An individual may occasionally notice what looks like a small white lesion or spot on a tonsil. This is typically known as a tonsil cyst or tonsillar cyst. A tonsil cyst is a pouch-like vesicle filled with fluid or pus typically protruding from a tonsil. Most frequently, these tonsil cysts are benign, although in some cases, cancer may be present. A benign tonsil cyst can become infected if not treated in a timely manner.

There are danger signs and warnings to look out for with cysts that have formed on the tonsils. Difficulty in swallowing or anything that prevents the patient from eating normally should be brought to a doctor's attention. General bleeding from the area is not typical with tonsil cysts, although some cases may differ.

Antibiotics are often prescribed for patients with tonsil cysts.

Tonsil cysts differ from tonsil stones, which are known as tonsilloliths. A tonsil cyst is generally softer and not solid as a stone would be. Cysts seem more like bumps in appearance. With the presence of cysts located on the tonsils, the typical procedure involves a physician performing a biopsy of the tissue. This is done to examine the cells and ensure there are no signs of cancerous tissue present. A doctor can generally tell if the cyst is infected by the fluid matter that drains from it.

Using antiseptic mouthwash is recommended for those with tonsil cysts.

In some patients who suffer from frequent sinus infections or inflamed tonsils, fluid can become trapped and form into a 'pocket.' This sac then becomes a tonsil cyst. Under most circumstances, the doctor might decide to remove the cyst, unless it shows signs of draining on its own. Typically, the doctor will prescribe a course of antibiotics to treat the infection or prevent one from developing. If the tonsils are inflamed and infected, the physician may consider removing them through a surgical procedure known as a tonsillectomy.

Tonsil cysts, or tonsil stones, are small, yellowish in color, and form in the back of the throat within the tonsils.

In many cases, a general practitioner may refer the patient to a specialist who treats diseases and conditions of the throat. Such a physician is an ear, nose and throat specialist (ENT), professionally known as a otorhinolaryngologist. The specialist, who is typically qualified to perform surgery, will most likely have recommendations for the patient. He may tell his patient to refrain from smoking, as this can cause further irritation. Gargling with an antiseptic mouthwash might also be recommended.

If a patient requires removal of the tonsil cyst as well as a tonsillectomy, the physician generally prefers to wait until the infection has been cleared. This is generally after a 10-day course of antibiotic treatment and evaluation. It is considered to be safer to operate when there are no signs of infection present.

Can I Treat Tonsil Cyst Naturally or at Home?

While tonsil cysts don’t always pose immediate harm, it’s still essential to have a healthcare professional check if a patient discovers cysts in their tonsils. Furthermore, a doctor should immediately examine one who has cysts accompanied by fever, muscle fatigue, stiff neck, or a persistent sore throat.

Tonsil cancer can be mistaken for tonsil cysts since their symptoms are very similar. If a patient is experiencing the symptoms of tonsil cysts, it’s best to take precautions and see a doctor.

If tonsil cysts have been confirmed, the doctor may prescribe antibiotics. In complicated cases, or in cases where the cysts are recurring, doctors might recommend having the tonsils removed surgically.

Tonsil cysts need immediate medical care, as delaying treatment can lead to severe infections.

Tonsil cysts can be prevented by taking precautions at home. These cysts are symptoms of infections in the tonsils, otherwise called tonsillitis. The infection is commonly caused by mononucleosis (mono) and bad dental hygiene. Therefore, maintaining good dental and gum hygiene can help prevent infections from occurring in the tonsils.

What Happens When Your Tonsil Cyst Bursts?

A tonsil cyst that bursts or ruptures on its own can be extremely dangerous and even life-threatening. When a tonsil cyst bursts, the puss-filled fluid released from the ruptured cyst can travel down the throat and spread infection throughout the body. The pus and bacteria can even spread into the lungs and cause pneumonia

Ruptured or burst tonsil cysts are incredibly dangerous. For this reason, the goal of treating tonsil cysts is to treat the abscess early.

What Happens When Your Tonsil Cyst Bursts?

Tonsil cancer doesn’t form cysts. However as mentioned earlier, tonsil cysts and tonsil cancer have many of the same symptoms. For this reason, it’s difficult to know whether the condition is a cyst or cancer without a thorough checkup and testing by a healthcare professional.

Symptoms that overlap between tonsil cysts and tonsil cancer include:

  • Difficulty eating or swallowing
  • Ear pain
  • The feeling that something is stuck in the back of the throat

Since it is difficult to visually differentiate between tonsil cysts and cancerous tumors, patients must seek proper care from a general practitioner or better yet, an ENT.

