Oral Mucosa: Concerns About Red Lesions on the Lip - Dentistry

Share to:

Oral mucosa


Hello, doctor.
I do not smoke or drink alcohol, nor do I have a family history of cancer.
About three weeks ago, I accidentally discovered a small area on my upper lip mucosa that is red, measuring approximately 0.2 x 0.4 cm.
The color sometimes appears lighter and sometimes darker.
It feels smooth to the touch and is not painful.
I am worried about malignancy, so I frequently check and touch it.
I have visited the hospital and consulted two oral surgeons, both of whom indicated that it does not appear to be a malignant change based on both touch and appearance.
They mentioned that the blood vessels are more prominent, which is why it looks red.
However, I still cannot ease my mind.
I would like to ask the doctor if it could possibly be oral erythroplakia or lip cancer, considering it is still in the early stages.

If it is oral erythema, the surface may be rough, and it can sometimes be complicated by ulcers and pain.
It is recommended to consult an oral surgeon for further evaluation, and if necessary, a biopsy can be performed.

It's understandable to be concerned about any changes in your oral mucosa, especially when it comes to red lesions on the lip. Based on the information you've provided and the previous consultations you've had with oral surgeons, it seems that your situation is not uncommon and often benign.
Red lesions on the lip or oral mucosa can arise from various causes, including irritation, inflammation, or even minor trauma. Given that you have no history of smoking, alcohol consumption, or betel nut use, and considering your family history is clear of cancer, the likelihood of a malignant transformation is significantly reduced.
The fact that the lesion you described is small (0.2x0.4 cm), smooth to the touch, and painless is reassuring. Malignant lesions often present with additional symptoms such as pain, ulceration, or changes in texture. The variability in color you mentioned—sometimes appearing lighter and other times darker—can be attributed to factors such as blood flow, irritation, or even the foods you consume.
You mentioned that two oral surgeons have assessed the lesion and indicated that it does not appear to be malignant. They suggested that the redness could be due to prominent blood vessels, which is a common occurrence and not necessarily a cause for concern. Conditions like oral lichen planus or geographic tongue can also cause red patches in the mouth, but these are typically benign and manageable.

As for your concern about oral erythroplakia (red patches) or lip cancer, it's important to note that while these conditions can occur, they are more likely to present with additional symptoms and risk factors. Early-stage lip cancer may show signs such as persistent sores, changes in texture, or growth over time. Since your lesion has remained stable and has been evaluated by specialists, the risk of it being a malignant condition is low.

To address your anxiety, it may be beneficial to adopt a routine of regular check-ups with your healthcare provider. Monitoring the lesion every few months can help ensure that any changes are noted early. Maintaining good oral hygiene and avoiding irritants (like spicy foods or harsh dental products) can also help reduce inflammation and irritation in the oral cavity.

In summary, while it's natural to worry about changes in your body, the assessments you've received suggest that your red lesion is likely benign. Continue to observe the lesion, maintain regular dental check-ups, and consult your healthcare provider if you notice any significant changes or if new symptoms arise. Your proactive approach to your health is commendable, and staying informed will help you manage your concerns effectively.
