Stages of lung cancer are used as a means of showing if cancer has distributed (and if so, how far it has spread). It is important to make a decision which of the stages best explains a particular development to plan treatment and to notice enhancement. There are two types of lung cancer: Small Cell Lung Cancer and Non-Small Cell Lung Cancer, and each type have different staging criteria. There are three Small Cell Lung Cancer stages: limited-stage, extensive-stage, and recurring. The Non-Small Cell stages are occult, stage 0, stage I, stage II, stage III, stage IV, and recurring.
Stages Of Lung Cancer: An Overview
After a lung cancer analysis has been made, assessments are performed to determine if cancer tissues have distribute within the breathing or to other places of the system.
The process used to find out if cancer has distributed within the breathing or to other places of the human body is called lung cancer staging. The information gathered from the staging process chooses the stage of lung cancer. It is important know the stage in order to plan lung cancer treatment and to notice enhancement.
There are two types of Lung cancer: Small Cell Lung Cancer and Non-Small Cell Lung Cancer. Each type of lung cancer has different staging criteria.
Specific Stages Of Non-Small Cell Lung Cancer Stages
Stages for Non-Small Cell Lung Cancer are divided into the following stages:
Occult Stage: In the occult (hidden) stage, cancer tissues are found in sputum (mucus coughed up from the lungs), but no development can be found in the lung by CT scan or bronchoscopy, or the main development is too small to be analysed.
Stage 0: In stage 0 lung cancers (carcinoma in situ), cancer is limited to the lung and is found only in a few stages of tissues. It has not expanded through the top coating of the lung.
Stage I: In stage I lung cancer (or stage 1 lung cancer), cancer is in the lung only, with regular tissues around the staging. Stage I is divided into stages IA and IB, based on the sizing the development.
Stage II: In stage II lung cancer (or stage 2 lung cancer), cancer has distribute to shut by lymph nodes or to stomach position wall (the rib crate and muscle tissue that make up the position of the program between the neck and the abdomen), the diaphragm (the thin muscle below the breathing and centre that differentiates stomach position from the abdomen), the mediastinal pleura (the thin tissue layer that includes the outside of the breathing in the position near the heart), or the parietal pericardium (the surface of tissues that involves the heart). Stage II is divided into stage IIA and stage IIB, based on the sizing the development and whether it has distribute to the lymph nodes.
Stage III: In stage III lung cancer (or stage 3 lung cancer), cancer has either:
- Spread to the lymph nodes in the mediastinum (the centre position between the breathing that contains the centre, major blood vessels, and other structures); or
- Spread to the lymph nodes on the opposite side of the chest or in the lower neck.
Stage III is divided into stage IIIA (which is sometimes managed with surgery) and stage IIIB (which is hardly ever managed with surgery).
Stage IV: In stage IV lung cancer (or stage 4 lung cancer), cancer has distribute to other places of the body or to another lobe of the breathing.
Recurrent: Recurrent Non-Small Cell Lung Cancer is cancer that has recurred (come back) after it has already been treated. The cancer may re-occur in the brain, lung, or other parts of the system.
Specific Stages Of Small Cell Lung Cancer
Small Cell Lung Cancer is divided into the following stages:
Limited-Stage: In limited-stage, cancer is found in one lung, into the tissue between the lungs, and nearby lymph nodes only.
Extensive-Stage: In extensive-stage, cancer has distributed outside of the lung in which it started spreading to other part of the system.
Recurrent: Recurrent Small Cell Lung Cancer is cancer that has recurred (come back) after it has been treated. The cancer may re-occur in the stomach position, nerve program, or in other parts of the body.
