The small bumps on the tongue?


Hello Doctor: Recently, I noticed small, lump-like protrusions at the back of my tongue (near the throat).
They are not painful, but I am unsure what they are and whether they indicate any disease.
I have not noticed this symptom before, so I am curious why it has suddenly appeared.
Could you please provide an explanation? Thank you!

Dr. Ye Dawei reply Otolaryngology


If these protrusions are not hard and there is no bleeding, they are likely harmless.
However, please visit an outpatient clinic for a physician to examine them to rule out the possibility of malignant changes.

More Info


The presence of small bumps on the back of the tongue, particularly near the throat, can be concerning for many individuals. These bumps may be a normal anatomical feature or could indicate an underlying condition. Here, we will explore the potential causes of these bumps, their implications, and when to seek medical advice.


Potential Causes of Bumps on the Back of the Tongue
1. Normal Anatomical Variations: The back of the tongue contains various structures, including taste buds and papillae. Sometimes, these can appear as small bumps and are completely normal. The circumvallate papillae, for instance, are larger bumps located at the back of the tongue and can be mistaken for abnormal growths.

2. Lingual Tonsils: The lingual tonsils are located at the base of the tongue and can become enlarged or inflamed due to infections or allergies. This enlargement can create the appearance of bumps.

3. Infections: Viral infections, such as the common cold or flu, can lead to inflammation of the throat and tongue, resulting in temporary bumps. Additionally, oral herpes can cause lesions that may appear as bumps.

4. Allergic Reactions: Allergies to certain foods or substances can cause swelling and bumps on the tongue. This is often accompanied by other symptoms, such as itching or swelling in other areas of the mouth.

5. Oral Candidiasis: A fungal infection, commonly known as thrush, can cause white patches and bumps on the tongue. This condition is more common in individuals with weakened immune systems or those taking antibiotics.

6. Benign Growths: Conditions such as fibromas or papillomas can lead to the development of small, non-cancerous growths on the tongue. These are usually painless and do not require treatment unless they cause discomfort.

7. Cancerous Lesions: While less common, persistent bumps that do not resolve over time could indicate oral cancer. This is particularly a concern if the bumps are accompanied by other symptoms such as pain, difficulty swallowing, or changes in speech.


When to Seek Medical Attention
If you notice new bumps on the back of your tongue, it is essential to monitor them for changes. Here are some guidelines on when to seek medical advice:
- Duration: If the bumps persist for more than two weeks without improvement, it is advisable to consult a healthcare professional.

- Accompanying Symptoms: If you experience pain, difficulty swallowing, changes in taste, or any other concerning symptoms, seek medical attention promptly.

- Changes in Appearance: If the bumps change in size, color, or texture, or if new bumps develop, it is important to have them evaluated.


Conclusion
In summary, small bumps on the back of the tongue can arise from various causes, ranging from normal anatomical features to infections and benign growths. While many cases are harmless, it is crucial to remain vigilant and consult a healthcare provider if the bumps persist or are accompanied by other symptoms. Regular dental check-ups can also help monitor oral health and catch any potential issues early. Always prioritize your health and do not hesitate to seek professional advice when in doubt.
