Chennai: Brain tumour has emerged as a type of cancer that affects a large population of youngsters mostly due to exposure to ionizing radiation.
Though a large number of brain tumours can be non-cancerous, the prevalence of brain tumour of both types is rising in the country. On World Brain Tumour Day, medicos discuss various factors associated with brain tumour.
Unnecessary growth of cells within a part of brain can lead to tumours namely, malignant and benign tumours. The incidence of brain tumour has been growing and statistics on childhood cancer reveal that brain tumour is commonest in girls and even in both sexes in adults in the country, though the data may vary for different states.
“Every year 40,000 to 50,000 people are diagnosed with brain tumour. There are 120 different types of brain tumour and they exhibit different symptoms. People who have been exposed to ionizing radiation for longer periods have an increased risk of brain tumour, especially among the youngsters,” said Dr Suresh Kumar, consultant neurologist, Fortis Malar.
After the central government introduced National Cancer Control Programme, various programmes have been launched to screen and diagnose brain tumour at an early stage, and a significant part of it emphasizes on providing palliative care in end stage.
“Genetic factors are also responsible for the incidence of brain tumours, and high dosage of X-rays is also dangerous and can be a risk factor for brain tumour. Some common symptoms are seizures, headaches, blurred vision, vomiting in morning, while the patient can also have difficulty in walking, speaking and sensation,” said senior neurologist N Dinesh.
Medicos usually suggest surgery, radiotherapy, chemotherapy, steroids and anti-seizure medication as few common treatments. However, the treatment can be individualistic based on the type, location, and stage of the tumour.
