Brain cancer warning - why you should never ignore feeling sleepy

Brain cancer is caused by cells multiplying in an abnormal way, according to the NHS.

Symptoms of the condition are caused as the tumour takes up space inside the skull.

The signs can develop over a period of time, and patients may not show any symptoms to begin with.

But, you should see a GP if you’re feeling persistently drowsy.

“Some symptoms of a brain tumour are very general and lots of other medical conditions can cause them,” said Cancer Research UK.

“It's unlikely to be a brain tumour, but always get your symptoms checked out.

“You might find you feel drowsy or you are sleeping more. You might be falling asleep during the day.”

The NHS added: “See your GP if you have the above symptoms, particularly if you have a severe and persistent headache.”

Other signs of brain cancer include persistent headaches and seizures.

You should also see a GP if you have progressive weakness, vision and speech problems, and paralysis on one side of the body.

Persistent nausea and vomiting may be signs of the deadly disease.

If your GP can’t identify a cause of the symptoms, they may refer you to a neurologist for further tests.

More than 9,000 people are diagnosed with brain tumours in the UK every year.

About half of all primary brain tumours are cancerous, the NHS said.

You’re more likely to develop the disease is you’re exposed to high levels of radiation.

Losing weight could help to prevent brain cancer, said Cancer Research UK.
