Overview
Biopsy of the tumor tissue is diagnostic of oral cancer. Other diagnostic studies for oral cancer include endoscopy, indirect pharyngoscopy, laryngoscopy, exfoliative cytology, barium swallow, chest x-ray and bone scan.
Oral Cancer Other Diagnostic Studies
Biopsy
- Only a biopsy can give a definitive diagnosis of oral cancer.
- The types of biopsies typically used for diagnosing oral cancers are:[1][2]
- Incisional biopsy
- Fine needle aspiration (FNA)
- Sentinel lymph node biopsy
Endoscopy
- Endoscopy is used to examine areas inside the body for the diagnosis, staging and treatment of cancer. Endoscopy is used to:[3][4]
Indirect pharyngoscopy and laryngoscopy
- Indirect pharyngoscopy and laryngoscopy check for any signs of oral cancer and to examine the back of throat.
- People diagnosed with oral cancer are also at an increased risk for other head and neck cancers, so a doctor will also examine the nasopharynx.
Exfoliative cytology
- Exfoliative cytology may be used for diagnosis of oral cancer, but some cancers may be missed or may be confused with abnormal non-cancerous cells.[5][6]
Barium swallow
- A barium swallow test may show any irregularities in the larynx, pharynx, mouth and surrounding areas and can detect small, early oral tumors.[7]
HPV testing
- For cancers of the throat, biopsy samples are often tested to see if HPV infection is present.
- This information can help predict the probable course of the cancer; for people whose cancers are linked to HPV, they tend to do better than those whose cancers are not.
Bone scan
- Bone scans may be done to check if there are rapidly dividing cells, such as cancer cells, in the bone (especially mandibular invasion).[8]
Dental Exam
- If radiation is part of the treatment plan for oral cancer, a dental exam beforehand by a prosthodontist is usually recommended.[9]
