Further The Tumour Can Extend In Three Directions-:

Further the tumour can extend in three directions-: 1) in a bronchial tube gleam, forming growths; 2) in-filters a bronchial tube wall, extending on it as in a direction - of larger, and smaller bronchial tubes; 3) - sprouting between rings, extends then peri-bronhialno and forms tumoral knot or branches on a course of bronchial branches and vessels. On localisation a lung divide on central (starting with the main, share and segmentary bronchial tubes) and peripheral (starting with smaller bronchial tubes). Approximately at 60 % of patients the cancer is localised in the top departments - of lungs. Mark the central cancer more often, however at - some patients this cancer to carry to peripheral, sprouted in a large bronchial tube (so-called centralisation - of a peripheral cancer) more correctly-. The central cancer subdivide on two basic forms: en-dobronhialnyj ( and ), (central, branched out). Peripheral cancer divide into four forms: to an intradale-voi knot, subpleural tumours (including a cancer of a top - of a lung, or "a tumour of Pankosta"), the form, mi-liarnuju and forms.
