Understanding the Link between Cancer Treatments and Hearing Loss

Cancer treatment can sometimes affect hearing as well as the condition being treated. Certain medicines, radiation near the head or neck, surgery and treatment-related complications may affect the ears, auditory nerves or balance system.

Changes can appear during care or later. Knowing what to watch for helps individuals report symptoms sooner, arrange suitable assessment, protect everyday communication and seek timely hearing support throughout treatment, recovery and follow-up care when needed.

Can Cancer and Its Treatments Affect Your Hearing?

Yes, cancer and hearing loss can sometimes be connected. Certain cancers, medicines, radiation or treatment-related complications may affect the ears or auditory system, leading to muffled hearing, ringing, buzzing, dizziness or balance changes during or after treatment. 

What Causes Hearing Changes during Cancer Treatment?

Medicines may affect inner-ear structures, radiation may involve nearby tissues, infections can disturb hearing, and surgery may affect auditory nerves.

Effects of Cancer on the Ear and Auditory System

Cancers affecting the head, neck, brain or nearby tissues may influence hearing and balance.

People may experience changes involving:

• Hearing pathways
• Sound transmission
• Balance-related structures

Early assessment can help identify and monitor these changes.

Treatment-Related Changes in Hearing

Some cancer treatments can affect the cochlea, auditory nerve or nearby tissues. A hearing test helps document changes.

People may notice:

• Less distinct sound
• Difficulty hearing higher sounds
• Ringing or unsteadiness

Which Cancer Treatments Are Linked to Hearing Loss?

Platinum-based chemotherapy and radiation involving the brain, head or neck are recognised hearing-related concerns. Surgery and some supportive medicines may also contribute.

Chemotherapy and Hearing Health

Certain platinum-based medicines may affect inner-ear structures. Chemotherapy-related hearing loss can vary between individuals and should be monitored during care.

Possible signs include:

• Reduced sound clarity
• Difficulty hearing higher-pitched sounds
• Ringing or buzzing

Hearing loss after chemotherapy should be professionally assessed.

Radiation Therapy and Hearing

Radiation near hearing structures may affect the cochlea or surrounding tissues.

Possible changes include:

• Reduced hearing
• Ear fullness
• Ringing or sound distortion

Some effects may appear later.

Other Cancer Medicines and Hearing Changes

Some antibiotics and supportive medicines used during cancer treatment may also influence hearing.

Individuals should:

• Report hearing changes promptly
• Mention tinnitus or dizziness
• Follow prescribed treatment
• Seek hearing assessment when advised

Any new symptoms should be discussed with the healthcare team.

What Types of Hearing Problems Can Occur during Cancer Treatment?

Symptoms may affect hearing sensitivity, sound quality, comfort or balance. The experience can vary considerably between individuals.

Hearing Loss or Muffled Hearing

Treatment-related hearing loss may make speech seem softer or unclear.

People may:

• Miss parts of conversations
• Struggle in background noise
• Increase television or phone volume

Tinnitus or Ringing in the Ears

Tinnitus may cause sounds without an external source and can become more noticeable in quiet settings.

People may experience:

• Ringing
• Buzzing
• Humming
• Sounds in one or both ears intermittently

Sound Sensitivity and Discomfort

Everyday sounds may feel sharper or less comfortable than before.

People may notice:

• Discomfort in noisy settings
• Irritation with ordinary sounds
• Greater listening fatigue

Balance and Dizziness Issues

Inner-ear effects may disturb balance. Severe or sudden dizziness needs medical attention.

Possible symptoms include:

• Unsteadiness
• Spinning sensations
• Difficulty changing position

What Are the Early Signs of Treatment-Related Hearing Loss?

These early changes can be easy to miss, especially when treatment already feels overwhelming. Early changes can be subtle.

Watch for:

• Asking for repetition more often
• Speech sounding muffled
• Difficulty following group conversations
• New ringing or buzzing
• Trouble hearing softer sounds

These changes are worth reporting even when they initially seem minor.

Why Should Hearing Be Monitored during Cancer Treatment?

Monitoring allows hearing to be compared over time. A baseline before potentially ototoxic treatment and follow-up testing can help identify changes earlier and provide useful information to the care team.

Importance of a Baseline Hearing Test

A baseline provides a useful reference before treatment.

It can:

• Record existing hearing ability
• Identify earlier difficulties
• Support later comparison

Regular Hearing Assessments during Treatment

Testing frequency should follow individual clinical advice.

Follow-up assessments may help:

• Compare hearing results
• Track new symptoms
• Plan appropriate hearing support

Can You Reduce the Risk of Hearing Damage during Cancer Treatment?

Individuals can attend recommended assessments, report symptoms promptly, discuss hearing aids where appropriate and avoid loud noise, particularly during treatments that may affect hearing.

Discuss Hearing-Related Side Effects with Your Doctor

Ask whether the planned treatment could affect hearing or balance.

Useful questions include:

• What symptoms should I report?
• Will I need hearing monitoring?
• Who should I contact if symptoms begin?

How Can Hearing Loss Affect Life after Cancer Treatment?

Hearing difficulty can affect much more than sound itself.

It may influence:

• Family conversations
• Workplace communication
• Social confidence
• Participation in group activities
• Enjoyment of television or music

How Can Hearing Loss Be Managed after Cancer Treatment?

Management depends on the type of hearing change, communication needs and overall health. Suitable approaches may include communication strategies, listening devices, rehabilitation or further medical evaluation.

Hearing Aids for Treatment-Related Hearing Loss

For suitable cases, hearing aids may support:

• Everyday conversations
• Phone or television listening
• Communication in group settings

Some people may also discuss AI hearing aids where advanced sound processing suits their hearing needs and listening preferences.

Professional Audiological Support

Audiologists can assess and monitor hearing changes. Support may include:

• Hearing assessment
• Device fitting and adjustments
• Communication guidance

You can book an appointment when hearing symptoms persist, worsen or begin affecting everyday communication.

When Should You See an Audiologist?

Professional evaluation is advisable when hearing or balance symptoms appear or worsen.

Seek support for:

• Persistent muffled hearing
• New ringing
• Difficulty understanding speech
• Dizziness or imbalance

Sudden hearing loss requires urgent medical attention.

Taking Care of Your Hearing during and after Cancer Treatment

Hearing awareness should continue through treatment and recovery.

Helpful steps include:

• Report new symptoms early
• Attend recommended assessments
• Protect the ears from excessive noise
• Follow professional hearing advice

Regular communication between the individual, oncology team and hearing-care professional can make changes easier to identify and manage.
