- Stage 0: This is also known as carcinoma in situ. Cancer is only in the place where it started and has not spread. It is highly curable, usually by surgical removal.
- Stage I: This stage is usually a small cancer or tumor that has not grown deeply into nearby tissues. It has not spread to the lymph nodes or other areas. It is often called early-stage cancer.
- Stage II and III: These stages indicate larger cancers or tumors that have grown more deeply into nearby tissue. They may have also spread to lymph nodes but not to other parts of the body.
- Stage IV: This stage means that cancer has spread to other organs or parts of the body. It is also known as metastatic cancer or advanced cancer.
