What are the signs and symptoms of lung cancer?
Many people with early lung cancer do not have symptoms, so the disease is often not diagnosed until after it has spread. Patients do not manifest any signs in the very early stages. Cough, shortness of breath, chest pain or blood in the sputum are among the early warning signs. Other signs of this illness could be a change of voice, hoarseness, weakness, fatigue,
and weight loss. The signs and symptoms of lung cancer are related to the location of the disease and the occurrence of paraneoplastic syndromes. Many patients present asymptomatically with a coin lesion discovered on a routine chest roentgenogram. The symptoms of centrally located lesions include cough, hemoptysis, wheezing, stridor, dyspnea, and postobstructive pneumonia. Peripheral lesions may result in pain from pleural or chest wall invasion, cough, or restrictive dyspnea.
Lung cancer may cause a number of symptoms. A cough is one of the more common ones and is likely to happen when a tumor grows and blocks an air passage. Another symptom is chest, shoulder, or back pain, which feels like a constant ache that may or may not be related to coughing. Other symptoms may include shortness of breath, fatigue, repeated pneumonia or bronchitis, coughing up blood, hoarseness, or swelling of the neck and face. There may also be symptoms that do not seem to be at all related to the lungs. These may be caused by the spread of lung cancer to other parts of the body. Depending on which organs are affected, symptoms can include headaches, weakness, pain, bone fractures, bleeding, or blood clots.
If the lung cancer has spread to other organs, the patient may have other symptoms such as headaches, bone fractures, pain, bleeding, or blood clots. Lung cancer may grow into certain nerves in the neck, causing a droopy eyelid, small pupil, sunken eye, and reduced perspiration on one side of the face. These symptoms are called Horner's syndrome. Lung cancer may grow directly into the esophagus, or it may grow near it and put pressure on it, leading to difficulty in swallowing. A lung cancer may grow into the heart, causing abnormal heart rhythms, blockage of blood flow through the heart, or fluid in the pericardial sac surrounding the heart.
