Common side effects

Mouth problems

Some head and neck cancer treatments can cause mouth sores, ulcers and saliva changes. These problems can make eating difficult, but there are ways to manage them.

Mouth sores and ulcers

Mouth sores and ulcers are a common side effect of chemotherapy and radiation therapy. This is known as oral mucositis. The sores can form on any soft tissue in your mouth and make eating, swallowing and talking difficult. This is usually short term and goes away as you recover from treatment. Your doctor can give you medicines to reduce the pain when you eat, drink or speak. 

Your speech pathologist and dietitian can suggest foods to reduce discomfort. You may need to choose softer foods and nourishing fluids. If you are unable to eat and drink enough to stay well nourished, you may need a feeding tube to support you during treatment and recovery.

Dry mouth and saliva changes

Radiation therapy to the head or neck area and surgery that affects the salivary glands can reduce the amount of saliva in your mouth, make your mouth dry or make your saliva thick and sticky. This is known as xerostomia and it is often long-lasting.

Xerostomia can make chewing, swallowing and talking difficult. A dry mouth can also make it harder to keep your teeth and mouth clean, which can increase the risk of tooth decay.

 

Fatigue

Fatigue for people with cancer is different from tiredness, as it may not go away with rest or sleep. It is common to feel very tired during or after treatment, and you may lack the energy to carry out day-to-day activities. For some people, fatigue continues for months or years after treatment ends.

Taste, smell and appetite changes

Having treatments to the head, neck and mouth area may affect your sense of taste and smell.

Some treatments can change the way the salivary glands work and affect the flavour of food. It is important to try to keep eating well so your body gets enough nourishment. Try experimenting with different textures, temperatures and presentations to make food more enjoyable. You could also try to do distract yourself by watching TV or reading a book while eating.

It can take several months for your sense of taste and smell to return to normal, and this may affect your appetite. A speech pathologist may be able to teach you a technique to help you regain your ability to smell. In some cases, taste changes may be permanent.

Swallowing difficulties

Chewing and swallowing involves your lips, teeth, tongue and the muscles in your mouth, jaw and throat working together. Many people with a head and neck cancer have difficulty swallowing (dysphagia) before, during or after treatment, which may be short term or long term.

Being able to swallow is important to ensure you are eating and drinking enough. Signs that swallowing is difficult include:

  • taking longer to chew and swallow
  • taking longer to eat a meal than your family and friends
  • coughing or choking while eating or drinking
  • food sticking in your mouth or throat
  • pain when swallowing.

Treatment that may cause swallowing difficulties

  • Surgery to the jaw, mouth or throat areas – this may make chewing and swallowing difficult because tissue has been removed or reconstructed, or because the surgery has caused dry mouth.
  • Surgery to the larynx or pharynx – surgery to the larynx or pharynx may cause food to go down the wrong way into the lungs. This is known as aspiration and signs include coughing during or after swallowing, increased shortness of breath during or after a meal and recurrent chest infections.
  • Radiation therapy – this can cause dry mouth, pain, and changes to the strength of the muscles and nerves used in swallowing. These effects could be worse if you have chemotherapy at the same time as radiation therapy (chemoradiation).

Using a feeding tube

After surgery or radiation therapy, a feeding tube may be inserted to help you get the nutrition you need while your throat heals.

This tube is usually temporary (inserted through a nostril, then down the throat and oesophagus into the stomach), but sometimes it is long-term or permanent (inserted through an opening on your abdomen into the stomach).

A feeding tube can help ensure you maintain your weight and energy. If you can’t swallow medicines, check with your treating team about whether these can also be given through the feeding tube. They will also show you how to care for the tube. 

Having a feeding tube inserted is a major change, and it is common to have a lot of questions. Talking to a dietitian or nurse can help, and a psychologist or counsellor can provide emotional support and suggest ways to cope.

How to eat when swallowing is difficult

  • See a speech pathologist for ways to change your chewing and swallowing action to help reduce discomfort or food going down the wrong way (aspiration). They can also show you swallowing exercises, ways to change your posture and how to adjust the consistency of food to make it easier to swallow.
  • Continue to eat and drink whenever possible throughout your treatment to keep your swallowing muscles moving and working. This will reduce the likelihood of long-term swallowing problems.
  • Ask your doctor to recommend medicines that relieve discomfort when swallowing. Some of these medicines come as mouth rinses.
  • Talk to a dietitian to make sure you are getting enough nutritious food and drink.
  • See the recipes in two free online books from Griffith University – From Treatment to Table and Beyond the Blender: Dysphagia Made Easy.

 

Malnutrition and weight loss

Some side effects may make eating difficult, which can cause you to lose weight. Even a small drop in your weight, especially over a short period of time, may put you at risk of malnutrition.

