Throat cancer is a subgroup of head and neck cancers. It typically refers to cancers that originate in the pharynx (the throat). Thickened white patches on the lining of the throat are usually the earliest signs of cancer or a precancerous condition in the throat.

The most common type of throat cancer is called squamous cell carcinoma (SCC). This and other types of throat cancers are most often caused by environmental factors, including smoking or chewing tobacco. Infection with human papillomavirus (HPV) is an increasing cause as well. Additional exposures that increase the risk for throat cancers include alcohol and betel quid, a stimulant used in Asia.

Nearly 60% of Americans surveyed support a Medicare for All program, according to Business Insider. Those in favor of Medicare for All include 75% of Democrats, 58% of registered Independents and 36% of Republicans, though Republican support jumps up to 64% when discussing an optional expanded Medicare program, also referred to as “Medicare for Some.”

According to the National Cancer Institute, there were more than 53,000 cases of oral and pharynx cancer in 2020. Approximately 10,000 patients who have been diagnosed with these cancers died. The five-year survival rate for these cancers is about 66%.

This article reviews the appearance of several types of throat cancers and briefly describes their symptoms.

A White Patch

Some throat cancers begin as oral leukoplakia, a general term for a white lesion in the mouth of an unknown cause.

Leukoplakias are premalignant lesions, which means they’re not cancerous yet, but could develop into cancer. About 3% to 17.5% of these lesions are or will become cancerous in 15 years, while others go away independently.

Common symptoms of oral leukoplakia include a persistent cough and sore throat lasting for more than three weeks.

A Red Patch

Other throat and mouth cancers show up as red patches called erythroplakias. These are rare, isolated, velvety patches in the mouth and/or throat that typically show up in older patients.

Erythroplakia lesions are usually premalignant, but most of these red patches become cancerous, so it’s important to get them checked out. They typically affect middle-aged and elderly people, and are usually linked to tobacco and alcohol use.

Sometimes, lesions are a mix of red and white, referred to as erythroleukoplakias or “speckled leukoplakias.” Although the lesions most commonly occur on the floor of the tongue, they can also develop on tissues behind the back teeth, including the upper throat.

Throat Ulcers

A classic sign of oral cancer is a persistent rough patch that looks like a sore and has a raised border. Unlike some ulcers and other lesions like canker sores, these are minimally painful.

A Lump in the Throat

A primary tumor of the throat can appear as a nodular mass on the floor of the mouth, tongue, tonsil, or wall of the throat. The mass will tend to be irregular, fixed, and relatively painless, but can interfere with swallowing and make you feel like you have something caught in your throat. This is most common in people with a long history of smoking.

A Lump in the Neck

Metastasis is the spread of cancer from its original location. Head and neck cancers can spread through the lymphatic system, which is another circulatory system of the body. In the lymphatic system, fluid flows to lymph nodes, where white blood cells act to remove or neutralize foreign substances and invaders such as bacteria, viruses, and cancer cells.

If throat cancer spreads through the lymph vessels, it will likely land in the lymph nodes of the neck. There, it can produce non-tender masses (lymphadenopathy) and then seed new tumors in other parts of the body.

When a primary tumor grows to a large size, it can cause difficulty swallowing or talking, earaches, headaches, spitting up blood, and sometimes partial airway obstruction.

A Swollen Tongue

Some throat cancers, specifically those associated with a human papillomavirus (HPV) infection, cause a swollen tongue.

Infection with HPV is one of the major causes of throat cancer. About 10% of men and 3.6% of women have oral HPV. Many cases clear on their own, but some persist for years, which is when cancer can develop.

HPV-related oropharyngeal cancers are limited to the throat, while those caused by smoking, tobacco use, or other environmental triggers are found in the mouth and lips as well.

The characteristic symptoms of HPV-associated throat cancer include a swollen tongue, tiny lumps inside the mouth, and mouth numbness. The persistence of symptoms is a telltale sign, particularly in younger people who do not smoke.

Human papillomavirus is an infection that we can prevent. The HPV vaccine is very safe and effective at preventing infections, genital warts, and precancers.

Hardened Tissues

Another type of throat cancer, submucous fibrosis, is defined by the hardening of mucosal tissues. It is most often caused by the chewing of betel nut in Southeast Asian cultures, but also sometimes seen in people who chew tobacco.

Submucous fibrosis is typically a precancerous disorder, but can become malignant in between 1.5% and 15% of cases.

These lesions typically start in the mouth and gums, but can also involve the throat. They can cause burning sensations after eating spicy foods, and cause pain when eating and difficulty opening the mouth.

Advanced Symptoms

Coughing up blood is extremely rare. It can result from timor cells eroding into blood vessels. This is a sign of end-stage disease with a grim prognosis. An additional symptom is loose teeth, which can develop as the tumor spreads to the bones of the jaw and teeth.

You may also notice changes in the voice if cancer spreads to the larynx. Large primary tumors can prevent swallowing, leading to poor nutrition. Weight loss and persistent fatigue may result from this or be the result of widespread metastasis.

