a Small Bump on the Tongue: What Could It Be? - Otolaryngology

There is a small lump at the base of the tongue, approximately the size of half a grain of rice?


Hello, Doctor.
For the past couple of days, I've felt like there's something foreign on the right side of my tongue.
Later, when I looked in the mirror, I noticed a small bump about the size of half a grain of rice at the base of my right tongue, approximately 0.2 cm in size.
The color is close to flesh-toned but slightly white, and it feels somewhat hard to the touch, though I'm not sure if it's tissue.
It doesn't hurt, and there are no ulcers.
I also noticed a small similar bump on the left side, but it's much smaller.
I don't know if it's something similar.
I don't smoke or drink, and I'm 30 years old with no family history of oral cancer.
I would like to ask the doctor what this could be...
Could it be a tumor? Thank you, Doctor!

More Info


When it comes to small bumps or lesions on the tongue, there are several potential explanations, and it’s important to consider various factors such as the appearance, location, and associated symptoms. Based on your description, it seems you have noticed a small bump on the right side of your tongue, approximately the size of a grain of rice, with a color that is close to flesh-toned but slightly white. You mentioned that it feels somewhat hard, does not cause pain, and there are no ulcers present. Additionally, you noted a similar but smaller bump on the left side of your tongue.

First and foremost, it’s reassuring that you do not have any pain or ulceration associated with these bumps. This is a positive sign, as many serious conditions often present with discomfort or other symptoms. Given your age (30 years old), lack of smoking or drinking habits, and absence of a family history of oral cancer, the likelihood of these bumps being malignant is relatively low. However, it is still essential to consider various benign possibilities.

One common cause of small bumps on the tongue is the presence of papillae, which are normal anatomical structures. The tongue is covered with tiny bumps called papillae, which contain taste buds. Sometimes, these can become inflamed or enlarged due to irritation, trauma (like biting your tongue), or even infections. Another possibility is lingual tonsils, which are located at the back of the tongue and can sometimes appear as small bumps.

Another benign condition to consider is mucocele, which is a fluid-filled cyst that can occur in the mouth, including the tongue. These are usually painless and can appear as small, soft bumps. They often resolve on their own but can be removed if they become bothersome.

In some cases, the bumps could be fordyce spots, which are small, painless, pale bumps that are actually sebaceous glands. They are completely normal and harmless.

While the bumps you described do not seem to indicate a serious condition, it is crucial to monitor them. If they change in size, color, or if you develop any additional symptoms such as pain, difficulty swallowing, or changes in taste, it would be wise to consult a healthcare professional for further evaluation. A dentist or an ear, nose, and throat (ENT) specialist can perform a thorough examination and may recommend a biopsy if there is any concern about the nature of the bumps.

In summary, while the small bumps on your tongue are likely benign and could be attributed to normal anatomical variations or minor irritations, it is always best to err on the side of caution. Regular dental check-ups and being attentive to any changes in your oral health are essential for maintaining overall well-being. If you have any lingering concerns, don’t hesitate to seek professional advice for peace of mind.
