The brain is a body organ composed of nerve cells and supportive tissues such as glial cells and meninges. It has three major parts that control your activity such as breathing (brain stem), activity such as moving muscles to walk (cerebellum), and your senses such as sight, as well as our memory, emotions, thinking, and personality (cerebrum).
Primary brain tumours can be malignant (contain cancer cells) or benign (do not contain cancer cells).
A primary brain tumour is a tumour that starts in the brain tissue.
If a malignant tumour begins elsewhere in the body, it might transmit cancer cells that proliferate in the brain.
These are referred to as secondary tumours.
Tumors in the brain can develop at any age. The actual aetiology of brain tumours is unknown to researchers and clinicians. Ionizing radiation exposure and a family history of brain malignancies are risk factors.
The symptoms of brain tumours vary according to their size, nature, and location.
Headaches, numbness or tingling in the arms or legs, seizures, memory issues, mood and personality changes, balance and walking problems, nausea and vomiting, or changes in speech, vision, or hearing are the most prevalent symptoms.
Brain tumours are graded by grade by doctors (grade I, grade II, grade III, or grade IV -the most severe).
The grade is determined by the appearance of the cells under a microscope.
The higher the grade number, the more aberrant the cells appear, and the tumour typically behaves aggressively.
