Through this article, we will explain the stage of the cancer of the lung in more detail.

Stage lung cancer

System the most common classification used most of the doctors are calcified stage TNM. Cancer is classified based on three factors, namely :
  • T indicates the size of the tumor and how far the tumor spread.
  • N indicates the involvement of tumor to the lymph nodes.
  • M indicates metastasis, or the spread of tumor to other body organs.
As an example the case, if the tumor is not found, then status becomes T0. If the cancer has spread to the lymph nodes, then his status becomes N1. There is a difference between the calcification stage lung cancer with cells that are small and large.

In non-small cell lung cancer (NSCLC), a type of cancer that dominates as much as 88% of cancer in America, a cure can be obtained in 70-75% of patients in stage 1. 45-50% of patients in stage 2, 20% of patients in stage 3, and almost nothing to the patient's stage 4.

Lung cancer with large cells

Lung cancer is more complex than lung cancer with small cells. The classification used is based on the stage of TNM. Below are the details :

  • Stage 1A. Cancer is found in the deepest layers of the lung and also found in lung tissue. The Tumor is not more than 3 cm and not attack the bronchi or lymph nodes.

  • Stage 1B. Cancer has grown larger and deeper in the lung tissue. The Tumor has grown through the lung into the pleura, with a diameter of more than 3 cm, or has spread to the main bronchus but has not attacked the lymph nodes. The treatment of lung cancer stage 1A/1B can be done through surgery and chemotherapy.

  • Stage 2A. Tumors with a diameter less than 3 cm has spread to the lymph nodes that are located on the same side with the area of the tumor.

  • Stage 2B. The Tumor has not spread to the lymph nodes, but has invaded the chest wall, the main bronchi, pleura, diaphragm, or heart tissue. Stage 2B means that the cancer has spread to the lymph nodes and one of the following conditions actually occur; the diameter of tumor more than 3 cm, the tumor has grown in the bronchi, or the tumor has grown in the pleura.

  • Stage 3A. In this stage, the tumors found in the lung and in the lymph nodes in the chest area the middle. Tumors in stage 3A can be removed surgically.

  • Stage 3B. The size of the tumor can vary. Lung cancer has attacked the lymph nodes and spread to both lungs, neck, heart, great vessels, or esophagus, so it can't be removed through surgery. The Tumor is at stage 3B is generally treated through chemotherapy and sometimes radiation therapy.

  • Stage 4. Lung cancer has spread to other parts of the body. Stage 4 is the stage that most end from lung cancer. stage 4 lung cancer symptoms of dying, The patient may be a candidate for a clinical trial to evaluate the efficacy and safety of new drugs.

Lung cancer with small cells

Stage 4 small cell lung cancer ( The advanced stage ) usually do not follow the classification of the stage of formal. This cancer tends to spread (metastasize) early and classified into two stages, namely early stage and advanced stage.

  • Early stage shows that lung cancer limited to one side of the chest.
  • Advanced stage indicates that the lung cancer has spread in areas outside the chest, such as the liver, adrenal glands, bones and brain.

Stage lung cancer will help the doctor determine the best treatment for You. Keep in mind that the stadium does not always indicate the outcome (prognosis) of lung cancer. The Prognosis depends on the condition of your overall health, strength, other medical conditions, and response to treatment.
