Lung cancer can affect anyone but people who smoke are at greater risk. There are four stages in lung cancer and when a person first approaches a doctor to report symptoms of lung cancer, the first process in the diagnosis of the disease is called staging. Based on the staging, a treatment regimen is charted out for the patient. |
Stage I is the earliest stage of cancer which could be detected in people and for people who have been diagnosed at this stage are very lucky as the disease can be easily cured at this stage without any side effects. However, the numbers of people who are diagnosed so early are very rare especially in lung cancer.
Stage II of lung cancer can hope to live up to five years or later after surgical treatment and out of every hundred cases of cancer about 50 cases are diagnosed in the second stage of lung cancer. Also, the numbers of people who will live for at least five years after diagnosis are about thirty or forty of them.
Stage III of lung cancer is divided into stage A and stage B further. Stage A is non small cell lung cancer and Stage B is small cell lung cancer. About 10 or 20 cases out of every hundred cases are diagnosed at this stage and people will still live for five years or more after being diagnosed with this type of cancer.
Stage IV is the most lethal level of cancer which has spread in many parts of the body and can also spread more. It is an advanced stage of cancer about 5 out of every hundred people is diagnosed with lung cancer at this stage.
