How Is Mouth Cancer Diagnosed?
If your dentist or doctor suspects cancer, they’ll likely:
Perform a visual and physical exam
Order a biopsy (removing a small tissue sample)
Use imaging tests (like CT, MRI, or PET scans) to see if it has spread
Staging determines how far the cancer has progressed — crucial for treatment planning.

✅
Stage I
Small tumor (≤2 cm), no spread to nodes or distant sites
✅
