There are several types of growths that may lead to your lips starting to swell. These growths may be cancerous or non-cancerous. Some growths are benign and simply start as a blockage in the salivary glands. These types of growths will typically go away on their own as the blockage works its way out. Some cancers occur in the mouth that may cause the lips to swell as well.
Squamous cell carcinoma is a form of cancer that may cause a person to experience swelling of the lips as well as other painful irritations in the mouth. If you are suffering from swollen lips and experiencing other pain, it is important to see your doctor right away to help determine the cause. A proper diagnosis is essential when it comes to getting the proper treatment started right away.
