Throat cancer: Symptoms, causes, and treatment
Share the article

The fact that so many disorders have similar symptoms is one of the problems in medicine. A simple cough or sore throat normally doesn’t cause too much concern. They typically disappear on their own. However, occasionally they are signs of a more severe condition, such as throat cancer. The structures that allow you to swallow, speak, and breathe are where throat malignancies develop.

The throat itself—the tube that begins behind your nose and finishes in your neck—is where about half of these malignancies develop. Another name for it is “pharynx.” The “larynx,” or voice box, is where the rest begins. These illnesses frequently spread swiftly. The best chance of beating them and maintaining a high quality of life is to get treated as soon as possible.

Symptoms of throat cancer

You might have:

  • voice modifications such as hoarseness, cracking, or difficulty speaking clearly
  • breathing or swallowing issues.
  • having the sensation that something is in your throat
  • An earache that won’t go away, a bloody cough, or a sore throat
  • Headache
  • Having neck or ear pain
  • A neck lump or persistent pain.
  • Unaccounted-for weight loss

If any symptoms persist for more than a few weeks, make an appointment with your doctor immediately.

However, bear in mind that numerous illnesses that aren’t cancer share identical symptoms.

Risk Factors

When some of the genes in your throat’s cells mutate, you can develop throat cancer. Although doctors don’t know what causes this transformation, the following factors can increase the likelihood:

  • Smoking cigarettes for a long time – The most prominent risk factors for all head and neck cancers, including throat cancer, are smoking and chewing tobacco.
  • Drinking often entails consuming more than two drinks of alcohol per day for men and more than one drink per day for women. In addition, if you smoke and drink, your risk is increased even more.
  • HPV – Tongue and tonsil cancers are among the cancers of the back of the throat associated with the human papillomavirus.

Other risk factors are:

  • Gender – Men are five times more likely than women to contract it.
  • Age – Most diagnoses occur beyond age 65.
  • Race – Men of African American descent are most in danger.
  • Chemotherapy exposure includes being near nickel, sulfuric acid, and asbestos vapours.
  • Inadequate consumption of fruits and vegetables

Types of throat cancer

Most kinds develop in the thin, flat cells surrounding the voice box and throat.

There are two primary varieties of throat cancer:

  • Pharyngeal cancer – Your nose and oesophagus are connected by a tube called your throat (pharynx). Food travels through your oesophagus from the back of your throat to your abdomen.
  • Laryngeal cancer – Your vocal cords are located in your voice box (larynx), which is located at the base of your throat.

Doctors further segment these groups by identifying them geographically. You could develop pharyngeal carcinoma if you:

  • Nasopharynx – Behind your nose is the upper portion of your throat.
  • Oropharynx – You have this area behind your mouth. The soft palate, back of the tongue, and tonsils are where cancer is most likely to spread.
  • Hypopharynx – The tiny space beneath your voice box is there.

The vocal cord itself has three areas where cancer can spread. First, you could develop laryngeal carcinoma if you:

  • Second, the glottis. This supports the voice cords.
  • Second, supraglottis. This is the region above the glottis.
  • Subglottis. This is the region that is above your windpipe and below your vocal cords.


During your physical examination, your doctor will inquire about your sexual history, smoking and drinking habits, and overall health. They might employ equipment to acquire a better view of your neck. Depending on the type of cancer the doctor suspects you may have, they will order testing and treatments. A tissue sample is taken during a biopsy and inspected under a microscope to check for cancer cells. It is the sole means of identifying a tumor’s type and determining if it is cancer. Surgery, tiny needles, or an endoscope—a flexible tube with a camera inserted into the oesophagus through your nose or mouth—can all be used to treat it. The biopsy will be taken with an instrument on end.

Doctors can use imaging scans to discover tumours. They can also demonstrate its size and whether it has spread. These consist of:

CT or MRI scan

X-rays for PET scans

If oropharyngeal cancer is discovered, the sample could be examined for HPV. If a person’s illness is determined to be caused by this virus as opposed to a malignancy brought on by smoking, their prognosis for recovery is typically better.

Stages of throat cancer

There are specific guidelines for staging, which identify the severity of the disease for each kind of cancer.

Stages I and II malignancies, however, typically affect a lesser portion of the organ and remain localised.

Diseases in stage III can spread to the throat’s lymph nodes or other areas.

Additionally, stage IV tumours may have migrated to the lymph nodes, the head, the neck, or the chest. Finally, stage IV tumours, which are the most dangerous, have spread to distant organs like the lungs or liver.


The tumour will be removed, cancer will be stopped from growing, and your ability to swallow and talk will be preserved as much as possible.

Your medical care will be based on:

  • The cancer stage you possess
  • It’s location
  • Your general well-being
  • what you prefer

One or more treatments could be given to you.

Radiation therapy – High-energy beams are used in radiation to destroy cancer cells. It is delivered either externally by a machine or internally by radioactive seeds sown close to the tumour. For early-stage malignancies, radiation therapy may be the sole necessary treatment. However, it can be used with chemotherapy or surgery to treat advanced diseases.

  • Surgery -A scalpel can be used to make incisions for surgical procedures. Using lasers, robotics, or an endoscope to enter through the mouth could all be less invasive alternatives. Lasers or endoscopes can typically remove very early malignancies. Your larynx or pharynx may need to be removed entirely or partly, depending on how far along your cancer is. This may impact your capacity to breathe, swallow, or speak normally.
  • Doctors may reconstruct a portion of your throat to aid with swallowing using tissue from another region of your body. If your voice box is removed, the surgeon will connect your windpipe to a stoma—a neck opening—so you can breathe. In addition, your surgeon may perform an operation to remove lymph nodes if cancer has spread deep within your neck.
  • Chemotherapy – Drugs used in chemotherapy can treat cancer and inhibit it from spreading. It can be taken before or after surgery to reduce tumour size and prevent the disease from returning. In addition, certain chemotherapy medications can improve radiation.
  • Targeted therapy – By preventing the nutrients that cancer cells need to develop, targeted treatment medications can starve cancer cells.


1. How to prevent throat cancer?

Smokers are more likely to develop throat cancer. Nonsmokers, however, can also get it in some circumstances. Therefore, it’s imperative to stop smoking.

The following are the negative effects of smoking:

  • Decreases the efficacy of the treatment being given.
  • It has an impact on the body’s healing process.
  • Increases the risk of other malignancies as well.
  • The risk of throat cancer is significantly increased by smoking and alcohol use. Therefore, it’s advisable to cease drinking alcohol because it contributes independently.
  • People are urged to use the professional assistance that is constantly available to individuals who want to quit drinking or smoking.
  • It is imperative to emphasise the value of a diet high in fibre.
  • It is advised to have frequent HPV screenings.

2. How is throat cancer examined?

To examine the throat, the doctor might wish to do an endoscopy. An endoscope with a camera is inserted into the patient’s mouth. The doctor can see the camera’s output on a display device after it has been enlarged. This makes it easier to see clearly and makes it easier to detect abnormalities. The physician may also employ a laryngoscope to check the voice box mainly. If anything worrisome is found, a biopsy could be performed immediately, in which a few cells are taken and transferred to the lab for additional analysis.

3. What are the main symptoms of throat cancer?

The following signs are some to be on the lookout for:

  • Irritation in your throat
  • Having trouble swallowing?
  • An ulcer that doesn’t heal A change in voice
  • chronic earache
  • Unaccounted-for weight loss

An oncologist must be seen to rule out throat cancer if any of the above-mentioned symptoms persist for a long time.
