Chemotherapy Lung Cancer

Chemotherapy Lung Cancer

Chemotherapy Systemic chemotherapy uses drugs that are injected into a vein or given by mouth. These drugs enter the bloodstream and reach all areas of the body, making this treatment potentially useful for cancers that have metastasised (spread) beyond the organ they started in. Lung cancer is the uncontrolled growth of abnormal cells in the lung. Normal lung tissue is made up of cells that are programmed by nature to create lungs of a certain shape and function. Sometimes the instructions to a cell go haywire and that cell and its offspring reproduce wildly, without regard for the shape and function of a lung. That wild reproduction can form tumors that clog up the lung and make it stop functioning as it should. Because of the large size of the lungs, cancer may grow for many years, undetected, without causing suspicion.