General practitioners can sometimes differentiate between a tonsil cyst and a cancerous tumor from the appearance. The difficulty comes with the similarity between sores from tonsil cancer and tonsil cysts.

Suppose the doctor or general practitioner suspects cancer. In that case, they will conduct a biopsy on the abscess to see if the lump is cancerous. They might also perform an imaging test, such as a magnetic resonance imaging (MRI), a PET scan, or a computed tomography (CT) scan, to determine whether or not cancer has spread. 

If cancer is detected, there are several treatment options a healthcare provider might take. Transoral robotic surgery (TORS) is performed on patients in the early stages of cancer. 

Radiation therapy uses a high-energy radiation beam to kill cancer cells. It shrinks tumors or kills off any remaining cancer cells after surgery. Chemotherapy is often used alongside radiation therapy to kill any slow-growing cancer cells. 

The prognosis for tonsil cancer is generally favorable even if induced by human papillomavirus (HPV). Eighty-five to Ninety percent of tonsil cancers caused by HPV are expected to survive. The earlier the cancer is detected and treated, the more likely the patient is to recover fully. 

Can You Get Tonsil Cysts If You Don’t Have Tonsils?

Oddly enough, people can get tonsil cysts even if they don’t have tonsils but this occurs only in extremely rare cases. 

As mentioned earlier, tonsillectomy is a procedure where the tonsils are surgically removed. This routine surgery is commonly conducted on children who experience frequent tonsil infections. Getting a tonsillectomy does reduce the risk of developing diseases in the tonsils. However, the risk doesn’t outright disappear. 

Some tonsil tissue is left behind during a tonsillectomy, and the leftover tonsil tissue can form tonsil cysts. For this to occur, the infection must take place in tissues near the tonsil, such as the pharynx, gums, or tongue. 


Tonsil cysts, while relatively minor, can cause significant suffering and even worse when left unchecked. Knowing the different symptoms, treatment options, and similarities of tonsil cysts with other diseases is worthwhile especially when the consequences are so dire. Prevention beats a cure, so patients following the suggestions above should live happily with healthy tonsils.

Frequently Asked Questions

What is a tonsil cyst?

A localized collection of fluid-filled sacs that form in the tonsils is known as a tonsil cyst. Yet, if they become infected, they can be uncomfortable even though they are normally benign and seldom cause any symptoms. 

Although these may happen to adults as well, children exhibit them the most frequently. A blocked salivary gland, an allergic response, or an infection are the usual causes of tonsil cysts. Cysts can be as little as a few millimeters or as large as several centimeters. 

What are the symptoms of a tonsil cyst?

The majority of tonsil cysts are not symptomatic and are only found during a physical examination. A tonsil cyst that is infected can result in discomfort, soreness, and trouble swallowing or breathing, among other symptoms. Moreover, an infected cyst might cause fever, sore throat, and lymph node enlargement. Sometimes, the cyst may manifest in the throat as a white or yellow lump.

What causes tonsil cysts?

Infections, allergic reactions, or blocked salivary glands are the most common causes of tonsil cysts. Although they may also occur in adults, they are more typically observed in youngsters. Not usually can the reason be determined.

How are tonsil cysts diagnosed?

Often, tonsil cysts are detected by physical examinations. A physician may also require imaging tests, such as an X-ray or CT scan, to confirm the diagnosis. In rare instances, a biopsy may be necessary to rule out alternate causes of the cyst.

How are tonsil cysts treated?

Treatment is often not necessary until a tonsil cyst becomes infected or impedes breathing or swallowing. A doctor may keep an eye on the cyst to make sure it doesn't become infected if it isn't already. Antibiotics may occasionally be administered to treat an infection. Occasionally, if the cyst is causing serious symptoms, it may be necessary to remove it surgically.

Just go to the ENT. I'm pretty sure 16 years of school wins over reading an article or what other non-doctors think.


@KoiwiGal - They might be harmless to your tonsils but they sure can give you a few sleepless nights until you work out what they are. I kept feeling like I had something in my throat and spotted a tiny lump of white on one of my tonsils.

I went to the internet and left convinced that the lump was cancer or a cyst or a symptom of strep or any number of things. Every time I looked at it, it seemed to be bigger (which I now realize was my imagination).

