The most common and apparent symptoms are headache, vomiting, problem while walking and balancing, numbness in arms and legs changes in mood, personality, speech, vision etc. Other significant symptoms include severe headaches that worsen in the morning, nausea, seizures weakness in the face or hands and difficulty in body movements.
Types Of Brain Tumour
A brain tumour or cancer is an abnormal growth of cells in the brain, i.e. the Grey mater/or White mater/ & Meninges. A brain tumour can arise in any of the three parts and is classified into two main categories primary and secondary tumour. Primary tumours begin primarily within the brain tissue and can be either cancerous or benign (pure tumour), while the Secondary tumours are always malignant and arise from outside the brain. They are named as per the type of the cells or the part of the brain in which they appear.
PRIMARY TUMOURS: A few things you need to know about these types of tumours
- Primary tumour of the brain is of various types like Glioma or Astrocytoma, Ependymoma, Oligodendroglioma, Medulloblastoma, Germ cell tumour etc. Out of this, Glioma is the most common primary cancerous brain tumours. They are commonly seen in the general adult population, but lately, its occurrence has increased in young people too.
- Primary benign tumours are not cancerous and can be entirely treated after surgical removal. Various types of benign tumours are Meningioma, Pineal tumour, Schwannoma, Craniopharyngioma etc. Most common primary brain tumour seen in the adult female population is Meningioma.
SECONDARY TUMOURS: A few things you need to know about the secondary tumours
Secondary tumours are commonly seen in the older population. Here the cancer cells spread to the brain from cancer already present in the body affecting another organ. They are more common in occurrence than primary brain cancer.
Minimally Invasive Surgery For Brain Tumours (Treatment Of Brain Tumours)
- Unlike earlier times, brain tumours can be cured without undergoing severe surgeries. In comparison to conventional brain tumour surgeries which are almost open surgeries, endoscopic brain tumour surgery is the latest minimally invasive procedures providing ease of access to the treating surgeon and preserving the cosmetic appeal as well. Surgeons can have a real-time analysis of the brain as the endoscope enters the targeted location, allowing them to penetrate deep into the brain where conventional surgeries fail quickly.
- Being completely safe for the adjoining brain tissues; this procedure requires less hospitalisation and quicker recovery. This not only gives a better chance to the patient to live a remarkable functional life but also confirms the diagnosis of the tumour is cancerous or benign. Once the biopsied tumour confirms tumour as a malignant patient needs further treatment with chemotherapy and radiotherapy. Once treatment is complete patient requires physical and social rehabilitation to get back his healthy life by allowing him to perform the activities of his daily living as soon as possible.
