as certain industrial solvents, may increase the likelihood of developing a brain tumor.
Chronic inflammation in the brain caused by conditions like meningitis or autoimmune disorders can contribute to the growth of tumors in the brain.

Types Of Brain Tumours

There are two main types of brain tumors: primary and metastatic. Primary tumors start in the brain itself, while metastatic tumors spread to the brain from other parts of the body. Primary tumors can be benign or malignant, with gliomas being the most common type. Metastatic tumors are typically more aggressive. Treatment options and outcomes vary depending on the type of tumor.

Glioblastoma Multiforme: This aggressive type of brain tumor is known for its fast growth and high likelihood of recurrence, making it one of the most challenging to treat.
Meningioma: A common type of brain tumor that develops in the meninges, the protective layers surrounding the brain and spinal cord, and is often slow-growing and noncancerous.
Medulloblastoma: Primarily affecting children, this type of brain tumor arises in the cerebellum and can lead to symptoms such as headaches, nausea, and balance problems.
Pituitary Adenoma: Originating from the pituitary gland, this type of brain tumor may cause hormonal imbalances

Risk Factors

Risk factors for brain tumors include exposure to ionizing radiation, family history of brain tumors, certain genetic syndromes, and increasing age. Other possible risk factors may include a history of head injuries, exposure to certain chemicals, and having a weakened immune system. It's important to be aware of these risk factors and consult with a healthcare provider for appropriate screening and monitoring.

Family history of brain tumours increases the risk of developing one, as certain genetic factors may predispose individuals to this condition.
Exposure to ionizing radiation, either through radiation therapy for other medical conditions or environmental factors, can elevate the risk of developing a brain tumour.
Certain inherited genetic syndromes, such as neurofibromatosis or Li-Fraumeni syndrome, are associated with a higher likelihood of developing brain tumours.
Age is a significant risk factor, with brain tumours more commonly diagnosed in older adults, although they can occur at any age.
Individuals with a compromised immune system, such as those with HIV/AIDS or undergoing organ transplantation, are at an increased risk of developing brain

Diagnosis of Brain Tumours

Your doctor will review your symptoms, medical history, and imaging results to make a diagnosis. It's important to follow your healthcare provider's recommendations for accurate diagnosis and treatment planning. Trust your healthcare team to guide you through this process with care and expertise.

Imaging tests such as MRI and CT scans are commonly used to detect brain tumors by providing detailed images of the brain.
Biopsy involves the removal of a small sample of tissue from the brain for examination under a microscope to confirm the presence of a tumor.
Neurological exams assess a patient's reflexes, coordination, and sensory functions to detect any abnormalities that may indicate a brain tumor.
Blood tests can help identify certain markers that are associated with brain tumors, although they are not definitive diagnostic tools on their own.
Lumbar puncture, also known as a spinal tap, may be performed to analyze the cerebrospinal fluid for signs of abnormalities linked to brain tumors.

Treatment for Brain Tumours

Treatment options for brain tumors may include surgery, radiation therapy, and chemotherapy. Surgery aims to remove the tumor, while radiation therapy uses high-energy beams to target cancer cells. Chemotherapy involves medications to kill cancer cells. Other treatments like targeted therapy and immunotherapy may also be considered depending on the type and stage of the tumor. Your healthcare team will create a personalized treatment plan for you.

Surgery is often the primary treatment for brain tumors, aiming to remove as much of the tumor as possible while preserving healthy brain tissue.
Radiation therapy uses high-energy beams to target and destroy cancer cells in the brain, either as a standalone treatment or in combination with surgery and/or chemotherapy.
Chemotherapy involves the use of powerful medications to kill cancer cells or slow their growth, and may be administered orally, intravenously, or directly into the cerebrospinal fluid in some cases.
Targeted therapy utilizes drugs that specifically target certain molecules involved in the growth and spread of brain tumors, offering a more precise and potentially less toxic treatment option.