A Word From Verywell

Symptoms alone cannot diagnose throat cancer. If you’re worried about cancers of the head and neck, perform periodic oral self-exams. Making regular dental visits can also be a good way to monitor for any unusual growths or lesions.

A diagnosis of throat cancer is made after much testing and examination by your doctor. Tests will include a physical exam, where your doctor will use their hands to feel for swollen lymph nodes and other nodules. They’ll also test to see if you have HPV.

They will do an endoscopy (a procedure in which a tiny camera is fed into your mouth through a tube), a biopsy of any suspicious lesions, and imaging like a computed tomography (CT) scan or magnetic resonance imaging (MRI).

If you’re a smoker and have unusual or persistent symptoms aligned with those above, speak to your doctor about getting further testing.

White Spots on Throat: 6 Common Causes (Images Included)

White spots on throat are usually a symptom of a viral or bacterial infection. If you have white patches on your throat, you will probably have other symptoms as well.

Some of the accompanying symptoms of white spots in throat could be:

• White spots on the tonsils which are inside the throat
• Swollen glands in your neck
• Sore throat
• A dry throat
• Unpleasant taste in mouth

If you notice white patches on your throat or on your tonsils then it is always best to have them checked out because, left untreated, they can lead to more serious conditions. However, there are many natural remedies you can use to help ease the discomfort associated with throat infections.

If you have noticed white dots on your throat, what are the main causes of them?

What Causes White Spots on Throat?

There are a number of different reasons why white spots or patches can appear on your throat or tonsils. Here are the most common reasons:

1. Strep Throat Can Cause White Patches in The Back of Throat

One of the reasons for the appearance of white spots on the throat is a bacterial infection called strep throat. It is caused by Streptococcus pyogenes bacteria.

Although strep throat mainly affects children and teenagers, it can also affect adults. While one of the symptoms of a strep infection is a sore throat, it only accounts for around 30% of throat infections in children and about 10% in adults. 1

Apart from causing your throat to be sore, some of the other symptoms of strep throat are:

• Pain when you swallow
• A fever
• Swollen tonsils and lymph nodes
• White spots or red sores on tonsils

Family physician, Dr. Kathleen Romito, says that if you have cold symptoms like a blocked or runny nose and sneezing, then you probably don’t have a strep throat. 2

How to treat strep throat naturally

There are many natural remedies which can help to treat mild to moderate cases of strep throat.

However, if you have a more serious case, you should always seek medical advice. If left untreated, strep throat can lead to serious infections in other parts of the body because the bacteria can spread to other organs. The most serious complication of strep throat is rheumatic fever. 3

Even if your doctor has prescribed a course of medications to treat strep throat, you may still use natural remedies alongside to help the treatment (but remember to consult with your doctor about it).

One of the natural remedies for strep throat is cayenne pepper. Cayenne pepper contains capsaicin which has proven antibacterial properties. For example, a study published in Frontiers in Microbiology found that capsaicin was effective against Streptococcus pyogenes bacteria and it can help prevent the infection spreading to deep tissues. 4 It is also effective in relieving pain 5 and reducing inflammation. 6

You can make a paste with cayenne pepper by mixing 1 teaspoon with half a cup of coconut oil or other carrier oil, or buy a ready made cream in the drugstore.

Because capsaicin is strong and might hurt your throat, and since it is well absorbed by your skin, apply the capsaicin cream or paste to the skin on your throat and on the swollen lymph nodes on your neck.

For more information, please read my article about the best natural remedies for strep throat.

It is good to remember that strep throat is highly contagious and you should make sure that you wash your hands often and cover your mouth if you cough. Avoid sharing utensils like cups, knives, and forks.

2. Tonsillitis can Cause White Spots on Tonsils and in the Back of Throat

Tonsillitis can cause white spots in your throat and on your tonsils. Tonsillitis happens when the tonsils, the 2 lymph nodes located at the back of your throat, become infected and inflamed. It can be caused by a bacterial infection (like streptococcal bacteria) or a viral infection.

Other symptoms associated with tonsillitis are a sore throat, fever, headache, stiff neck, and swollen tonsils. Quinsy is a complication of tonsillitis and it causes pain on one side of your throat.

It is important to diagnose the cause of tonsillitis because if it is caused by a serious bacterial infection, antibiotics may be needed. If you take antibiotics, make sure to do these 3 things to restore healthy intestinal flora.

If the tonsillitis is caused by a virus then very often natural remedies can help to treat and relieve the symptoms.

Natural treatments for tonsillitis

One of the most effective natural ways to treat tonsillitis is to gargle with salt water. All you have to do is to mix 1/2 to 1 teaspoon of salt in an 8 oz glass of water. Gargle several times during the day.

You can also make a delicious Echinacea tea by steeping Echinacea and ginger in hot water. When it has cooled add some lemon and honey and drink 2-3 times a day. All of these ingredients can help to relieve tonsillitis. For more detailed information, read my article on how to use Echinacea tea for a great health.

3. Tonsil Stones (Tonsilloliths) Look Like White Bumps on the Back of Throat

Tonsilloliths, also known as tonsil stones look like white spots or balls on the back of the throat.

