Manifestation by Organ System

Lung Cancer mainly attacks the lungs. The tumor grows in the lung and puts pressure on the chest cavity, causing breathing troubles and chronic coughing. Lung Cancer can spread to the chest cavity causing even more pain and can fill the heart cavity with fluid. Lung Cancer can also affect the bones. If Lung Cancer spreads to the bones, it is extremely painful and makes the bone brittle and easily breakable. Lung Cancer metastasizes earlier than other cancers and usually affects bone, the brain, the liver, and glands.
