A brain tumour is a growth of abnormal cells in or near the brain. It can also happen in the nerves, the pituitary gland, the pineal gland and the membranes that cover the brain surface. Not all brain tumours are malignant. But even a benign brain tumour may be dangerous as it can press against healthy brain tissue and interfere with critical functions like movement, memory and speech.

Some of the initial symptoms include constant headaches, morning nausea, blurry or double vision, changes in balance and coordination, trouble holding focus, etc.

Initial warning signs to be mindful of

Stubborn headaches: Recurrent headaches are one of the most common early symptoms of a brain tumour. Such headaches, which often become more frequent over time, usually feel more intense in the morning and get worse with coughing, sneezing or sudden movement. If you are suffering from such obstinate headaches, please consult a doctor.
Blurred or double vision: If you have vision problems like blurred or double vision, or a sudden vision loss in one eye, it could be the manifestation of pressure building in the brain. Some tumours can impinge on the optic nerve, causing vision issues. Repeated changes in prescription for spectacles can also signal something amiss.
Nausea or vomiting: Baffling nausea or vomiting (not linked to tummy issues or pregnancy) can sometimes be precipitated by crushing pressure inside the skull. If it occurs in the morning and comes along with a headache, it’s all the more worrisome.
Seizures: A seizure could be a grave warning sign, since it is sometimes caused by an abnormal electrical activity in the brain, triggered by a tumour. Besides trembling, a seizure could lead to temporary confusion, staring spells or unusual sensations.
Problem with balance/coordination: Sometimes, a tumour in the cerebellum (the brain area controlling movement) might cause balance or hand-eye coordination problems.
Trouble with speech: If you find yourself often struggling to find the apt word or are slurring, it could be associated with brain tumours in regions controlling language. So, if you feel you are unable to communicate with clarity, seek immediate help.
Behaviour change: Brain tumours that affect the frontal lobe can change one’s mood or personality. The person could become easily irritable, introverted and generally altered from his/her core personality.
Cognitive decline: A brain tumour can lead to short-term memory loss, confusion or problem concentrating. An affected person can struggle to perform routine daily tasks and become forgetful.
Hearing issues: Tumours situated close to the auditory nerve can cause loss of hearing or a ringing sensation (tinnitus). One shouldn’t ignore this.
Exhaustion and weakness: Chronic fatigue could also be associated with brain tumours. Some might also feel weak or numb on one side, indicating pressure on certain areas of the brain controlling movement.
