What are the possible causes of a bump on my lip?

There are several reasons why you might have a bump on your lip. One common cause is an infection. Viruses or fungi can sometimes cause small bumps to appear on the lip. Cold sores are one such example. These bumps are usually temporary and go away on their own. Another possibility is that the bump is forming as your body heals after a small injury, like accidentally biting your lip. The healing process can sometimes create a little extra tissue in one spot. In some cases, the bump could be a benign growth such as an oral neural neoplasm. This means it is made up of nerve cells and is usually not harmful. Very rarely, a bump might be an early sign of oral squamous cell carcinoma, a type of cancer. However, these cancerous bumps are less common and usually come with changes like alterations in size, color, or shape. If you're concerned about a bump on your lip, you can check your symptoms to help determine the possible cause and whether you should see a doctor for the right treatment.
