Oral cancer diagnosis involves several steps and procedures to accurately identify the presence of cancerous cells in the mouth. Here is a comprehensive overview:
- Initial Examination
- Visual Exam: A healthcare provider will examine the mouth, lips, and throat for any signs of abnormal growths, sores, or discolored patches.
- Physical Palpation: The provider may feel the tissues in the mouth and neck for lumps or irregularities.
- Medical History: The provider will take a detailed medical history, including any risk factors such as tobacco use, alcohol consumption, HPV infection, and family history of cancer.
- Diagnostic Tests
- Brush Biopsy: A small brush is used to collect cells from a suspicious area for analysis.
- Incisional Biopsy: A small section of the suspicious tissue is surgically removed for microscopic examination.
- Fine Needle Aspiration (FNA): A thin needle is used to extract cells or fluid from a lump for analysis.
- Imaging Tests:
- X-rays: To check for cancer spread to the jaw or chest.
- CT Scan: Provides detailed cross-sectional images of the body to check for tumors.
- MRI: Uses magnetic fields to create detailed images of soft tissues in the body.
- PET Scan: Helps to identify cancerous cells by detecting areas of high metabolic activity.
- Endoscopy: An endoscope (a thin, flexible tube with a light and camera) is used to examine the throat and other parts of the mouth more closely.
- Molecular Testing: Tests may be conducted on biopsy samples to identify specific genes, proteins, and other factors unique to the cancer, which can help guide treatment.