Depending on their size, tonsil stones could also irritate the back of your throat and they often get coughed up into the mouth. Tonsil stones can be physically irritating, leaving you feeling as if something is stuck in your throat.

Tonsil stones are actually white formations on your tonsils at the back of your throat. This white stuff or chunks form when “debris” like bacteria, mucus, food and dead skin cells get trapped in and around your tonsils. In time they calcify, causing them to look like small white bumps on your tonsils. However, many people with tonsil stones can’t see them.

One common symptom of tonsil stones is chronic bad breath. This is because tonsil stones are full with bacteria that pack quiet a stinky smell and distinct odor. A study published in the British Dental Journal found that 75% of people with halitosis (chronic bad breath) also had tonsilloliths. 7

Other common symptoms of tonsil stones can be sore irritated throat, swollen red tonsils, earache, and in extreme and rare cases difficulty breathing.

A Japanese study that conducted by researchers at the Tokushima University in 2014 found that tonsil stones is a common condition that occurred in close to 40% of patients, with the prevalence increasing with age. It is more common among people who have suffered from tonsillitis and inflammation of the tonsils.

Common causes and treatments for tonsil stones

Although tonsil stones may happen to even the healthiest mouth and to people of any age, they are more common in those who have insufficient oral hygiene and in teenagers or people with larger tonsils (more surface area means more room for stones to build up).

One of the best ways to prevent tonsil stones forming is to practice good oral hygiene. This means brushing your teeth twice a day, regularly flossing, and brushing your tongue. This can help to remove bacteria and the “debris” that can come together to form stones.

If you have tonsil stones, there are a number of natural ways to get rid of them. Sometimes, just a salt water gargle is enough to help dislodge the stones.

4. Oral Thrush Looks Like White Patches or Clumps on Back of Throat

Oral thrush can appear as white patches on your throat, tongue, tonsils, and roof of your mouth and can leave you with a ‘cottony’ feeling in your mouth.

Oral thrush is usually a result of yeast infection that is caused when there is an imbalance of “good” bacteria in the body and it allows fungal infections to develop. For example, a Candida fungal infection in the mouth is an example of oral thrush.

The Mayo Clinic reports that one of the most common reasons for oral thrush is taking antibiotics, which disrupt the balance of bacteria in your body. 8

If you are taking antibiotics then it is recommended that you also take probiotics to help restore the natural flora in your digestive system. This can help prevent outbreaks of oral thrush. A study published in the journal Critical Care Medicine showed that probiotics helped to prevent candida infections while children were taking antibiotics. 9

You can also consume fermented foods to boost the good gut bacteria and improve digestive, cardiovascular and immune health.

Another option for treating oral thrush is coconut oil and this is due to its antifungal properties. For more information, read my ultimate guide on how to use coconut oil for oral thrush and yeast infections.

5. Mononucleosis can Cause White Spots on Tonsils

Mononucleosis (sometimes just called mono) is a contagious viral infection which can cause white spots on your tonsils and in your throat.

Some of the other symptoms of mononucleosis are fatigue, sore muscles, headaches, and a loss of appetite.

Mononucleosis is caused by a virus (Epstein-Barr virus, or EBV) and although it isn’t a serious illness, it can affect a person’s daily activities.

Mononucleosis is a very infectious disease and it tends to affect mainly teens and young adults. However, most adults already have antibodies against mononucleosis which prevent them from catching it again. Mononucleosis is generally spread by saliva and is sometimes referred to as the “kissing” disease.

One of the symptoms of mono is sore throat, often with white patches on the tonsils (which may look like strep throat). Other symptoms of mono are fever, swollen lymph nodes, headache and fatigue.

Dr. E. Gregory Thompson from WebMD said that one complication with mono is an enlarged spleen, and it is recommended that people with mono avoid lifting heavy items and engaging in contact sports to reduce the risk of spleen injury. 10

If you have mononucleosis the best course of treatment is plenty of rest and to drink plenty of fluids. If you have a sore throat, then you can use natural treatments such as calendula tea, homemade syrup or natural pain killers (that you may already have in your kitchen).

6. Leukoplakia can Cause white Patches in the Throat

Leukoplakia is a less common condition which can cause white spots on throat and mouth.

Mild leukoplakia isn’t classed as a dangerous disease and will usually go away on its own. However, on rare occasions, more serious cases have been linked to oral cancer. 11 It is common in people who smoke or chew tobacco, although it can also be caused by other irritants in the mouth.

Leukoplakia can sometimes be caused by gastroesophageal reflux disease (GERD). This is where the acid from the stomach comes back up into the esophagus. Common symptoms of GERD are heartburn or acid indigestion. A study published in Medscape General Medicine said that GERD can also cause leukoplakia. 12

Doctor of dental surgery, Dr. Michael Friedman recommends removing the source of irritation. This can mean that a person stops smoking or using other tobacco products. 13 If the dentist or doctor thinks that it is a serious case, then a biopsy may be taken. However, most cases of leukoplakia are mild and go away on their own.
