What are the symptoms of a brain tumour?
The symptoms of a brain tumour will depend upon which part of the brain is affected. The most common symptoms are caused by an increase in pressure in the skull (intracranial pressure) caused by the growth of a tumour in the brain.
Are headaches caused by a brain tumour?
Headaches are one of the main symptoms of a brain tumour, but of course there can be many reasons for having a headache. Headaches caused by a brain tumour tend to:
- Be severe and persistent
- Often worse in the morning
- Get worse over a number of days
- Give stabbing pains if you do anything that increases the pressure in your head, for example coughing, shouting, bending over or doing exercise.

Brain tumours that affect the pituitary gland
Because the pituitary gland has such varied functions, tumours in this area can be difficult to diagnose. Symptoms are often due to changes in the levels of the hormones that the gland produces and there is a range of reasons why those hormone levels may fluctuate, hence delaying the diagnosis of a tumour.
Symptoms caused by hormonal fluctuations include:
- Delayed puberty in children
- Changes in menstrual periods or early menopause in women
- Increased or decreased sexual drive
- Extreme growth spurts in both children and adults, particularly of either hands or feet
- Unexplained weight gain or loss, sometimes combined with a loss of appetite
- Extreme tiredness and/or listlessness
- Personality changes such as hostility, depression, anxiety
- Low blood pressure
- Loss of muscle mass in adults
- Easy bruising of the skin, often combined with muscle weakness
- Changes in the sense of smell
- Vision problems such as blurring, double vision, loss of peripheral vision
- Nausea and vomiting
- Diabetes insipidus, caused by problems with a hormone called vasopressin (AVP), commonly known as antidiuretic hormone (ADH). Symptoms are extreme thirst and/or excessive urination
Professional medical advice should be sought to check the cause of these symptoms as soon as possible, although they are also more commonly symptomatic of other illnesses or diseases.
However, if no definite alternative cause for your symptoms can be found and if you suspect something is really wrong, and if you’re experiencing a combination of these symptoms together or in succession, then insist that you or your family member gets referred to a neurologist (a brain and nervous system specialist) and an MRI scan. Early detection and treatment may avoid acute complications later on. Early detection and treatment may avoid acute complications later on.