Unplanned weight loss and malnutrition can affect how you respond to treatment, and side effects may be more severe and your recovery slower. You can be malnourished even if you are overweight.

Changes to speech

The ability to talk can be affected by surgery and radiation therapy. This may be because of side effects such as swelling and irritation, because of a tracheostomy or laryngectomy, or because other structures have been removed.

You may find it hard to speak clearly or notice that your speech is slurred, or you may find your voice has changed. The extent of any changes will vary depending on the location of the cancer, how advanced it was, and the treatment you had. 

How to manage speech changes 

  • Talking will take time and practice – it’s natural to feel distressed, frustrated and angry at times. You will need to get used to the way your new voice sounds.
  • Try non-verbal ways to communicate – gesture, point, nod, smile, mouth words, write things down or ring a bell to call people.
  • Use a computer, tablet, mobile phone or notebook to write and send notes.
  • Work with a speech pathologist to improve your speech and learn ways to communicate with family and friends. They may give you some exercises to improve the strength and range of motion of the lips, tongue, jaw and larynx.
  • Encourage family and friends to be honest if they don’t understand you and to learn new ways to communicate with you. Ask them not to avoid conversation even if it is difficult at first. They may need to be patient and give you time to respond.
  • Speak to a counsellor or psychologist if you are finding it difficult to cope with speech changes.
  • The National Relay Service can help you make phone calls.

 

Breathing changes

Some people treated for head and neck cancer need a tracheostomy. This is an alternative airway created in the front of the neck so they can keep breathing freely. 

Having a tracheostomy

A small cut in the lower neck allows a tube to be inserted into the windpipe. This can be used for breathing during and after surgery when the mouth or throat becomes swollen. It is usually removed within one week of surgery once the swelling has gone down. In some cases, a tracheostomy is needed for longer or even during radiation therapy, but this is uncommon.

The thought of a tracheostomy may be confronting and scary – talk to your treatment team about how you are feeling and ask them to explain why it is needed. Initially you may not be able to speak, but you will be supported by your treatment team, especially the speech pathologist and physiotherapist.

Once the tracheostomy tube is removed, the hole in your neck normally closes within days. During this time, your voice may be weak and breathy, but will return to normal when the hole closes.

Having a laryngectomy

If you have a total laryngectomy, a permanent stoma or breathing hole will be created in your lower neck at the time of the surgery. This will be discussed with you before surgery so you know exactly what to expect, including how you will speak again. If you need a permanent stoma, the speech pathologist and nurses will teach you how to look after it. 

If the larynx (voice box) is removed, there are various ways to speak:

  • Voice prosthesis speech – the surgeon makes an opening between your trachea and oesophagus. A small voice prosthesis (or valve) is inserted to direct air from your trachea to the oesophagus. This will allow you to speak clearly in a low-pitched, throaty voice.
  • Mechanical speech – a battery-powered device (electrolarynx) is used to create a mechanical voice. The device is held against the neck or cheek or placed inside the mouth. You press a button on the device to make a vibrating sound.
  • Oesophageal speech – you swallow air and force it up through your oesophagus to produce a low-pitched sound. This method can be difficult and you will need training.

Living with a tracheostomy or stoma

Having a tracheostomy or stoma is a big change and takes some getting used to. Your specialist, nurse or speech pathologist can explain ways to manage the following concerns:

  • caring for the tube or stoma – you will be shown you how to clean and care for the tracheostomy tube or stoma.
  • coping with dry air – the air you breathe will be much drier since it no longer passes through your nose and mouth, which normally moistens and warms the air. This can cause irritation, coughing and extra mucus coming out of the tracheostomy tube or stoma. There are products available that cover the stoma or attach to the tracheostomy tube to provide heat and moisture for the windpipe.
  • swimming and bathing – you will need to use a special stoma cover to avoid water getting into the windpipe, even in the shower. If you have a laryngectomy stoma, you may not be able to go swimming.

 

Pain, numbness and stiffness

Ongoing pain, numbness and restricted movement in the head and neck area, such as not being able to fully open the mouth or jaw (trismus), may lead to distress, low mood, fatigue or reduced appetite. Speak to your treatment team about ways to manage pain and regain movement.

If you have lymph nodes removed from your neck, you may have some nerve damage that makes your neck feel tight and numb, and your shoulders feel stiff and painful. Some chemotherapy drugs can cause nerve damage that leads to tingling, pain or numbness in the hands and feet. Nerve damage is often temporary but can be permanent.

