Lung Cancer Stages

organized cancer depending on how far they spread. Staging of cancer correctly is essential to select the most appropriate treatment opciju.Broj diagnostic tests such as CT, MRI, bronchoscopy, blood, bone scans, a biopsy is used to find out how far the cancer has spread.

non-small cell lung cancer, which account for about 80 percent of lung cancer, was organized by using Roman numerals from 0 to IV. If the cancer is too small to be detected, it is called occult or hidden cancer and not assigned any numeral. Stage 0 cancer, or carcinoma in situ, is limited to the lungs and involves only a few cell layers. Phase I cancer is still confined to the lung, with an area of ​​normal tissue surrounding it. Stage I cancers are further divided into Stage IA and Stage IB, depending on the size of the tumor. In stage II cancer, the cancer may have spread to nearby lymph nodes, chest wall, diaphragm, or the tissue lining the lung (pleura) and the heart (pericardium). In stage III cancer of lymph nodes in the central chest or on the other side of the body from the original tumor were included. Stage III cancer is further divided into stage IIIA and stage IIIB. In stage IV cancer, the cancer has spread to other parts of the body, such as the liver, bones or brain, or other lung lobes. Cancer by stage from 0 to IIIA may be treated surgically. Treatment of stage III and stage IV cancers requires chemotherapy and radiotherapy.
