Lung cancer forms in the tissues of your lungs generally in the cells which line your air passages.lung cancer is a very aggressive type of cancer and if not caught early enough can have a very poor outcome.
Generally, lung cancers originate in the lining of the bronchi. Plus it can also form in the glands below the lining of the bronchi, usually in the periphery of the lungs.
There are four recognizable stages of lung cancer. Stage one is the mildest and stage four is the most severe form. Remember though, that all stages of lung cancer are very serious.
Let us now examine the four stages:
Stage One: In this stage, the cancer is confined to the lung tissue will only. Your chance of recovering from this type of cancer is the best.
Stage Two: Here the cancer is confined to the lung tissue and lymph nodes only.
Stage Three: At this stage, the cancer is in the lung tissue and lymph nodes inside and outside the lungs.
Stage Four: When you reach this stage, the cancer has spread to the liver, bone, adrenal glands, brain, and other areas.
The state of development and the type of the cancer are very important when trying to heal the patient. There are two types: Non-Small Cell Lung Cancer, and Small Cell Lung Cancer. What follows are the likely treatments and approximate cure rates for each stage of lung cancer:
Stage One: The main treatment here involves surgery.
Cure rate is around 67%.
Stage Two: The main treatment for this type of cancer also involves surgery.
The cure rate for this type of cancer is generally in the 40 to 50% range.
Stage Three: The main treatment here includes chemotherapy and radiation.
The cure rates is generally less than 60%.
Stage Four: The main treatment involved here also includes chemotherapy and radiation. The cure rate at this stage is less than 80%.
Research is continually ongoing to study the causes of lung and other cancers, and to find new ways to prevent or even cure them.Unfortunately however, if you are diagnosed with lung cancer there is not a very good outlook attached to the outcome.
