Frequently lung cancers are picked up on a routine chest X-ray in anyone experiencing no symptoms. If cancer cells begin to grow up in one of the bronchioles near the aveoli, the tumor could turn into the size of a golf ball or even larger without causing symptoms. Even when the chest X-ray looks normal, cancer might be assumed if the one has taken up blood, develops unrelenting hoarseness, has had repeated episodes of pneumonia in the same place in the lung, or has chest pain or trouble in breathing.
Lung cancer is a most significant disease after the age of fifty. Much more widespread in men than in women, its incidence rate is growing faster than any other type of cancer. The cause remains unidentified but remarkable evidence points to tobacco's guiltiness, even if automobile exhaust fumes and other gases are strongly suspected as well. Cancer in the lung frequently starts with a blameless cough which may be dry or productive of blood streaked sputum. The likely, perceptible difficulties are wheezing, hoarseness, pain in the chest, and weight loss, all indicating the potential presence of a serious disease.
Sometimes the initial sign of lung cancer is pneumonia, with fever. There might also be a cough with yellow sputum when the tumor closes a bronchial tube and infection expands behind the blockage. If a tumor extends directly from the lung into the tissues of the chest wall, it might lead to pain.
In view of the fact that lung cancer can typically be seen on the X-ray film, a chest X-ray is one of the first tests you will have. As with most types of X-ray pictures, a chest X-ray brings about no discomfort. But even if a tumor is not seen, the chest X-ray may offer other clues to the diagnosis, such as pneumonia in the lung.
Your doctor might want you to have a chest X-ray even though the diagnosis is already obvious. The intention is to be able to evaluate it with previous and later X-rays, to follow your progress and observe for likely changes in the lung tissue. It is significant for your doctor to realize whether the cancer is developing, or whether it is responding to treatment and shrinking.
