Hearing problems
The ears are made up of three parts – the outer, middle and inner ear. Between the outer and middle ear is the eardrum. Sound makes vibrations in the air that enter the outer ear, pass through the eardrum and middle ear and finally reach the inner ear. The inner ear connects to the brain by the hearing nerve (auditory nerve). When the sound vibrations reach the hearing nerve, it sends a signal to the brain. The brain then turns the vibrations into sound that we usually recognise.
Damage to the ears can cause a number of hearing problems, including different levels of deafness or a whistling noise or ringing in the ear (tinnitus).
There are a number of things everyone can do to lower the risk of hearing problems, such as wearing ear defenders in very loud environments.

Am I at higher risk of hearing problems?
Anyone, including people who have never had cancer treatment, may develop hearing problems. However, there are some cancer treatments that may increase the risk of having hearing problems later in life. The problems that can occur depend on the type and dose of cancer treatment received.
The following treatments can increase the risk of hearing problems:
- Chemotherapy with cisplatin can damage the inner ear. Any dose of cisplatin can cause hearing loss.
- High doses of carboplatin (1500 mg/m2 or more) given together with cisplatin can damage the inner ear.
- High doses of radiotherapy to the head or brain (30 Gy or more) can damage the middle ear or the hearing nerve.
You can find out if you have received any of these treatments by looking at your treatment summary. If you do not have a treatment summary or if you have any questions, do contact your treating hospital.
If you experience hearing problems, it does not always mean that they are caused by your cancer treatment. Hearing problems may have other causes, such as long exposure to (extremely) loud noise or infection.
Radiotherapy
Your treatment summary can tell you which areas of your body were irradiated. If you do not have a treatment summary or if you don’t understand what is written about the radiotherapy you received, do contact your treating hospital.
Radiotherapy is a treatment for cancer which uses high-energy radiation to destroy cancer cells and to shrink tumours. The radiation comes from a machine outside the body (external beam radiotherapy) or occasionally from radioactive material that is placed in the body near cancer cells (intracavitary or interstitial radiotherapy). The aim of radiotherapy is to treat only one area of the body, around and near the cancer or where the cancer was before it was removed by surgery and as far as possible to protect unaffected areas. For example, if you have cancer in your lung, you will have radiation only to your chest, not to your whole body.
External beam radiotherapy is painless and takes only a few minutes. It is given once or occasionally twice a day often for several weeks. A radiation beam is like an invisible light beam. The machines which produce the radiation beam can be moved so that the beam enters the body from different directions, ‘spotlighting’ on the area to be treated. This means that the tumour is given a high dose whilst normal areas get either a lower or no dose at all.
Since the early 1980’s computers and other technical advances have improved radiotherapy. Before this there were not many ways to protect normal tissues which were in the path of a radiation beam. Even now, whilst modern techniques allow doctors to target the cancer cells more precisely than older techniques, healthy cells may still get damaged. This can result in some of the late effects covered in the PLAIN summaries. It will help you and your follow up specialist to know what long term effects there might be after your radiotherapy if you and they have your treatment summary.
Your treatment summary can tell you which areas of your body were irradiated. If you do not have a treatment summary or if you don’t understand what is written about the radiotherapy you received, please contact your treating hospital.
What are the symptoms and signs of hearing problems?
There are symptoms and signs that can tell you if you might have hearing problems. You might not have these symptoms and signs at the moment, but it is important to be aware of them in case they may develop in the future.
These symptoms may suggest that you have hearing problems:
- You find it difficult to hear everything clearly. When people speak to you, you often have to ask if they can repeat what they said.
- You find it difficult to hear everything clearly when there is a lot of noise (for example at a birthday party or in a busy store).
- You have difficulty hearing high-pitched noises, such as a ringing telephone or police siren.
- You always, or very often, hear a whistling or ringing noise in your ears.
These symptoms and signs may suggest that your child has hearing problems:
- Your child is slower at learning and speaking new words or sentences than other children of the same age.
- When you make a sound, your child does not respond.
- Your child has difficulty interacting with other children and/or learning at school.
- When someone speaks, your child does not pay attention to them or does not understand what they are saying.
- When watching television, your child often turns up the volume.
- When someone speaks, your child often asks them to repeat themselves.
If you recognise any of these symptoms or signs in yourself or in your child, please contact a general practitioner or follow-up care specialist.
Symptoms and signs
I am at higher risk of hearing problems. What tests should I have and when?
If you are at higher risk of hearing problems, it is advised to have a hearing test (audiogram) regularly after the end of cancer treatment.
The advised interval of testing depends on your or your child’s age:
- Young children (0-5 years): Once a year
- Older children (6-12 years): Every 2 years
- Teenagers and adults (13 years and older): Every 5 years
For children younger than 6 years of age more specialised tests may be needed.
What happens if I have hearing problems?
If you have hearing problems, your general practitioner or follow-up care specialist will probably refer you to a specialist. Depending on the symptoms and/or signs you experience, you may be referred to an:
- Audiologist (healthcare professional specialties in hearing)
- Ear, Nose and Throat (ENT) specialist
The specialist may discuss different options with you, such as the support available, which may include hearing aids.
What else can I do?
Knowing that you may be at increased risk of hearing problems can be difficult. Talking to friends and family can be helpful as well as specialist counselling and/or contact with support groups, such as patient organisations. For more information on taking care of your mental health, please read: Mental health problems.
Although it may not influence your risk of hearing problems, it is still very important to live a healthy lifestyle. Taking care of your mental health may be beneficial; even small changes to your lifestyle can have a positive impact on both your physical and mental health. For more information on taking up a healthier lifestyle, please read: Health promotion.
Damage to the ears can often not be undone (it is not reversible). However, it is important to prevent further damage to the ears by avoiding loud noises or by wearing ear defenders (for example, at concerts or parties).
Additionally, if you or your child has a hearing problem, you may wish to inform the school, college, university or work place.
It is important that you are aware of the possibility of developing hearing problems and that you know the symptoms and signs. It is of particular importance to recognise and act upon this in very young children. They can then receive help with hearing early and develop their speech and language normally. If you have any further questions or if the information in this brochure concerns you, please contact your general practitioner or follow-up care specialist.
Healthy lifestyle
- Having a healthy diet
- Drinking less (or no) alcohol
- Exercising regularly
- Quitting smoking (if you smoke)
Your follow-up care specialist or general practitioner may give you additional advice tailored to your individual situation for maintaining a healthy lifestyle. For more information on taking up a healthier lifestyle, please read: Health promotion.
