NCCN Guidelines for Patients® | Lung Cancer - Non-Small Cell Lung Cancer

26 NCCN Guidelines for Patients ® : Lung Cancer – Non-Small Cell, 2018 The 5 stages Guide 4 shows the five cancer stages labeled by Roman numerals 0–IV. Occult carcinoma is also included. Occult carcinoma is the finding of cancer cells in the absence of a tumor. The five stages are defined by TNM scores. The stages group tumors together that have a similar prognosis. A prognosis is the outlook (prediction) of the pattern and outcome of a disease. In general, earlier cancer stages have better outcomes. However, doctors define cancer stages with information from thousands of patients, so a cancer stage gives an average outcome. It may not tell the outcome for one person. Some people will do better than expected. Others will do worse. Other factors not used for staging cancer are also very important. Such factors include your general health and the type of lung cancer.
