The outlook varies widely. Most often, NSCLC grows slowly and at first causes few or no symptoms. The cancer may spread to other parts of the body, including the bone, liver, small intestine, and brain.
However, in some cases, it can be extremely aggressive and cause rapid death. Chemotherapy has been shown to prolong the life and improve the quality of life in some patients with stage IV NSCLC.
Cure rates are related to the stage of disease and whether you are able to have surgery.
Stage I and II cancer can be cured with surgery, sometimes in more than 50% of cases.
Stage III tumors can be cured in some cases.
Patients with stage IV disease or cancer that has returned are almost never cured, and the goals of therapy are to extend and improve the quality of their life.
Cancer Term:(malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth, invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis, or spreading to other locations in the body via lymph or blood. These three malignant properties of cancers differentiate them from benign tumors, which do not invade or metastasize. Cancer-ar-foundation
