screening for throat

Overview

Throat cancer screening looks for early signs of cancer in the throat before symptoms appear. It is not a regular test for everyone, but may be offered to people who have a higher risk, such as heavy smokers or heavy drinkers.

Throat cancer is uncommon compared to many other cancers. But certain lifestyle factors, like smoking and alcohol use, can increase the risk.

It can affect anyone, but it is more common in men and people over 50. People who use tobacco or drink a lot of alcohol are at higher risk.

Symptoms

Common symptoms

• a sore throat that does not go away
• trouble or pain when swallowing
• a hoarse voice lasting more than a few weeks
• a lump in the neck
• ear pain on one side

Symptoms in children

• Throat cancer is very rare in children. However, children can have voice changes, swallowing problems, or a lump in the neck. These are often due to non-cancerous causes, but it is important to see a doctor.

Symptoms in older adults

• Older adults may notice persistent hoarseness, difficulty swallowing, weight loss without trying, or a new lump in the neck. These symptoms should be checked by a doctor.

Causes

Main causes

• The exact cause is often not known. Most throat cancers are linked to tobacco and alcohol use.
• Infection with a virus called HPV (human papillomavirus), which can be passed through skin-to-skin contact.
• A condition called reflux, where stomach acid comes back into the throat, may increase risk.

Risk factors

• smoking or chewing tobacco
• drinking alcohol heavily
• being infected with HPV
• a diet low in fruits and vegetables
• being male and over 50

When to see a doctor

See a doctor urgently if:

• If you have trouble breathing, coughing up blood, or choking, call your local emergency number right away.

Book a routine appointment if:

• See a doctor if you have a hoarse voice, sore throat, swallowing problems, or a neck lump that lasts more than three weeks.

Diagnosis

To check for throat problems, a doctor will ask about your symptoms and examine your throat, neck, and mouth. They may use a small angled mirror or a thin, flexible tube with a camera, called an endoscope, to look inside your throat.

Tests that may be done

• a physical exam of your neck
• a nasendoscopy — a thin tube passed through the nose
• a biopsy — a tiny sample of tissue taken from the throat
• imaging scans, such as CT or MRI, if needed

What to expect at your appointment

Screening or assessment usually happens in an outpatient clinic. The doctor may use a spray to numb your throat. It can feel uncomfortable but should not be painful. If a suspicious area is found, a biopsy can tell whether it is cancer.

Treatment

Treatment for throat cancer depends on the type, stage, and location. It may include surgery, radiation therapy, chemotherapy, or a combination. Your healthcare team will explain your options and support you.

Self-care at home

• stop smoking and limit alcohol
• rest your voice and avoid shouting
• eat soft, easy-to-swallow foods
• tell your doctor about any new symptoms

Medical treatments

Medical treatments are planned by a specialist team. They may recommend radiation therapy to destroy cancer cells, chemotherapy to shrink tumours, or targeted therapies that attack cancer cell changes. Surgery may also be an option. The doctor will discuss what is best for you.

When is surgery considered?

Surgery may be used to remove cancerous tissue. In some cases, part of the throat or voice box may need to be removed. This can affect speaking or swallowing, and rehabilitation will be offered.

Living with this condition

Living after treatment may involve regular check-ups. Some people need help with eating, speaking, or managing side effects. Ask your care team about speech therapy and nutrition support.

Lifestyle tips

• join a support group for throat cancer survivors
• stay active as much as your energy allows
• tell friends and family how they can help
• keep a folder of your appointments and test results

Diet and exercise

Eating may be difficult during treatment. A dietitian can suggest soft or liquid foods that are high in protein. Gentle exercise, like walking, can help your energy levels and mood. Always check with your doctor first.

Mental health and emotional wellbeing

A cancer diagnosis can be stressful and may cause anxiety or depression. It is normal to feel worried. Talk to your nurse or doctor about counselling. If you feel very low, seek support as soon as possible.

Prevention

You can lower your risk by not using tobacco, limiting alcohol, and getting the HPV vaccine. Eating a diet rich in fruits and vegetables may also help.

Vaccines

An HPV vaccine can protect against the types of HPV that cause throat cancer. It is most effective when given before exposure to the virus. Ask your healthcare provider about the vaccine.

Screening programmes

There is no national screening programme for throat cancer for the general population. If you are at higher risk, your doctor may recommend regular checks. Talk to your clinician about your personal risk.

Complications

If left untreated

• If throat cancer is left untreated, it can grow and spread to lymph nodes or other parts of the body.
• It can cause severe trouble swallowing, making it hard to eat and drink.
• It can press on the airway and cause breathing difficulties.

Long-term outlook

Many throat cancers are treatable, especially when caught early. Your outlook depends on the type, location, and stage at diagnosis. Even for advanced stages, treatment can control the disease and maintain quality of life. Your care team will support you.
