Unfortunately, many people suffering from lung cancer is often diagnosed when it is in its early stages and is usually only discovered by accident, when even routine chest X-ray or CT (computer tomography) examination the doctor ordered another health issue. About 25% of all lung cancer patients do not show a tendency that the lung cancer is present, which means that when the disease is finally diagnosed, it is usually in the late and final stages. Other organs in the body at this stage is usually caused by some degree of damage. This damage is generally constant.
As the disease develops in the lungs, the outer tissues of the lung cancer cells invaded than other surrounding tissues. This allows the development of lung cancer to be able to spread to other organs in the body with relative ease. The disease can infiltrate the liver and the adrenal glands, which commonly occurs over a period of time without any appreciable symptom of the disease. If symptoms of visual problems are beginning to occur, it is usually because the lung cancer has spread to the brain, which may result in impairment of the attack. A lack of energy can be spotted.
Bones can also affect lung cancer, usually noticeable discomfort or vertebral (spine) and the ribs and thighs. The nerves can be infected, causing many patients to experience continuous aching pain (deltoids), shoulder, and the pain that runs along the outer side of the arm. Vocal cord may be affected if the cancer has spread to the esophagus (the channel that connects the mouth and stomach) causing difficulty swallowing. This is usually caused when a portion of the collapsed lung, a severe lung infection is difficult to treat.
Other common symptoms of lung cancer is caused by a loss of appetite and noticeable weight loss (usually occurring rapidly), headaches, sluggishness, memory loss problems, bleeding and clotting. These symptoms often go untreated for a long time before the disease feel the need to deal with them, as they often get linked to other, less serious health problems. When the late-stage disease has been diagnosed with lung cancer, the most damage has been caused to the body, so that patients with a low projection (life expectancy), typically five years when the disease was first diagnosed.