When I went to the doctor she basically explained that lots of people have tonsil stones and they are pretty easy to tell from cysts if you know what to look for. But it was pretty embarrassing. I don't want to discourage anyone from going to the doctor, but you need to try not to overreact.


@anon273547 - The cysts aren't food trapped in the area, those are the tonsil "stones" or tonsilloliths. The cysts are the same as any other kind of skin infections, basically. They might have several causes (including diseases like strep throat).

The stones are generally thought to be caused by a buildup of food getting caught in the tonsils, which is why they are usually associated with bad breath. But, generally, they are pretty harmless in terms of tonsil pathology.


Go to an ENT doc. If you have strep they can do a culture. I had the same thing and was walking around thinking I had cancer after a doctor freaked me out.

I had a CT scan but can't do the dye because of an allergy so they wanted to biopsy. The second doc said it looked like a cyst and come back in four weeks. He didn't feel it was necessary to biopsy. If it grows we will then biopsy and he could remove tonsil. He said cysts are food or something -- anything just trapped in that area. If it's cancer it grows fast from what I understand and it's hard, not soft to the touch.

I suggest you get it checked out, since ENT docs know what to look for.

Good luck. I am waiting mine out for the next month. I didn't even know it was there until a doc saw it in a routine exam. I still have no clue but the second doc said it appears to be a cyst.


A tonsil cyst doesn't hurt or bleed. It's a yellowish looking rounded and smooth bump. With strep or a throat infection, you would more than likely have a sore throat and redness. It would appear irritated. Tonsil cysts are painless. In my case, I didn't even know I had one until I went to have my stuffy ear looked at. The doctor saw it when checking my throat.

My ENT said to leave it alone as long as it doesn't bother me. But definitely go see your ENT.


I've had infectious mononucleosis in June. It began with severe tonsillitis which was mistreated with a antibiotic that put me in hospital due to an allergic reaction. Had two other antibiotics in the next 10 days.

A week ago my annual rhino-secretion at the back of my throat began which led to a very bad throat ache, swollen lymph nodes and tonsils. On the third day it began to look like tonsillitis and the pain got even greater with a fever of 37,4 C (not more). I've been treating my tonsils with whatnot, gargling, granophorin, soda, in an attempt not to take an antibiotic because my immune system had already been shattered enough.

Now a week later my throat doesn't hurt anymore, nor my nodes. It's just that there is a small (or not so anymore) hole in my left tonsil which is constantly filling up with white fluid which i swallow then it fills back in immediately. It's insane!

My doctor still doesn't have the idea of tonsil cyst. I feel like I'm fighting alone against that thing and nobody cares or knows what's going on!? The test says i have no bacterias which may cause an infection. So what the heck? Can a cyst be nonbacterial? -- Yoana


I have recently been feeling a lump in my throat kind of around where I would think the bottom of my tonsils would be, so I'm starting to wonder if I might have a tonsil cyst.

Of course, it's so low down in my throat that I'm also a little worried that it could be a laryngeal cyst. When I typed in my symptoms on webMD, they said that I could possibly have a laryngeal cyst, a tonsil cyst, a submandibular cyst, or a parotid tumor!

All those sound kind of scary, so I'm really not sure which one I'm "hoping" it is. I really hate going to the doctor, so I've been putting it off, but I'm afraid I may have to just bite the bullet and go, since it really is quite sore.

Before I go though, what do you guys think could be going on?


@Charlie89 -- I'm not sure how a doctor would tell the difference between a tonsil cyst and a tonsil infection, but here's what I would think they would look for.

The main symptoms of a tonsil cyst, according to the article, are pain swallowing and occasional bleeding. These differ quite considerably from most throat infections, which usually include a fever and more blister-like growths, rather than a big cyst.

Although the article does also say that the doctors usually take a biopsy -- so maybe you're right, maybe it is a hard diagnosis.

But if you're tonsils turn white, you're going to be going to the doctor anyway -- so what are you worried about?


How can you tell the difference between a tonsil cyst and, say, a severe case of tonsilitis or strep throat? I mean, without doing a test.

Does a tonsil cyst show up differently than a normal tonsil infection or swollen tonsil, or do they usually appear the same?

I guess I'm just wondering about how doctors diagnose these things to begin with. I mean, with a nasal cyst or an ear cyst it's not like you've got a whole lot of other options when you see something up there, but with a tonsil cyst, it could easily be confused for something else.

So the next time my tonsils turn white, should I be worried about a tonsil cyst, or is it most likely just a case of strep?
