Healthcare providers use a number system to stage most cancers. The stages of cancer are: Stage 0 cancer: There are abnormal cells, but they haven’t spread beyond where they started. Stage 0 can also refer to pre-cancerous cells. Most stage 0 cancers are curable. Stage I (1) cancer: The tumor is smaller and

Staging is the process of determining how much cancer is within the body (tumor size) and if it has spread. Learn about the TNM Staging system and other ways that stage is described.

TNM is a notation system that describes the stage of a cancer, which originates from a solid tumor, using alphanumeric codes: M describes distant metastasis (spread of cancer from one part of the body to another).

Once the values for T, N, and M (and any other factors that affect stage) have been determined, they are combined to assign an overall stage. For most cancers, the stage is a Roman numeral from I (1) to IV (4).

The tumor stage (T stage) describes the size of the primary tumor and how far it has grown into nearby tissues. It is one part of a more extensive pathologic staging system that describes how far the cancer has spread in the body. The tumor stage focuses only on the tumor itself – it does not include cancer in lymph nodes or other parts of the body. ...

There are 4 main T stages of prostate cancer – T1 to T4. T1 means the cancer is too small to be seen on a scan, or felt during an examination of the prostate. It’s divided into T1a, T1b and T1c. T1a means that the cancer is in less than 5% of the removed tissue. T1b means that the cancer is in 5% or more of the removed tissue.

Squamous cell carcinoma uses a TNM system to determine the different stages of this skin cancer. This article breaks down the stages and what it means for you.

TNM system stands for Tumour, Node and Metastasis. It is the most common way to stage lung cancer. Doctors may also use the number system. A simpler and older staging system is sometimes used for staging small cell lung cancer. It describes the cancer as limited disease or extensive disease.

Thyroid cancer stages range from I (1) through IV (4), sometimes with a letter after the number. As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more. Within a stage (1-4), an earlier letter means a lower stage.