Other physical changes

Changes to appearance

Many types of surgery for head and neck cancer will cause temporary or permanent changes to the way you look. For example:

  • Weight loss – it is common to lose weight during treatment and it can be hard to put it back on.
  • Feeding tube – people who need a feeding tube or tracheostomy tube may feel self-conscious.
  • Scars – improved surgical methods mean that most people won’t have major scarring. Surgeons will try to hide scars in skin creases in the neck or on the face, and the scars usually fade over time. Scars from radiation therapy may change the colour or texture of the skin.
  • Face – in some cases, removing the cancer means removing an eye or part of the jaw, nose, ear or skin. Some people have reconstructive surgery using tissue from another part of the body, while others may have a prosthesis.
  • Jaw and teeth – for certain cancers, your surgeon will need to cut through your jaw (mandibulotomy) and reconstruct it with a plate. This involves a cut through your chin and lip, and the scars will be noticeable for some time. If you have lost teeth due to cancer treatment, you may be able to have further surgery to replace or reconstruct them.
  • Swelling – surgery or radiation therapy can damage lymph nodes, and this can cause swelling known as lymphoedema.

Give yourself time to get used to any physical changes. Some changes may be temporary and improve with time. Talk about how you are feeling with someone, such as a family member, friend, social worker, occupational therapist or psychologist.

Impact on sexuality and intimacy

Head and neck cancer can affect your sexuality in both emotional and physical ways. Reduced interest in sex (low libido) is common and if your appearance has changed, you may worry that you are less sexually attractive or you may be grieving the loss of how you used to look.

Treatment for head and neck cancer sometimes causes side effects such as dry mouth, bad breath, thick and sticky saliva, poor tongue and lip movement, facial palsy, scars, or a stiff neck and jaw. These side effects can all make kissing and oral sex difficult or less pleasant.

Surgery to the mouth may reduce feeling in the tongue or lips. This can affect the enjoyment and stimulation from kissing, but feeling should return in 12–18 months. If your speech is altered, this may affect your self‑esteem and ability to express yourself during sex.

You or your partner may be afraid of having sex if the cancer was HPV-related. Talk to your doctors if you are concerned about the risk of passing on HPV to a long-term or new partner.

Some people choose to express their feelings in other ways, such as cuddling, holding hands or touching cheek-to-cheek. You may wish to talk to a psychologist or sexual health professional, by yourself or with a partner, to help you find ways to adapt to any sexual changes.

Vision changes

If the cancer is in your eye socket, the surgeon may have to remove your eye (orbital exenteration). The empty eye socket will be replaced by a sphere of tissue from another part of your body. This keeps the structure of the eye socket.

Later you can be fitted for an artificial eye, which is painted to look like your remaining eye and surrounding tissue. The eye is like a large contact lens that fits over the new tissue in the eye socket.

You will still be able to see with your remaining eye, but your depth perception and peripheral vision won’t be as good. You will usually still be able to drive and play sport, but it may take time to get used to the changes. Before you start driving again, tell your driver licensing authority about the changes in your vision, as there may be restrictions you have to follow.

Hearing loss

Some treatments for head and neck cancer can affect your hearing. Certain chemotherapy drugs can cause hearing loss. Sometimes the first sign of this is ringing in the ears (tinnitus), so let your doctors know if you experience this.

Radiation therapy can damage the internal structure of the ear, causing fluid to build up behind the eardrums and leading to loss of hearing. Some surgeries to the head and neck, especially for nasopharyngeal cancer, can cause temporary or permanent hearing loss.

Ask your treatment team whether you are at risk of hearing loss and if you should have your hearing tested after treatment ends.

Lymphoedema

If lymph nodes have been removed in a neck dissection or damaged by radiation therapy, it may prevent lymph fluid from draining properly. The fluid can build up and cause swelling in the neck, face and throat. This is known as lymphoedema. It can be temporary or permanent and may change your appearance.

People who have had surgery followed by radiation therapy to the neck are more at risk, especially if both sides of the neck are treated, as well as those who have had a lot of lymph nodes removed. Symptoms of lymphoedema are easier to manage if the condition is treated early.

Sometimes the swelling and other signs of lymphoedema can take months or years to develop, although some people who are at risk never develop the condition. 

 

Life after treatment

After treatment ends, you will have regular appointments to monitor your health, manage any long-term side effects and check that the cancer hasn’t come back or spread. You may have blood tests and imaging scans, as well as physical and visual examinations of your head and neck.

You will usually continue to have check-ups for five years, and will receive continued support from a speech pathologist, dietitian, occupational therapist, physiotherapist, psychologist and social worker if you need it. You may also be asked to see your dentist regularly.

For some people, head and neck cancer does come back after treatment (recurrence). Sometimes this will be another cancer of the head and neck, but it can also be the original cancer that has spread to another part of the body.

The treatments you are offered will vary depending on your previous treatments and it is important that you are reviewed by an experienced multidisciplinary team.
