Tests and procedures used to diagnose lip cancer include:
- Physical exam. During a physical exam, your doctor will examine your lip, mouth, face and neck to look for signs of cancer. Your doctor will ask you about your signs and symptoms.
- Removing a sample of tissue for testing. During a biopsy, your doctor will remove a small sample of tissue for laboratory testing. In the laboratory, a doctor who analyzes body tissue (pathologist) can determine whether cancer is present, the type of cancer and the level of aggressiveness that's present in the cancer cells.
- Imaging tests. Imaging tests may be used to determine whether cancer has spread beyond the lip. Imaging tests may include computerized tomography (CT), magnetic resonance imaging (MRI) or positron emission tomography (PET).
