Stage 3 Lung Cancer

Localized cancer in a particular part of the lung is termed as Stage 1 but when the cancer has spread to the lymph nodes at the top of the lungs it is termed as Stage 2. Stage 3 lung cancer is when the cancer spreads to the chest walls. Stages of lung cancer are indicative of the degree of the spread of the cancer from its original source. Lung cancer staging is an important factor that affects the prognosis and the potential treatment for the disease. Non-small cell lung carcinoma is staged from IA to IV. The 'A' denotes the best prognosis while IV denotes worst prognosis.

Small cell lung carcinoma is classed as either limited or extensive stage. Limited stage is when the cancer is confined to one half of the chest and within the scope of a single radiotherapy field. Extensive stage is when the cancer has spread beyond one half of the chest.

Cancer staging is crucial because treatment is directly related to the stage of the disease. Incorrect staging could therefore lead to improper treatment and hence reduce the chances of survival. Specific staging systems are used for specific types of cancer.

Normally surgery is recommended to remove a malignant tumor found in Stage 3 lung cancer. When this does not suffice, the doctors may remove the lung to halt the growth of cancer cells. A combination of treatments may be used when treating some patients. In some cases, chemotherapy is administered before surgery for effective treatment.
