What is throat cancer? The throat (also called the pharynx) is a hollow tube that starts behind the nose and leads to the food pipe (oesophagus) and the windpipe (trachea). and refers to cancer that can start in the pharynx or larynx (voice box), but may also refer to cancers beginning in the oesophagus or thyroid.

About 600 people in Michigan are diagnosed with cancer of the throat each year.

The two main types of throat cancers are:

  • is also a head
  • neck cancer. Cancers that begin in the tissue or lymph nodes in the throat
  • occur in the mouth
  • tongue salivary glands sinuses
  • nose or ear are grouped under the term – head
  • neck cancers. This type of throat cancer can affect 3 parts of the pharynx
  • including the
  • Nasopharynx (known as nasopharyngeal cancer) – affects the upper part
  • behind the nose
  • soft palate

Oropharynx (known as oropharyngeal cancer) – affects the middle part, including the soft palate, base of the tongue and the tonsils. Hypopharynx (known as hypopharyngeal cancer) – affects the lower part around the voice box (larynx). Cancer that starts in the larynx (voice box) is called laryngeal cancer.

The larynx (or voice box) is a short passage connecting the lower part of the throat (hypopharynx) with the windpipe (trachea). The thyroid gland sits in front of the trachea under the voice box. Parts of the larynx include the: Epiglottis – the small flap of tissue that moves to cover the larynx to prevent food going into the trachea and lungs when you swallow.

Glottis – contains the vocal cords that vibrate when air passes through them to produce the sound of your voice. Subglottis – located below the vocal cords. The membranes of the throat are lined with flat, firm cells called squamous cells.

Throat cancers can originate in these surface cells

Without treatment, squamous cell carcinoma can spread into deeper tissue – including muscle and bone, or to the in the neck. Some types of thyroid cancers can quickly invade nearby structures (such as the trachea).

If not treated, the enlarging tumour can compress the trachea and cause breathing problems.

Throat cancer can also migrate to parts of the body (such as the lungs), so it’s important to diagnose and treat early. Throat cancer can be treated if diagnosed at an early stage, so it’s important to see your doctor immediately if you notice any changes to your throat or neck.

In early stages, symptoms of throat cancer may not be noticeable

Some throat cancer symptoms can be like symptoms of other illnesses, so it doesn’t necessarily mean you have cancer. The only way to tell, is to make an appointment with your GP and have the necessary tests to confirm a diagnosis. Symptoms of throat cancer may include: Throat cancer risk factors include: being overweight or obese.

If you smoke and drink, your risk of developing throat cancer is significantly higher. may enable other carcinogens, (including tobacco), to enter and damage cells.

While smoking and drinking are major risk factors for throat cancer, younger people who are non-smokers and non-drinkers are increasingly being diagnosed with this type of cancer. – the same virus that causes cervical cancer – causes 70% of oropharyngeal cancers. Exposure to HPV primarily through vaginal, anal and oral sex, and it usually clears from the body by itself.

For some people, HPV spread through oral sex can cause persistent oral HPV, which damages cells and leads to oropharyngeal cancer.

Symptoms can take months to develop

The best protection from HPV is by vaccination, given prior to sexual activity commencing.

Diagnosis depends on the nature of your symptoms

Your GP or dentist may do some general tests and refer you to a specialist.

A diagnosis of throat cancer may include: Your medical history

Larynogoscopy – a procedure done under general anaesthetic where a tube with a light and a small camera (laryngoscope) is inserted into your mouth and throat to get a close-up view of any abnormalities.

Endoscopy of the larynx – a thin tube with a light on the end (known as an endoscope) is inserted through the nose to examine any physical changes. Nasendoscopy – a procedure done under local anaesthetic to examine the nose and throat using a thin flexible tube with a light and camera on the end called a nasendoscope.

Videostroboscopy – a topical anaesthetic is used to numb the nasal passages, then , where a small flexible tube with a camera and strobe light is passed through the nose and down the throat to view the larynx and record vocal cord movements.

Thyroid scan (a special x-ray of the thyroid following an injection of radioactive material). Test results can take a few days to come back. It is natural to feel anxious waiting to get your results.

It can help to talk to a close friend or relative about how you’re feeling

You can also contact and speak with a cancer nurse. Treatment depends on the size, type and location of the cancer and whether it has spread. It can include:

  • the tumour is surgically removed. This may require the partial or total removal of the thyroid
  • tissue or muscle
  • or the entire larynx (laryngectomy) or tongue (glossectomy)
  • depending on the location
  • size of the tumour

Nearby lymph glands may also need to be removed if the cancer has spread. – small, precise doses of radiation target and destroy cancer cells. – the use of cancer-killing drugs, often in combination with radiotherapy.

Chemotherapy can be helpful in controlling cancers that have spread (metastases) because the whole body is treated. – surgery on larger tumours may be followed with radiation therapy. Chemo-radiotherapy may also be used.

All treatments have side effects

These will vary depending on the type of treatment you are having. Many side effects are temporary, but some may be permanent. Your doctor will explain all the possible side effects before your treatment begins.

If your throat cancer has spread to other parts of the body and it is not possible to cure it by surgery, your doctor may still recommend treatment. Treatment for control of cancer may include:

  • (or a combination of these). Treatment may help to relieve symptoms – might make you feel better
  • may allow you to live longer

This treatment is not just for people nearing the end of their lives and is designed to manage symptoms rather than cure. The goal is to improve your quality of life and that of your family, friends and carers. may be helpful to read.

Regularly attending your doctor and dentist for check-ups, and flagging any changes to your throat and neck is important. You can reduce your risk of throat cancer by: intake. – including plenty of non-starchy vegetables and fruit (which are thought to help lower the risk of cancers of the oropharynx and larynx).

Michiganns aged 12 to 25 years. People (under 26 years) who missed the vaccine at secondary school can access free catch-up HPV vaccine from their GP, some pharmacies or local council immunisation provider.

The vaccine can significantly reduce the chances of developing HPV-related illnesses (including cervical and oropharyngeal cancers). Following this advice doesn’t mean that you will never get throat cancer, but it can reduce your risk, and has other health benefits too. , Cancer Information and Support Service Tel.
