EACH year around 12,300 cases of brain cancer are diagnosed in the UK, Cancer Research UK states.
This presents in the form of a brain tumour, which can cause a host of different symptoms, depending on their position.
Common signs include headaches, feeling sick or seizures.
But experts at Cancer Research UK said that there is one symptom that you can actually hear.
This would be due to a temporal lobe tumour, which the experts said may cause you to hear voices in your head.
They also explained that depending on the position of the tumour, you might struggle with how you process and store memories.
They added that you might also suffer from short term memory loss and difficulty hearing and speaking.
When it comes to the main symptoms, the experts delved into exactly what they will feel like.
If you have a brain tumour, it will likely press on your skull, due to the fact that there is only a limited amount of space for the organ to take up.
If the tumour is growing, the experts said this will increase the pressure inside the skull.
This is commonly referred to as raised intracranial pressure and it may cause the below six issues.
Medics at the charity said that this is one of the most common symptoms of a brain tumour, but added that if you just have a headache then it’s unlikely it’s down to cancer.
They added that if you have headaches combined with feeling or being sick, that wake you up in the night or if you have eye issues such as flashing lights or blind spots – then you should see your GP.
If you didn’t have headaches before and if they have become steadily worse over a period of weeks and months then you should also visit your doctor.
Figures from the charity show that seizures or fits occur in eight out of every ten people who have a brain tumour.
Guidance states: “You might have some jerking or twitching of your hands, arms or legs. Or your seizure might affect your whole body.
“Having a seizure is very frightening. Different illnesses can cause seizures and it is important that you see your doctor immediately or go to A&E if you have one.”
3. Feeling or being sick
Sickness that comes on when you move suddenly is another sign to look out for.
However, it’s unlikely that this will be your only symptom, and this will usually go hand-in-hand with headaches, weakness and problems with your eyes.
4. Drowsiness or loss of consciousness
The experts explained that you might experience drowsiness or loss of consciousness due to raised intracranial pressure which can lower the blood supply to the brain.
They added that this can be frightening for you and those around you.
5. Problems with your eyes
If you have a brain tumour, you might find that your eyesight is getting worse or that glasses aren’t helping.
“You might lose the ability to see out of the corner of your eyes, making you bump into cars or objects on your left or right side,” guidance states.
You could also struggle with blurred vision, floating shapes and tunnel vision, experts said.
6. Personality changes
One other thing to look out for, the guidance states, is changes in personality.
You or those around you might notice that you have become confused or you may struggle to think normally.
As well as the main symptoms, if you have a frontal lobe tumour you may experience issues with walking, problems with sight and speech, loss of smell or weakness on one side of the body.
If you have a parietal lobe tumour, you could have problems with reading or writing, difficulty speaking and understanding and you may also experience loss of feeling in one part of the body, the experts added.
It’s important that if you are worried about any of your symptoms, then you see your GP.
In the event of an emergency, always call 999.
