Several factors affect lung cancer survival rates. The type of cancer plays the stage where they, in the diagnosis and general condition of the patients a role in determining survival Cancer survival is usually described as a survival rate of five years, so the percentage of cancer patients who survive at least five years and diagnosed after cancer is, is expressed.
Studies have shown that the five year survival rate for patients with NSCLC as a function of the scene. Level 0 patients have better chances of survival, nearly 50 percent five years. About a quarter of the stage II patients survive five years compared to eight percent of patients with stage III and only two percent of patients in stage IV. In general, tends NSCLC, lead rapidly to the deadly disease. Ten to fifteen percent of patients with limited stage small cell lung cancer and between one and two percent of those affected to survive from the big stage cancer five years.
The estimates of cancer survival do not reflect the current progress in the treatment, which can lead to a better chance of survival because they usually calculated for a period of five years, which does not include the previous year. In addition, each treatment of a patient reacts in a unique way; No aggregated estimates for each factor, improve or worsen the chances of survival can be dispensed with.
The total number of deaths in the United States of lung cancer was increased in the 1980s, and began to fall for men in the 1990s, however, a similar decrease was not observed in women. More than fifty thousand current and former smokers were enrolled in the National Lung Screening Trial, whether undertaken incidence of lung cancer chest X-rays before the symptoms and CT scans can an early diagnosis and therefore the chances of survival.
