Details Of Cancer Stages

When cancer is diagnosed the doctor will go through steps to figure out the stage of the cancer. Cancer stages are used to help doctors form a treatment plan and to help patients understand the extent of their cancer and the prognosis. Staging cancer may seem confusing, but it is actually not that difficult to understand.

Defining Staging

Cancer stages are found out by a procedure called staging. Staging decides the harshness of cancer. It is experimented by the size of cancer and how it has spread throughout the body. The doctors perform further tests to examine the body for cancer and to find of where the cancer is, where it started and whether it’s spreading.

Importance of Staging

Staging helps in many ways. It is an important part of the process in determining how to treat the cancer. It is also useful for future research and understanding how that particular cancer reacts in the body. Here are the main reasons why staging is important:

• Helps form a treatment plan
• Helps in finding out a lung cancer prognosis
• Helpful in research studies

The Factors of Staging

Staging is completed by examining various factors. To keep up a level of consistency for the staging, there are some factors that are included in determining the stages of cancer. These factors are:

•  Location of the beginning of the cancer
• Number and size of tumors
• Type of cell and grade of the tumor
• Metastasis extent

The Systems of Staging

Lung cancer stages are identified on the basis of a system of staging. The most frequently used system is the TNM system. TNM stands for:

T stands for Tumor
N - Lymph Nodes
M stands for Metastasis

Every letter receives a number added to it to signify the level of the cancer regarding the tumor, lymph nodes and metastasis. The range numbers is from 0 to 4, with 0 being representative of none and 4 being the highest stage of cancer.

Cancer stages are generally based on the five stages of a simple chart. Here's how it looks:

Stage 0: Only early or pre-cancerous cells are present

Stage 1, 2 and 3: Cancer is present and may have spread in the localized area

Stage 4: Cancer has spread elsewhere in the body

Knowing the cancer stage is sometimes difficult, however it’s essential. Someone who receives a cancer diagnosis in stage 1 can know that the cancer is easier to cure and as a result the prognosis is probably good.
