Oral squamous cell carcinoma make up a large percentage of oral cancers. They usually occur on the lips and tongue, often appearing as a lump or ulcer. Some common symptoms include the presence of a sore that won’t heal; loose teeth, pain in the tongue or jaw; difficulty chewing and swallowing; and a sore throat. In order to diagnose oral squamous cell carcinoma, Dr Patterson will do a thorough physical examination, during which he will examine the lips and mouth and check for any visible abnormalities such as sores, ulcers or areas of particular sensitivity. If anything abnormal is found, he may do a biopsy, which will involves a small tissue sample being removed and sent for testing in a laboratory. Treatment will depend on the findings of the test, and may include surgery, chemotherapy or radiation therapy.
