The Most Common Methods Used in Determining Cancer Stages
When a cancer diagnosis is made, a physician will typically make an assessment as to what "stage" the cancer is in based upon how far the cancer has progressed or spread anatomically.
There are a few different types of staging systems which are used depending upon the type of cancer.
These staging systems apply to the majority of cancers except in the case of leukemia which is a cancer that affects the entire blood system and is not anatomically localized, however, there are certain types of leukemia which a stage is determined based upon how far advanced the condition is.
Identifying what stage the cancer is in helps in determining the prognosis and best form of treatment method to be used.
The Roman Numeral Staging System of Cancer The Roman numeral staging system utilizes the Roman numerals of I through IV and occasionally 0 with zero being the most curable stage of cancer and IV being cancer that have metastasized or spread and are typically inoperable.
Stage 0 is used to describe cancer which is found in its earliest form and typically curable with treatment.
Stage I is when the cancer is "restricted" or "localized" to one specific place within the body which are also typically curable with treatment.
Stage II is when the localized cancer has begun to spread away from its habitat and affect other parts of the body.
The prognosis for stage II cancer depends greatly on what type of cancer it is.
Stage III is very similar to stage II as it describes a localized cancer which has spread; however, this is typically used to describe cancer which has progressed farther than stage II cancer.
Stage IV describes the condition where cancer has metastasized to multiple locations throughout the body and is typically incurable or inoperable.
Tumor, Nodes, and Metastases - The TNM Stages of cancer The "TNM" staging system is used to describe the cancer stage of solid tumors within the body.
The "T" in "TMN" is the abbreviation for tumor and this "T" will be followed by a number which correlates with the system used in Roman numeral staging and indicates the advancement of the tumor.
The stages include T0 through T4, with T0 indicating a tumor which is in the earliest stages and has not begun to affect any other tissue and T4 being in a highly advanced stage and typically inoperable or incurable.
The "N" stands for nodes and describes the extent of the involvement of the lymph nodes.
The "N" is also followed by a number of 0 through 4 which indicates the severity.
The "M" is the "Metastasis" which is followed by either a 0 or a 1 with zero meaning the tumor has not spread or affected the lymph nodes and one meaning that the tumor has metastasized.
These are the basic systems which are used in cancer staging; however, there are other variations of these systems as well as other staging systems specific to certain types of cancer.
These stages are important when it comes to determining prognosis and treatment options, however, other things will also be factored in such as overall health and other specific tests including biochemical testing done on the cancer cells.
