Diagnosis of oral cancer
Tests to diagnose oral cavity cancer, such as endoscopy, are done when symptoms or a routine exam suggests a problem. Learn about diagnosing oral cancer.
Grading oral cancer
Grading is a way of classifying oral cavity cancer cells based on their appearance and behaviour when viewed under a microscope. To find out the grade of a tumour, the biopsy sample is examined under a microscope. A grade is given based on how the cancer cells look and behave compared with normal cells.
Stages of oral cancer
Staging is a way of describing or classifying a cancer based on the extent of cancer in the body. The most common staging system for oral cavity cancer is the TNM system. The International Union Against Cancer (UICC) uses the TNM system to describe the extent of many solid tumour cancers.
If oral cancer spreads
Cancer cells have the potential to spread from the oral cavity to other parts of the body where they can grow into new tumours. This process is called metastasis. The tumours are also called metastasis (singular) or metastases (plural). Metastases are also called secondary tumours.
Supportive care for oral cancer
Supportive care helps people meet the physical, practical, emotional and spiritual challenges of oral cavity cancer. It is an important part of cancer care. There are many programs and services available to help meet the needs and improve the quality of life of people living with cancer and their loved ones, especially after treatment has ended.
