NSCLC is any type of epithelial lung cancer other than small cell lung cancer (SCLC). The most common types of NSCLC are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma, but there are several other types that occur less frequently, and all types can occur in unusual histologic variants. Although NSCLCs are associated with cigarette smoke, adenocarcinomas may be found in patients who have never smoked. As a class, NSCLCs are relatively insensitive to chemotherapy and radiation therapy...
A portion of a lobe, a full lobe, or an entire lung may be removed. The extent of removal depends on the size of the tumor, its location, and how far it has spread.
A technique called cryosurgery is sometimes used for NSCLC. In cryosurgery, the tumor is frozen, which destroys it. This treatment is mainly reserved for patients who can’t tolerate traditional surgery.
Despite complete surgical removal, a large proportion of patients with early stage cancer have recurrence of cancer.
Surgery is not widely used in SCLC. Because SCLC spreads widely and rapidly through the body, removing it all by surgery is usually impossible.
An operation for lung cancer is major surgery. Many people experience pain, weakness, fatigue, and shortness of breath after surgery. Most have problems moving around, coughing, and breathing deeply. The recovery period can be several weeks or even months.
Video-assisted thoracoscopic surgery (VATS) is a less invasive type of surgery that is used when possible for the treatment of early stage NSCLC. Recovery from this type of surgery is usually quicker than with traditional surgery.
